-----------
-### Major changes between OpenSSL 1.1.1 and OpenSSL 3.0 alpha 16 [in pre-release]
+### Major changes between OpenSSL 1.1.1 and OpenSSL 3.0 [under development]
+ * Added migration guide to man7
+ * Implemented support for fully "pluggable" TLSv1.3 groups
* Added suport for Kernel TLS (KTLS)
* Changed the license to the Apache License v2.0.
* Moved all variations of the EVP ciphers CAST5, BF, IDEA, SEED, RC2,
RC4, RC5, and DES to the legacy provider.
* Moved the EVP digests MD2, MD4, MDC2, WHIRLPOOL and RIPEMD-160 to the legacy
provider.
+ * Added convenience functions for generating asymmetric key pairs.
* Deprecated the `OCSP_REQ_CTX` type and functions.
* Deprecated the `EC_KEY` and `EC_KEY_METHOD` types and functions.
* Deprecated the `RSA` and `RSA_METHOD` types and functions.
* Deprecated the `ENGINE` API.
* Added `OSSL_LIB_CTX`, a libcrypto library context.
* Interactive mode is removed from the 'openssl' program.
- * The X25519, X448, Ed25519, Ed448 and SHAKE256 algorithms are included in
- the FIPS provider. None have the "fips=yes" property set and, as such,
- will not be accidentially used.
- * The algorithm specific public key command line applications have
- been deprecated. These include dhparam, gendsa and others. The pkey
- alternatives should be used instead: pkey, pkeyparam and genpkey.
+ * The X25519, X448, Ed25519, Ed448, SHAKE128 and SHAKE256 algorithms are
+ included in the FIPS provider.
* X509 certificates signed using SHA1 are no longer allowed at security
level 1 or higher. The default security level for TLS is 1, so
certificates signed using SHA1 are by default no longer trusted to
also covering CRMF (RFC 4211) and HTTP transfer (RFC 6712).
It is part of the crypto lib and adds a 'cmp' app with a demo configuration.
All widely used CMP features are supported for both clients and servers.
- * Added a proper HTTP(S) client to libcrypto supporting GET and POST,
- redirection, plain and ASN.1-encoded contents, proxies, and timeouts.
+ * Added a proper HTTP client supporting GET with optional redirection, POST,
+ arbitrary request and response content types, TLS, persistent connections,
+ connections via HTTP(s) proxies, connections and exchange via user-defined
+ BIOs (allowing implicit connections), and timeout checks.
* Added util/check-format.pl for checking adherence to the coding guidelines.
* Added OSSL_ENCODER, a generic encoder API.
* Added OSSL_PARAM_BLD, an easier to use API to OSSL_PARAM.
* Changed our version number scheme and set the next major release to
3.0.0
* Added EVP_MAC, an EVP layer MAC API, and a generic EVP_PKEY to EVP_MAC
- bridge.
+ bridge. Supported MACs are: BLAKE2, CMAC, GMAC, HMAC, KMAC, POLY1305
+ and SIPHASH.
* Removed the heartbeat message in DTLS feature.
- * Added EVP_KDF, an EVP layer KDF API, and a generic EVP_PKEY to EVP_KDF
- bridge.
+ * Added EVP_KDF, an EVP layer KDF and PRF API, and a generic EVP_PKEY to
+ EVP_KDF bridge. Supported KDFs are: HKDF, KBKDF, KRB5 KDF, PBKDF2,
+ PKCS12 KDF, SCRYPT, SSH KDF, SSKDF, TLS1 PRF, X9.42 KDF and X9.63 KDF.
* All of the low-level MD2, MD4, MD5, MDC2, RIPEMD160, SHA1, SHA224,
SHA256, SHA384, SHA512 and Whirlpool digest functions have been
deprecated.
