### Changes between 1.1.1 and 3.0 [xx XXX xxxx]
+ * Add a compile time option to prevent the caching of provider fetched
+ algorithms. This is enabled by including the no-cached-fetch option
+ at configuration time.
+
+ *Paul Dale*
+
+ * Combining the Configure options no-ec and no-dh no longer disables TLSv1.3.
+ Typically if OpenSSL has no EC or DH algorithms then it cannot support
+ connections with TLSv1.3. However OpenSSL now supports "pluggable" groups
+ through providers. Therefore third party providers may supply group
+ implementations even where there are no built-in ones. Attempting to create
+ TLS connections in such a build without also disabling TLSv1.3 at run time or
+ using third party provider groups may result in handshake failures. TLSv1.3
+ can be disabled at compile time using the "no-tls1_3" Configure option.
+
+ *Matt Caswell*
+
+ * The undocumented function X509_certificate_type() has been deprecated;
+ applications can use X509_get0_pubkey() and X509_get0_signature() to
+ get the same information.
+
+ *Rich Salz*
+
+ * Deprecated the obsolete BN_pseudo_rand() and BN_pseudo_rand_range()
+ functions. They are identical to BN_rand() and BN_rand_range()
+ respectively.
+
+ *Tomáš Mráz*
+
+ * Deprecated the obsolete X9.31 RSA key generation related functions
+ BN_X931_generate_Xpq(), BN_X931_derive_prime_ex(), and
+ BN_X931_generate_prime_ex().
+
+ *Tomáš Mráz*
+
+ * The default key generation method for the regular 2-prime RSA keys was
+ changed to the FIPS 186-4 B.3.6 method (Generation of Probable Primes with
+ Conditions Based on Auxiliary Probable Primes). This method is slower
+ than the original method.
+
+ *Shane Lontis*
+
+ * Deprecated the BN_is_prime_ex() and BN_is_prime_fasttest_ex() functions.
+ They are replaced with the BN_check_prime() function that avoids possible
+ misuse and always uses at least 64 rounds of the Miller-Rabin
+ primality test. At least 64 rounds of the Miller-Rabin test are now also
+ used for all prime generation, including RSA key generation.
+ This increases key generation time, especially for larger keys.
+
+ *Kurt Roeckx*
+
+ * Deprecated EVP_MD_CTX_set_update_fn() and EVP_MD_CTX_update_fn()
+ as they are not useful with non-deprecated functions.
+
+ *Rich Salz*
+
+ * Deprecated the type OCSP_REQ_CTX and the functions OCSP_REQ_CTX_new(),
+ OCSP_REQ_CTX_free(), OCSP_REQ_CTX_http(), OCSP_REQ_CTX_add1_header(),
+ OCSP_REQ_CTX_i2d(), OCSP_REQ_CTX_nbio(), OCSP_REQ_CTX_nbio_d2i(),
+ OCSP_REQ_CTX_get0_mem_bio() and OCSP_set_max_response_length(). These
+ were used to collect all necessary data to form a HTTP request, and to
+ perform the HTTP transfer with that request. With OpenSSL 3.0, the
+ type is OSSL_HTTP_REQ_CTX, and the deprecated functions are replaced
+ with OSSL_HTTP_REQ_CTX_new(), OSSL_HTTP_REQ_CTX_free(),
+ OSSL_HTTP_REQ_CTX_set_request_line(), OSSL_HTTP_REQ_CTX_add1_header(),
+ OSSL_HTTP_REQ_CTX_i2d(), OSSL_HTTP_REQ_CTX_nbio(),
+ OSSL_HTTP_REQ_CTX_sendreq_d2i(), OSSL_HTTP_REQ_CTX_get0_mem_bio() and
+ OSSL_HTTP_REQ_CTX_set_max_response_length().
+
+ *Rich Salz and Richard Levitte*
+
+ * Validation of SM2 keys has been separated from the validation of regular EC
+ keys, allowing to improve the SM2 validation process to reject loaded private
+ keys that are not conforming to the SM2 ISO standard.
+ In particular, a private scalar `k` outside the range `1 <= k < n-1` is now
+ correctly rejected.
+
+ *Nicola Tuveri*
+
+ * Behavior of the `pkey` app is changed, when using the `-check` or `-pubcheck`
+ switches: a validation failure triggers an early exit, returning a failure
+ exit status to the parent process.
+
+ *Nicola Tuveri*
+
+ * Changed behavior of SSL_CTX_set_ciphersuites() and SSL_set_ciphersuites()
+ to ignore unknown ciphers.
+
+ *Otto Hollmann*
+
+ * The `-cipher-commands` and `-digest-commands` options
+ of the command line utility `list` have been deprecated.
+ Instead use the `-cipher-algorithms` and `-digest-algorithms` options.
+
+ *Dmitry Belyavskiy*
+
+ * All of the low level EC_KEY functions have been deprecated including:
+
+ EC_KEY_OpenSSL, EC_KEY_get_default_method, EC_KEY_set_default_method,
+ EC_KEY_get_method, EC_KEY_set_method, EC_KEY_new_method
+ EC_KEY_METHOD_new, EC_KEY_METHOD_free, EC_KEY_METHOD_set_init,

+ EC_KEY_METHOD_get_verify,
+ EC_KEY_new_ex, EC_KEY_new, EC_KEY_get_flags, EC_KEY_set_flags,
+ EC_KEY_clear_flags, EC_KEY_decoded_from_explicit_params,
+ EC_KEY_new_by_curve_name_ex, EC_KEY_new_by_curve_name, EC_KEY_free,
+ EC_KEY_copy, EC_KEY_dup, EC_KEY_up_ref, EC_KEY_get0_engine,
+ EC_KEY_get0_group, EC_KEY_set_group, EC_KEY_get0_private_key,
+ EC_KEY_set_private_key, EC_KEY_get0_public_key, EC_KEY_set_public_key,
+ EC_KEY_get_enc_flags, EC_KEY_set_enc_flags, EC_KEY_get_conv_form,
+ EC_KEY_set_conv_form, EC_KEY_set_ex_data, EC_KEY_get_ex_data,
+ EC_KEY_set_asn1_flag, EC_KEY_generate_key, EC_KEY_check_key, EC_KEY_can_sign,
+ EC_KEY_set_public_key_affine_coordinates, EC_KEY_key2buf, EC_KEY_oct2key,
+ EC_KEY_oct2priv, EC_KEY_priv2oct and EC_KEY_priv2buf.
+ Applications that need to implement an EC_KEY_METHOD need to consider
+ implementation of the functionality in a special provider.
+ For replacement of the functions manipulating the EC_KEY objects
+ see the EVP_PKEY-EC(7) manual page.
+
+ Additionally functions that read and write EC_KEY objects such as
+ o2i_ECPublicKey, i2o_ECPublicKey, ECParameters_print_fp, EC_KEY_print_fp,
+ d2i_ECPKParameters, d2i_ECParameters, d2i_ECPrivateKey, d2i_ECPrivateKey_bio,
+ d2i_ECPrivateKey_fp, d2i_EC_PUBKEY, d2i_EC_PUBKEY_bio, d2i_EC_PUBKEY_fp,
+ i2d_ECPKParameters, i2d_ECParameters, i2d_ECPrivateKey, i2d_ECPrivateKey_bio,
+ i2d_ECPrivateKey_fp, i2d_EC_PUBKEY, i2d_EC_PUBKEY_bio and i2d_EC_PUBKEY_fp
+ have also been deprecated. Applications should instead use the
+ OSSL_DECODER and OSSL_ENCODER APIs to read and write EC files.
+
+ Finally functions that assign or obtain EC_KEY objects from an EVP_PKEY such as
+ EVP_PKEY_assign_EC_KEY, EVP_PKEY_get0_EC_KEY, EVP_PKEY_get1_EC_KEY and
+ EVP_PKEY_set1_EC_KEY are also deprecated. Applications should instead either
+ read or write an EVP_PKEY directly using the OSSL_DECODER and OSSL_ENCODER
+ APIs. Or load an EVP_PKEY directly from EC data using EVP_PKEY_fromdata().
+
+ *Shane Lontis, Paul Dale, Richard Levitte, and Tomáš Mráz*
+
+ * Deprecated all the libcrypto and libssl error string loading
+ functions: ERR_load_ASN1_strings(), ERR_load_ASYNC_strings(),
+ ERR_load_BIO_strings(), ERR_load_BN_strings(), ERR_load_BUF_strings(),
+ ERR_load_CMS_strings(), ERR_load_COMP_strings(), ERR_load_CONF_strings(),
+ ERR_load_CRYPTO_strings(), ERR_load_CT_strings(), ERR_load_DH_strings(),
+ ERR_load_DSA_strings(), ERR_load_EC_strings(), ERR_load_ENGINE_strings(),
+ ERR_load_ERR_strings(), ERR_load_EVP_strings(), ERR_load_KDF_strings(),
+ ERR_load_OBJ_strings(), ERR_load_OCSP_strings(), ERR_load_PEM_strings(),
+ ERR_load_PKCS12_strings(), ERR_load_PKCS7_strings(), ERR_load_RAND_strings(),
+ ERR_load_RSA_strings(), ERR_load_OSSL_STORE_strings(), ERR_load_TS_strings(),
+ ERR_load_UI_strings(), ERR_load_X509_strings(), ERR_load_X509V3_strings().
+
+ Calling these functions is not necessary since OpenSSL 1.1.0, as OpenSSL
+ now loads error strings automatically.
+
+ *Richard Levitte*
+
+ * The functions SSL_CTX_set_tmp_dh_callback and SSL_set_tmp_dh_callback, as
+ well as the macros SSL_CTX_set_tmp_dh() and SSL_set_tmp_dh() have been
+ deprecated. These are used to set the Diffie-Hellman (DH) parameters that
+ are to be used by servers requiring ephemeral DH keys. Instead applications
+ should consider using the built-in DH parameters that are available by
+ calling SSL_CTX_set_dh_auto() or SSL_set_dh_auto(). If custom parameters are
+ necessary then applications can use the alternative functions
+ SSL_CTX_set0_tmp_dh_pkey() and SSL_set0_tmp_dh_pkey(). There is no direct
+ replacement for the "callback" functions. The callback was originally useful
+ in order to have different parameters for export and non-export ciphersuites.
+ Export ciphersuites are no longer supported by OpenSSL. Use of the callback
+ functions should be replaced by one of the other methods described above.
+
+ *Matt Caswell*
+
+ * The `-crypt` option to the `passwd` command line tool has been removed.
+
+ *Paul Dale*
+
+ * The -C option to the `x509`, `dhparam`, `dsaparam`, and `ecparam` commands
+ were removed.
+
+ *Rich Salz*
+
+ * Add support for AES Key Wrap inverse ciphers to the EVP layer.
+ The algorithms are:
+ "AES-128-WRAP-INV", "AES-192-WRAP-INV", "AES-256-WRAP-INV",
+ "AES-128-WRAP-PAD-INV", "AES-192-WRAP-PAD-INV" and "AES-256-WRAP-PAD-INV".
+ The inverse ciphers use AES decryption for wrapping, and
+ AES encryption for unwrapping.
+
+ *Shane Lontis*
+
+ * Deprecated EVP_PKEY_set1_tls_encodedpoint() and
+ EVP_PKEY_get1_tls_encodedpoint(). These functions were previously used by
+ libssl to set or get an encoded public key in/from an EVP_PKEY object. With
+ OpenSSL 3.0 these are replaced by the more generic functions
+ EVP_PKEY_set1_encoded_public_key() and EVP_PKEY_get1_encoded_public_key().
+ The old versions have been converted to deprecated macros that just call the
+ new functions.
+
+ *Matt Caswell*
+
+ * The security callback, which can be customised by application code, supports
+ the security operation SSL_SECOP_TMP_DH. This is defined to take an EVP_PKEY
+ in the "other" parameter. In most places this is what is passed. All these
+ places occur server side. However there was one client side call of this
+ security operation and it passed a DH object instead. This is incorrect
+ according to the definition of SSL_SECOP_TMP_DH, and is inconsistent with all
+ of the other locations. Therefore this client side call has been changed to
+ pass an EVP_PKEY instead.
+
+ *Matt Caswell*
+
+ * Add PKCS7_get_octet_string() and PKCS7_type_is_other() to the public
+ interface. Their functionality remains unchanged.
+
+ *Jordan Montgomery*
+
+ * Added new option for 'openssl list', '-providers', which will display the
+ list of loaded providers, their names, version and status. It optionally
+ displays their gettable parameters.
+
+ *Paul Dale*
+
+ * Deprecated EVP_PKEY_set_alias_type(). This function was previously
+ needed as a workaround to recognise SM2 keys. With OpenSSL 3.0, this key
+ type is internally recognised so the workaround is no longer needed.
+
+ Functionality is still retained as it is, but will only work with
+ EVP_PKEYs with a legacy internal key.
+
+ *Richard Levitte*
+
+ * Deprecated `EVP_PKEY_CTX_set_rsa_keygen_pubexp()` and introduced
+ `EVP_PKEY_CTX_set1_rsa_keygen_pubexp()`, which is now preferred.
+
+ *Jeremy Walch*
+
+ * Changed all "STACK" functions to be macros instead of inline functions. Macro
+ parameters are still checked for type safety at compile time via helper
+ inline functions.
+
+ *Matt Caswell*
+
* Remove the RAND_DRBG API
The RAND_DRBG API did not fit well into the new provider concept as
implemented by EVP_RAND and EVP_RAND_CTX. The main reason is that the
RAND_DRBG API is a mixture of 'front end' and 'back end' API calls
and some of its API calls are rather low-level. This holds in particular
- for the callback mechanism (RAND_DRBG_set_callbacks()).
+ for the callback mechanism (`RAND_DRBG_set_callbacks()`).
Adding a compatibility layer to continue supporting the RAND_DRBG API as
a legacy API for a regular deprecation period turned out to come at the

and DTLS.
SSL_CTX instances that are created for a fixed protocol version (e.g.
- TLSv1_server_method()) also silently ignore version bounds. Previously
+ `TLSv1_server_method()`) also silently ignore version bounds. Previously
attempts to apply bounds to these protocol versions would result in an
error. Now only the "version-flexible" SSL_CTX instances are subject to
limits in configuration files in command-line options.
*Rich Salz and Richard Levitte*
- * Added a library context that applications as well as other
- libraries can use to form a separate context within which libcrypto
- operations are performed.
+ * Added a library context `OSSL_LIB_CTX` that applications as well as

There are two ways this can be used:

* 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

-------------
-### Changes between 1.1.1e and 1.1.1f [xx XXX xxxx]
+### Changes between 1.1.1i and 1.1.1j [xx XXX xxxx]
+
+ * Fixed SRP_Calc_client_key so that it uses constant time. The previous
+ implementation called BN_mod_exp without setting BN_FLG_CONSTTIME. This
+ could be exploited in a side channel attack to recover the password. Since
+ the attack is local host only this is outside of the current OpenSSL
+ threat model and therefore no CVE is assigned.
+
+ Thanks to Mohammed Sabt and Daniel De Almeida Braga for reporting this
+ issue.
+
+ *Matt Caswell*
+
+### Changes between 1.1.1h and 1.1.1i [8 Dec 2020]
+
+ * Fixed NULL pointer deref in the GENERAL_NAME_cmp function
+ This function could crash if both GENERAL_NAMEs contain an EDIPARTYNAME.
+ If an attacker can control both items being compared then this could lead
+ to a possible denial of service attack. OpenSSL itself uses the
+ GENERAL_NAME_cmp function for two purposes:
+ 1) Comparing CRL distribution point names between an available CRL and a
+ CRL distribution point embedded in an X509 certificate
+ 2) When verifying that a timestamp response token signer matches the
+ timestamp authority name (exposed via the API functions
+ TS_RESP_verify_response and TS_RESP_verify_token)
+ ([CVE-2020-1971])
+
+ *Matt Caswell*
+
+### Changes between 1.1.1g and 1.1.1h [22 Sep 2020]
+
+ * Certificates with explicit curve parameters are now disallowed in
+ verification chains if the X509_V_FLAG_X509_STRICT flag is used.
+
+ *Tomáš Mráz*
+
+ * The 'MinProtocol' and 'MaxProtocol' configuration commands now silently
+ ignore TLS protocol version bounds when configuring DTLS-based contexts, and
+ conversely, silently ignore DTLS protocol version bounds when configuring
+ TLS-based contexts. The commands can be repeated to set bounds of both
+ types. The same applies with the corresponding "min_protocol" and
+ "max_protocol" command-line switches, in case some application uses both TLS
+ and DTLS.
+
+ SSL_CTX instances that are created for a fixed protocol version (e.g.
+ TLSv1_server_method()) also silently ignore version bounds. Previously
+ attempts to apply bounds to these protocol versions would result in an
+ error. Now only the "version-flexible" SSL_CTX instances are subject to
+ limits in configuration files in command-line options.
+
+ *Viktor Dukhovni*
+
+ * Handshake now fails if Extended Master Secret extension is dropped
+ on renegotiation.
+
+ *Tomáš Mráz*
+
+ * The Oracle Developer Studio compiler will start reporting deprecated APIs
+
+### Changes between 1.1.1f and 1.1.1g [21 Apr 2020]
+
+ * Fixed segmentation fault in SSL_check_chain()
+ Server or client applications that call the SSL_check_chain() function
+ during or after a TLS 1.3 handshake may crash due to a NULL pointer
+ dereference as a result of incorrect handling of the
+ "signature_algorithms_cert" TLS extension. The crash occurs if an invalid
+ or unrecognised signature algorithm is received from the peer. This could
+ be exploited by a malicious peer in a Denial of Service attack.
+ ([CVE-2020-1967])
+
+ *Benjamin Kaduk*
+
+ * Added AES consttime code for no-asm configurations
+ an optional constant time support for AES was added
+ when building openssl for no-asm.
+ Enable with: ./config no-asm -DOPENSSL_AES_CONST_TIME
+ Disable with: ./config no-asm -DOPENSSL_NO_AES_CONST_TIME
+ At this time this feature is by default disabled.
+ It will be enabled by default in 3.0.
+
+ *Bernd Edlinger*
+
+### Changes between 1.1.1e and 1.1.1f [31 Mar 2020]
+
+ * Revert the change of EOF detection while reading in libssl to avoid
+ regressions in applications depending on the current way of reporting
+ the EOF. As the existing method is not fully accurate the change to
+ reporting the EOF via SSL_ERROR_SSL is kept on the current development
+ branch and will be present in the 3.0 release.
+
+ *Tomáš Mráz*
+
+ * Revised BN_generate_prime_ex to not avoid factors 3..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*

*Bodo Moeller; problem pointed out by Brice Canvel (EPFL),
Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and

perror when PEM_read_bio_X509_REQ fails, the error message must
be obtained from the error queue.
The syntax for the cipher sorting has been extended to support sorting by
cipher-strength (using the strength_bits hard coded in the tables).
- The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
+ The new command is `@STRENGTH` (see also `doc/apps/ciphers.pod`).
Fix a bug in the cipher-command parser: when supplying a cipher command
string with an "undefined" symbol (neither command nor alphanumeric
because it isn't possible to mix certificates and CRLs in DER format
without choking one or the other routine. Changed this to just read
a certificate: this is the best we can do. Also modified the code
- in apps/verify.c to take notice of return codes: it was previously
+ in `apps/verify.c` to take notice of return codes: it was previously
attempting to read in certificates from NULL pointers and ignoring
any errors: this is one reason why the cert and CRL reader seemed
to work. It doesn't check return codes from the default certificate
*Bodo Moeller*
- * New file apps/app_rand.c with commonly needed functionality
+ * New file `apps/app_rand.c` with commonly needed functionality
for handling the random seed file.
Use the random seed file in some applications that previously did not:

instead of using a fixed path.
*Bodo Moeller*
*Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)*
- * Run extensive memory leak checks on SSL apps. Fixed *lots* of memory

+ * First cut of a cleanup for `apps/`. First the `ssleay` program is now named
`openssl` and second, the shortcut symlinks for the `openssl <command>`
are no longer created. This way we have a single and consistent command
line interface `openssl <command>`, similar to `cvs <command>`.
*Ralf S. Engelschall*
* Removed dummy files from the 0.9.1b source tree:
