API and Documentation Enhancements
+
+
X509 verification is now more strict so
+ X509_VERIFY_PARAM
+ host, ip or email failure will cause future
+ X509_verify_cert
+ calls to fail.
+
Support for single DES cipher suites is removed.
+
Support for RSASSA-PKCS1-v1_5 (RFC 8017) is added to
+ RSA_sign(3)
+
Modified signature of CRYPTO_mem_leaks_* to return -1. This function
+ is a no-op in LibreSSL, so this function returns an error to not
+ indicate the (non-)existence of memory leaks.
+
SSL_copy_session_id, PEM_Sign, EVP_EncodeUpdate, BIO_set_cipher,
+ X509_OBJECT_up_ref_count now return an int for error handling,
+ matching OpenSSL.
+
Converted a number of #defines into proper functions, matching
+ OpenSSL's ABI.
+
Added X509_get0_serialNumber from OpenSSL.
+
Removed EVP_PKEY2PKCS8_broken and PKCS8_set_broken, while adding
+ PKCS8_pkey_add1_attr_by_NID and PKCS8_pkey_get0_attrs, matching
+ OpenSSL.
+
Removed broken pkcs8 formats from openssl(1).
+
Added RSA_meth_get_finish() RSA_meth_set1_name() from OpenSSL.
+
Added new EVP_CIPHER_CTX_(get|set)_iv() API that allows the IV to be
+ retrieved and set with appropriate validation.
+
Extensive documentation updates and additional API history.
+
Made ENGINE_finish and ENGINE_free succeed on NULL and simplify callers
+ and matching OpenSSL behavior, rewrote ENGINE_* documentation.
+
Added const annotations to many existing APIs from OpenSSL, making
+ interoperability easier for downstream applications.
+
Documented security pitfalls with BN_FLG_CONSTTIME and constant-time
+ operation of BN_* functions.
+
+
Testing and Proactive Security
+
+
Added Wycheproof test support for ECDH, RSASSA-PSS, AES-GCM,
+ AES-CMAC, AES-CCM, AES-CBC-PKCS5, DSA, ChaCha20-Poly1305, ECDSA, and
+ X25519 test vectors. Applied appropriate fixes for errors uncovered by
+ tests.
+
Added more cipher tests, including all TLSv1.2 ciphers.
+
Added a blinding value when generating DSA and ECDSA signatures, in
+ order to reduce the possibility of a side-channel attack leaking the
+ private key.
+
Added timing-safe compares for checking results of signature
+ verification.
+
Added ECC constant time scalar multiplication support.
+ From Billy Brumley and his team at Tampere University of Technology.
+
+
+
Internal Improvements
+
+
Simplified key exchange signature generation and verification.
+
Converted more code paths to use CBB/CBS. All handshake messages are
+ now created by CBB. RSA key exchange is simplified and uses dedicated
+ buffers for secrets.
+
Simplified session ticket parsing and handling, inspired by
+ BoringSSL.
+
Stopped handing AES-GCM in ssl_cipher_get_evp, since they use the
+ EVP_AEAD interface.
+
Stopped using composite EVP_CIPHER AEADs.
+
Removed unused SSL3_FLAGS_DELAY_CLIENT_FINISHED and
+ SSL3_FLAGS_POP_BUFFER flags in write path, simplifying IO paths.
+
Updated BN_clear to use explicit_bzero.
+
Cleaned up BN_* implementations following changes made in OpenSSL by
+ Davide Galassi and others.
+
Revised the implementation of RSASSA-PKCS1-v1_5 to match the
+ specification in RFC 8017. Based on an OpenSSL commit by David
+ Benjamin.
+
+
+
Bug Fixes
+
+
Fixed a one-byte buffer overrun in callers of EVP_read_pw_string
+
Fixed various memory leaks found by Coverity.
+
Converted more functions in public API to use const arguments.
+
Correctly clear the current cipher state, when changing cipher state.
+ This fixed an issue where renegotion of cipher suites would fail
+ when switched from AEAD to non-AEAD or vice-versa.
+ Issue reported by Bernard Spil.
+
Fixed a pair of 20+ year-old bugs in X509_NAME_add_entry
+
Fixed a potential memory leak on failure in ASN1_item_digest
+
Fixed a potential memory alignment crash in asn1_item_combine_free
+
Fixed small timing side-channels in ecdsa_sign_setup and
+ dsa_sign_setup.
+
Added a missing bounds check in c2i_ASN1_BIT_STRING.
+
Fixed a potential leak/incorrect return value in DSA signature
+ generation.
