Changes between 1.1.1 and 3.0.0 [xx XXX xxxx]
+ *) 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
+ 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
