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] + + *) 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 @@ -224,15 +405,6 @@ *) Change the license to the Apache License v2.0.
