Changes between 1.1.1 and 3.0.0 [xx XXX xxxx]
+ *) X509 certificates signed using SHA1 are no longer allowed at security
+ level 1 and above.
+ In TLS/SSL the default security level is 1. It can be set either
+ using the cipher string with @SECLEVEL, or calling
+ SSL_CTX_set_security_level(). If the leaf certificate is signed with SHA-1,
+ a call to SSL_CTX_use_certificate() will fail if the security level is not
+ lowered first.
+ Outside TLS/SSL, the default security level is -1 (effectively 0). It can
+ be set using X509_VERIFY_PARAM_set_auth_level() or using the -auth_level
+ options of the apps.
+ [Kurt Roeckx]
+
+ *) Reworked the treatment of EC EVP_PKEYs with the SM2 curve to
+ automatically become EVP_PKEY_SM2 rather than EVP_PKEY_EC.
+ This means that applications don't have to look at the curve NID and
+ 'EVP_PKEY_set_alias_type(pkey, EVP_PKEY_SM2)' to get SM2 computations.
+ However, they still can, that EVP_PKEY_set_alias_type() call acts as
+ a no-op when the EVP_PKEY is already of the given type.
+
+ Parameter and key generation is also reworked to make it possible
+ to generate EVP_PKEY_SM2 parameters and keys without having to go
+ through EVP_PKEY_EC generation and then change the EVP_PKEY type.
+ However, code that does the latter will still work as before.
+ [Richard Levitte]
+
+ *) Deprecated low level ECDH and ECDSA functions. These include:
+
+ ECDH_compute_key, ECDSA_do_sign, ECDSA_do_sign_ex, ECDSA_do_verify,
+ ECDSA_sign_setup, ECDSA_sign, ECDSA_sign_ex, ECDSA_verify and
+ ECDSA_size.
+
+ Use of these low level functions has been informally discouraged for a long
+ time. Instead applications should use the EVP_PKEY_derive(3),
+ EVP_DigestSign(3) and EVP_DigestVerify(3) functions.
+ [Paul Dale]
+
+ *) Deprecated the EC_KEY_METHOD functions. These include:
+
+ EC_KEY_METHOD_new, EC_KEY_METHOD_free, EC_KEY_METHOD_set_init,
+ EC_KEY_METHOD_set_keygen, EC_KEY_METHOD_set_compute_key,
+ EC_KEY_METHOD_set_sign, EC_KEY_METHOD_set_verify,
+ EC_KEY_METHOD_get_init, EC_KEY_METHOD_get_keygen,
+ EC_KEY_METHOD_get_compute_key, EC_KEY_METHOD_get_sign and
+ EC_KEY_METHOD_get_verify.
+
+ Instead applications and extension writers should use the OSSL_PROVIDER
+ APIs.
+ [Paul Dale]
+
+ *) Deprecated EVP_PKEY_decrypt_old(), please use EVP_PKEY_decrypt_init()
+ and EVP_PKEY_decrypt() instead.
+ Deprecated EVP_PKEY_encrypt_old(), please use EVP_PKEY_encrypt_init()
+ and EVP_PKEY_encrypt() instead.
+ [Richard Levitte]
+
+ *) Enhanced the documentation of EVP_PKEY_size(), EVP_PKEY_bits()
+ and EVP_PKEY_security_bits(). Especially EVP_PKEY_size() needed
+ a new formulation to include all the things it can be used for,
+ as well as words of caution.
+ [Richard Levitte]
+
+ *) The SSL_CTX_set_tlsext_ticket_key_cb(3) function has been deprecated.
+ Instead used the new SSL_CTX_set_tlsext_ticket_key_evp_cb(3) function.
+ [Paul Dale]
+
+ *) All of the low level HMAC functions have been deprecated including:
+ HMAC, HMAC_size, HMAC_CTX_new, HMAC_CTX_reset, HMAC_CTX_free,
+ HMAC_Init_ex, HMAC_Update, HMAC_Final, HMAC_CTX_copy, HMAC_CTX_set_flags
+ and HMAC_CTX_get_md.
+ Use of these low level functions has been informally discouraged for a long
+ time. Instead applications should use L<EVP_MAC_CTX_new(3)>,
+ L<EVP_MAC_CTX_free(3)>, L<EVP_MAC_init(3)>, L<EVP_MAC_update(3)>
+ and L<EVP_MAC_final(3)>.
+ [Paul Dale]
+
+ *) All of the low level CMAC functions have been deprecated including:
+ CMAC_CTX_new, CMAC_CTX_cleanup, CMAC_CTX_free, CMAC_CTX_get0_cipher_ctx,
+ CMAC_CTX_copy, CMAC_Init, CMAC_Update, CMAC_Final and CMAC_resume.
+ Use of these low level functions has been informally discouraged for a long
+ time. Instead applications should use L<EVP_MAC_CTX_new(3)>,
+ L<EVP_MAC_CTX_free(3)>, L<EVP_MAC_init(3)>, L<EVP_MAC_update(3)>
+ and L<EVP_MAC_final(3)>.
+ [Paul Dale]
+
+ *) All of the low level MD2, MD4, MD5, MDC2, RIPEMD160, SHA1, SHA224, SHA256,
+ SHA384, SHA512 and Whirlpool digest functions have been deprecated.
+ These include:
+
+ MD2, MD2_options, MD2_Init, MD2_Update, MD2_Final, MD4, MD4_Init,
+ MD4_Update, MD4_Final, MD4_Transform, MD5, MD5_Init, MD5_Update,
+ MD5_Final, MD5_Transform, MDC2, MDC2_Init, MDC2_Update, MDC2_Final,
+ RIPEMD160, RIPEMD160_Init, RIPEMD160_Update, RIPEMD160_Final,
+ RIPEMD160_Transform, SHA1_Init, SHA1_Update, SHA1_Final, SHA1_Transform,
+ SHA224_Init, SHA224_Update, SHA224_Final, SHA224_Transform, SHA256_Init,
+ SHA256_Update, SHA256_Final, SHA256_Transform, SHA384, SHA384_Init,
+ SHA384_Update, SHA384_Final, SHA512, SHA512_Init, SHA512_Update,
+ SHA512_Final, SHA512_Transform, WHIRLPOOL, WHIRLPOOL_Init,
+ WHIRLPOOL_Update, WHIRLPOOL_BitUpdate and WHIRLPOOL_Final.
+
+ Use of these low level functions has been informally discouraged
+ for a long time. Applications should use the EVP_DigestInit_ex(3),
+ EVP_DigestUpdate(3) and EVP_DigestFinal_ex(3) functions instead.
+ [Paul Dale]
+
+ *) Corrected the documentation of the return values from the EVP_DigestSign*
+ set of functions. The documentation mentioned negative values for some
+ errors, but this was never the case, so the mention of negative values
+ was removed.
+
+ Code that followed the documentation and thereby check with something
+ like 'EVP_DigestSignInit(...) <= 0' will continue to work undisturbed.
+ [Richard Levitte]
+
+ *) All of the low level cipher functions have been deprecated including:
+
+ AES_options, AES_set_encrypt_key, AES_set_decrypt_key, AES_encrypt,
+ AES_decrypt, AES_ecb_encrypt, AES_cbc_encrypt, AES_cfb128_encrypt,
+ AES_cfb1_encrypt, AES_cfb8_encrypt, AES_ofb128_encrypt,
+ AES_wrap_key, AES_unwrap_key, BF_set_key, BF_encrypt, BF_decrypt,
+ BF_ecb_encrypt, BF_cbc_encrypt, BF_cfb64_encrypt, BF_ofb64_encrypt,
+ BF_options, Camellia_set_key, Camellia_encrypt, Camellia_decrypt,
+ Camellia_ecb_encrypt, Camellia_cbc_encrypt, Camellia_cfb128_encrypt,
+ Camellia_cfb1_encrypt, Camellia_cfb8_encrypt, Camellia_ofb128_encrypt,
+ Camellia_ctr128_encrypt, CAST_set_key, CAST_encrypt, CAST_decrypt,

+ CAST_ofb64_encrypt, DES_options, DES_encrypt1, DES_encrypt2,
+ DES_encrypt3, DES_decrypt3, DES_cbc_encrypt, DES_ncbc_encrypt,
+ DES_pcbc_encrypt, DES_xcbc_encrypt, DES_cfb_encrypt, DES_cfb64_encrypt,
+ DES_ecb_encrypt, DES_ofb_encrypt, DES_ofb64_encrypt, DES_random_key,
+ DES_set_odd_parity, DES_check_key_parity, DES_is_weak_key, DES_set_key,
+ DES_key_sched, DES_set_key_checked, DES_set_key_unchecked,
+ DES_string_to_key, DES_string_to_2keys, DES_fixup_key_parity,
+ DES_ecb2_encrypt, DES_ede2_cbc_encrypt, DES_ede2_cfb64_encrypt,
+ DES_ede2_ofb64_encrypt, DES_ecb3_encrypt, DES_ede3_cbc_encrypt,
+ DES_ede3_cfb64_encrypt, DES_ede3_cfb_encrypt, DES_ede3_ofb64_encrypt,
+ DES_cbc_cksum, DES_quad_cksum, IDEA_encrypt, IDEA_options,
+ IDEA_ecb_encrypt, IDEA_set_encrypt_key, IDEA_set_decrypt_key,
+ IDEA_cbc_encrypt, IDEA_cfb64_encrypt, IDEA_ofb64_encrypt, RC2_set_key,
+ RC2_encrypt, RC2_decrypt, RC2_ecb_encrypt, RC2_cbc_encrypt,
+ RC2_cfb64_encrypt, RC2_ofb64_encrypt, RC4, RC4_options, RC4_set_key,
+ RC5_32_set_key, RC5_32_encrypt, RC5_32_decrypt, RC5_32_ecb_encrypt,
+ RC5_32_cbc_encrypt, RC5_32_cfb64_encrypt, RC5_32_ofb64_encrypt,
+ SEED_set_key, SEED_encrypt, SEED_decrypt, SEED_ecb_encrypt,
+ SEED_cbc_encrypt, SEED_cfb128_encrypt and SEED_ofb128_encrypt.
+
+ Use of these low level functions has been informally discouraged for
+ a long time. Applications should use the high level EVP APIs, e.g.
+ EVP_EncryptInit_ex, EVP_EncryptUpdate, EVP_EncryptFinal_ex, and the
+ equivalently named decrypt functions instead.
+ [Matt Caswell and Paul Dale]
+
+ *) Removed include/openssl/opensslconf.h.in and replaced it with
+ include/openssl/configuration.h.in, which differs in not including
+ <openssl/macros.h>. A short header include/openssl/opensslconf.h
+ was added to include both.
+
+ This allows internal hacks where one might need to modify the set
+ of configured macros, for example this if deprecated symbols are
+ still supposed to be available internally:
+
+ #include <openssl/configuration.h>
+
+ #undef OPENSSL_NO_DEPRECATED
+ #define OPENSSL_SUPPRESS_DEPRECATED
+
+ #include <openssl/macros.h>
+
+ This should not be used by applications that use the exported
+ symbols, as that will lead to linking errors.
+ [Richard Levitte]
+
+ *) Fixed an an overflow bug in the x64_64 Montgomery squaring procedure
+ used in exponentiation with 512-bit moduli. No EC algorithms are
+ affected. Analysis suggests that attacks against 2-prime RSA1024,
+ 3-prime RSA1536, and DSA1024 as a result of this defect would be very
+ difficult to perform and are not believed likely. Attacks against DH512
+ are considered just feasible. However, for an attack the target would
+ have to re-use the DH512 private key, which is not recommended anyway.
+ Also applications directly using the low level API BN_mod_exp may be
+ affected if they use BN_FLG_CONSTTIME.
+ (CVE-2019-1551)
+ [Andy Polyakov]
+
+ *) Most memory-debug features have been deprecated, and the functionality
+ replaced with no-ops.
+ [Rich Salz]
+
+ *) Introduced a new method type and API, OSSL_SERIALIZER, to
+ represent generic serializers. An implementation is expected to
+ be able to serialize an object associated with a given name (such
+ as an algorithm name for an asymmetric key) into forms given by
+ implementation properties.
+
+ Serializers are primarily used from inside libcrypto, through
+ calls to functions like EVP_PKEY_print_private(),
+ PEM_write_bio_PrivateKey() and similar.
+
+ Serializers are specified in such a way that they can be made to
+ directly handle the provider side portion of an object, if this
+ provider side part comes from the same provider as the serializer
+ itself, but can also be made to handle objects in parametrized
+ form (as an OSSL_PARAM array of data). This allows a provider to
+ offer generic serializers as a service for any other provider.
+ [Richard Levitte]
+
+ *) Added a .pragma directive to the syntax of configuration files, to
+ allow varying behavior in a supported and predictable manner.
+ Currently added pragma:
+
+ .pragma dollarid:on
+
+ This allows dollar signs to be a keyword character unless it's
+ followed by a opening brace or parenthesis. This is useful for
+ platforms where dollar signs are commonly used in names, such as
+ volume names and system directory names on VMS.
+ [Richard Levitte]
+
+ *) Added functionality to create an EVP_PKEY from user data. This
+ is effectively the same as creating a RSA, DH or DSA object and
+ then assigning them to an EVP_PKEY, but directly using algorithm
+ agnostic EVP functions. A benefit is that this should be future
+ proof for public key algorithms to come.
+ [Richard Levitte]
+
+ *) Change the interpretation of the '--api' configuration option to
+ mean that this is a desired API compatibility level with no
+ further meaning. The previous interpretation, that this would
+ also mean to remove all deprecated symbols up to and including
+ the given version, no requires that 'no-deprecated' is also used
+ in the configuration.
+
+ When building applications, the desired API compatibility level
+ can be set with the OPENSSL_API_COMPAT macro like before. For
+ API compatibility version below 3.0, the old style numerical
+ value is valid as before, such as -DOPENSSL_API_COMPAT=0x10100000L.
+ For version 3.0 and on, the value is expected to be the decimal
+ value calculated from the major and minor version like this:
+
+ MAJOR * 10000 + MINOR * 100
+
+ Examples:
+
+ -DOPENSSL_API_COMPAT=30000 For 3.0
+ -DOPENSSL_API_COMPAT=30200 For 3.2
+
+ To hide declarations that are deprecated up to and including the
+ given API compatibility level, -DOPENSSL_NO_DEPRECATED must be
+ given when building the application as well.
+ [Richard Levitte]
+
+ *) Added the X509_LOOKUP_METHOD called X509_LOOKUP_store, to allow
+ access to certificate and CRL stores via URIs and OSSL_STORE
+ loaders.
+
+ This adds the following functions:
+
+ X509_LOOKUP_store()
+ X509_STORE_load_file()
+ X509_STORE_load_path()
+ X509_STORE_load_store()
+ SSL_add_store_cert_subjects_to_stack()
+ SSL_CTX_set_default_verify_store()
+ SSL_CTX_load_verify_file()
+ SSL_CTX_load_verify_dir()
+ SSL_CTX_load_verify_store()
+
+ Also, the following functions are now deprecated:
+
+ - X509_STORE_load_locations() (use X509_STORE_load_file(),
+ X509_STORE_load_path() or X509_STORE_load_store() instead)
+ - SSL_CTX_load_verify_locations() (use SSL_CTX_load_verify_file(),
+ SSL_CTX_load_verify_dir() or SSL_CTX_load_verify_store() instead)
+ [Richard Levitte]
+
+ *) Added a new method to gather entropy on VMS, based on SYS$GET_ENTROPY.
+ The presence of this system service is determined at run-time.
+ [Richard Levitte]
+
+ *) Added functionality to create an EVP_PKEY context based on data
+ for methods from providers. This takes an algorithm name and a
+ property query string and simply stores them, with the intent
+ that any operation that uses this context will use those strings
+ to fetch the needed methods implicitly, thereby making the port
+ of application written for pre-3.0 OpenSSL easier.
+ [Richard Levitte]
+
+ *) The undocumented function NCONF_WIN32() has been deprecated; for
+ conversion details see the HISTORY section of doc/man5/config.pod
+ [Rich Salz]
+
+ *) Introduced the new functions EVP_DigestSignInit_ex() and
+ EVP_DigestVerifyInit_ex(). The macros EVP_DigestSignUpdate() and
+ EVP_DigestVerifyUpdate() have been converted to functions. See the man
+ pages for further details.
+ [Matt Caswell]
+
+ *) Most common options (such as -rand/-writerand, TLS version control, etc)
+ were refactored and point to newly-enhanced descriptions in openssl.pod
+ [Rich Salz]
+
+ *) Over two thousand fixes were made to the documentation, including:
+ adding missing command flags, better style conformance, documentation
+ of internals, etc.
+ [Rich Salz, Richard Levitte]
+
+ *) s390x assembly pack: add hardware-support for P-256, P-384, P-521,
+ X25519, X448, Ed25519 and Ed448.
+ [Patrick Steuer]
+
+ *) Print all values for a PKCS#12 attribute with 'openssl pkcs12', not just
+ the first value.
+ [Jon Spillett]
+
+ *) Deprecated the public definition of ERR_STATE as well as the function
+ ERR_get_state(). This is done in preparation of making ERR_STATE an
+ opaque type.
+ [Richard Levitte]
+
+ *) Added ERR functionality to give callers access to the stored function
+ names that have replaced the older function code based functions.
+
+ New functions are ERR_get_error_func(), ERR_peek_error_func(),
+ ERR_peek_last_error_func(), ERR_get_error_data(), ERR_peek_error_data(),
+ ERR_peek_last_error_data(), ERR_get_error_all(), ERR_peek_error_all()
+ and ERR_peek_last_error_all().
+
+ These functions have become deprecated: ERR_get_error_line_data(),
+ ERR_peek_error_line_data(), ERR_peek_last_error_line_data() and
+ ERR_func_error_string().
+ [Richard Levitte]
+
+ *) Extended testing to be verbose for failing tests only. The make variables
+ VERBOSE_FAILURE or VF can be used to enable this:
+
+ $ make VF=1 test # Unix
+ $ mms /macro=(VF=1) test ! OpenVMS
+ $ nmake VF=1 test # Windows
+
+ [Richard Levitte]
+
+ *) For built-in EC curves, ensure an EC_GROUP built from the curve name is
+ used even when parsing explicit parameters, when loading a serialized key
+ or calling `EC_GROUP_new_from_ecpkparameters()`/
+ `EC_GROUP_new_from_ecparameters()`.
+ This prevents bypass of security hardening and performance gains,
+ especially for curves with specialized EC_METHODs.
+ By default, if a key encoded with explicit parameters is loaded and later
+ serialized, the output is still encoded with explicit parameters, even if
+ internally a "named" EC_GROUP is used for computation.
+ [Nicola Tuveri]
+
+ *) Compute ECC cofactors if not provided during EC_GROUP construction. Before
+ this change, EC_GROUP_set_generator would accept order and/or cofactor as
+ NULL. After this change, only the cofactor parameter can be NULL. It also
+ does some minimal sanity checks on the passed order.
+ (CVE-2019-1547)
+ [Billy Bob Brumley]
+
+ *) Fixed a padding oracle in PKCS7_dataDecode and CMS_decrypt_set1_pkey.
+ An attack is simple, if the first CMS_recipientInfo is valid but the
+ second CMS_recipientInfo is chosen ciphertext. If the second
+ recipientInfo decodes to PKCS #1 v1.5 form plaintext, the correct
+ encryption key will be replaced by garbage, and the message cannot be
+ decoded, but if the RSA decryption fails, the correct encryption key is
+ used and the recipient will not notice the attack.
+ As a work around for this potential attack the length of the decrypted
+ key must be equal to the cipher default key length, in case the
+ certifiate is not given and all recipientInfo are tried out.
+ The old behaviour can be re-enabled in the CMS code by setting the
+ CMS_DEBUG_DECRYPT flag.
+ [Bernd Edlinger]
+
+ *) Early start up entropy quality from the DEVRANDOM seed source has been
+ improved for older Linux systems. The RAND subsystem will wait for
+ /dev/random to be producing output before seeding from /dev/urandom.
+ The seeded state is stored for future library initialisations using
+ a system global shared memory segment. The shared memory identifier
+ can be configured by defining OPENSSL_RAND_SEED_DEVRANDOM_SHM_ID to
+ the desired value. The default identifier is 114.
+ [Paul Dale]
+
+ *) Revised BN_generate_prime_ex to not avoid factors 2..17863 in p-1
+ when primes for RSA keys are computed.
+ Since we previously always generated primes == 2 (mod 3) for RSA keys,
+ the 2-prime and 3-prime RSA modules were easy to distinguish, since
+ N = p*q = 1 (mod 3), but N = p*q*r = 2 (mod 3). Therefore fingerprinting
+ 2-prime vs. 3-prime RSA keys was possible by computing N mod 3.
+ This avoids possible fingerprinting of newly generated RSA modules.
+ [Bernd Edlinger]
+
+ *) Correct the extended master secret constant on EBCDIC systems. Without this
+ fix TLS connections between an EBCDIC system and a non-EBCDIC system that
+ negotiate EMS will fail. Unfortunately this also means that TLS connections
+ between EBCDIC systems with this fix, and EBCDIC systems without this
+ fix will fail if they negotiate EMS.
+ [Matt Caswell]
+
+ *) Changed the library initialisation so that the config file is now loaded
+ by default. This was already the case for libssl. It now occurs for both
+ libcrypto and libssl. Use the OPENSSL_INIT_NO_LOAD_CONFIG option to
+ OPENSSL_init_crypto() to suppress automatic loading of a config file.
+ [Matt Caswell]
+
+ *) Introduced new error raising macros, ERR_raise() and ERR_raise_data(),
+ where the former acts as a replacement for ERR_put_error(), and the
+ latter replaces the combination ERR_put_error()+ERR_add_error_data().
+ ERR_raise_data() adds more flexibility by taking a format string and
+ an arbitrary number of arguments following it, to be processed with
+ BIO_snprintf().
+ [Richard Levitte]
+
+ *) Introduced a new function, OSSL_PROVIDER_available(), which can be used
+ to check if a named provider is loaded and available. When called, it
+ will also activate all fallback providers if such are still present.
+ [Richard Levitte]
+
+ *) Enforce a minimum DH modulus size of 512 bits.
+ [Bernd Edlinger]
+
+ *) Changed DH parameters to generate the order q subgroup instead of 2q.
+ Previously generated DH parameters are still accepted by DH_check
+ but DH_generate_key works around that by clearing bit 0 of the
+ private key for those. This avoids leaking bit 0 of the private key.
+ [Bernd Edlinger]
+
+ *) Significantly reduce secure memory usage by the randomness pools.
+ [Paul Dale]
+
+ *) {CRYPTO,OPENSSL}_mem_debug_{push,pop} are now no-ops and have been
+ deprecated.
+ [Rich Salz]
+
+ *) A new type, EVP_KEYEXCH, has been introduced to represent key exchange
+ algorithms. An implementation of a key exchange algorithm can be obtained
+ by using the function EVP_KEYEXCH_fetch(). An EVP_KEYEXCH algorithm can be
+ used in a call to EVP_PKEY_derive_init_ex() which works in a similar way to
+ the older EVP_PKEY_derive_init() function. See the man pages for the new
+ functions for further details.
+ [Matt Caswell]
+
+ *) The EVP_PKEY_CTX_set_dh_pad() macro has now been converted to a function.
+ [Matt Caswell]
+
+ *) Removed the function names from error messages and deprecated the
+ xxx_F_xxx define's.
+
+ *) Removed NextStep support and the macro OPENSSL_UNISTD
+ [Rich Salz]
+
+ *) Removed DES_check_key. Also removed OPENSSL_IMPLEMENT_GLOBAL,
+ OPENSSL_GLOBAL_REF, OPENSSL_DECLARE_GLOBAL.
+ Also removed "export var as function" capability; we do not export
+ variables, only functions.
+ [Rich Salz]
+
+ *) RC5_32_set_key has been changed to return an int type, with 0 indicating
+ an error and 1 indicating success. In previous versions of OpenSSL this
+ was a void type. If a key was set longer than the maximum possible this
+ would crash.
+ [Matt Caswell]
+
+ *) Support SM2 signing and verification schemes with X509 certificate.
+ [Paul Yang]
+
+ *) Use SHA256 as the default digest for TS query in the ts app.
+ [Tomas Mraz]
+
+ *) Change PBKDF2 to conform to SP800-132 instead of the older PKCS5 RFC2898.
+ This checks that the salt length is at least 128 bits, the derived key
+ length is at least 112 bits, and that the iteration count is at least 1000.
+ For backwards compatibility these checks are disabled by default in the
+ default provider, but are enabled by default in the fips provider.
+ To enable or disable these checks use the control
+ EVP_KDF_CTRL_SET_PBKDF2_PKCS5_MODE.
+ [Shane Lontis]
+
+ *) Default cipher lists/suites are now available via a function, the
+ #defines are deprecated.
+ [Todd Short]
+
+ *) Add target VC-WIN32-UWP, VC-WIN64A-UWP, VC-WIN32-ARM-UWP and
+ VC-WIN64-ARM-UWP in Windows OneCore target for making building libraries
+ for Windows Store apps easier. Also, the "no-uplink" option has been added.
+ [Kenji Mouri]
+
+ *) Join the directories crypto/x509 and crypto/x509v3
+ [Richard Levitte]
+
+ *) Change the default RSA, DSA and DH size to 2048 bit instead of 1024.
+ This changes the size when using the genpkey app when no size is given. It
+ fixes an omission in earlier changes that changed all RSA, DSA and DH
+ generation apps to use 2048 bits by default.
+ [Kurt Roeckx]
+
+ *) Added command 'openssl kdf' that uses the EVP_KDF API.
+ [Shane Lontis]
+
+ *) Added command 'openssl mac' that uses the EVP_MAC API.
+ [Shane Lontis]
+
+ *) Added OPENSSL_info() to get diverse built-in OpenSSL data, such
+ as default directories. Also added the command 'openssl info'
+ for scripting purposes.
+ [Richard Levitte]
+
+ *) The functions AES_ige_encrypt() and AES_bi_ige_encrypt() have been
+ deprecated. These undocumented functions were never integrated into the EVP
+ layer and implement the AES Infinite Garble Extension (IGE) mode and AES
+ Bi-directional IGE mode. These modes were never formally standardised and
+ usage of these functions is believed to be very small. In particular
+ AES_bi_ige_encrypt() has a known bug. It accepts 2 AES keys, but only one
+ is ever used. The security implications are believed to be minimal, but
+ this issue was never fixed for backwards compatibility reasons. New code
+ should not use these modes.
+ [Matt Caswell]
+
+ *) Add prediction resistance to the DRBG reseeding process.
+ [Paul Dale]
+
+ *) Limit the number of blocks in a data unit for AES-XTS to 2^20 as
+ mandated by IEEE Std 1619-2018.
+ [Paul Dale]
+
+ *) Added newline escaping functionality to a filename when using openssl dgst.
+ This output format is to replicate the output format found in the '*sum'
+ checksum programs. This aims to preserve backward compatibility.
+ [Matt Eaton, Richard Levitte, and Paul Dale]
+
+ *) Removed the heartbeat message in DTLS feature, as it has very
+ little usage and doesn't seem to fulfill a valuable purpose.
+ The configuration option is now deprecated.
+ [Richard Levitte]
+
+ *) Changed the output of 'openssl {digestname} < file' to display the
+ digest name in its output.
+ [Richard Levitte]
+
*) Added a new generic trace API which provides support for enabling
instrumentation through trace output. This feature is mainly intended
as an aid for developers and is disabled by default. To utilize it,
'enable-buildtest-c++'.
[Richard Levitte]
+ *) Add Single Step KDF (EVP_KDF_SS) to EVP_KDF.
+ [Shane Lontis]
+
+ *) Add KMAC to EVP_MAC.
+ [Shane Lontis]
+
*) Added property based algorithm implementation selection framework to
the core.
[Paul Dale]
*) Change the license to the Apache License v2.0.
[Richard Levitte]
- *) Change the possible version information given with OPENSSL_API_COMPAT.
- It may be a pre-3.0.0 style numerical version number as it was defined
- in 1.1.0, and it may also simply take the major version number.

- Because of the version numbering of pre-3.0.0 releases, the values 0,
- 1 and 2 are equivalent to 0x00908000L (0.9.8), 0x10000000L (1.0.0) and

- memory from it's contents. This is done with a counter that will
+ memory from its contents. This is done with a counter that will
place alternating values in each byte. This can be used to solve
two issues: 1) the removal of calls to memset() by highly optimizing
compilers, and 2) cleansing with other values than 0, since those can
