4477beac 22
92bc61e4
RL
23 * Deprecated the `OCSP_REQ_CTX` type and functions.
24 * Deprecated the `EC_KEY` and `EC_KEY_METHOD` types and functions.
25 * Deprecated the `RSA` and `RSA_METHOD` types and functions.
26 * Deprecated the `DSA` and `DSA_METHOD` types and functions.
27 * Deprecated the `DH` and `DH_METHOD` types and functions.

eca47139 32 * Interactive mode is removed from the 'openssl' program.
19985ac4
P
33 * The X25519, X448, Ed25519, Ed448 and SHAKE256 algorithms are included in
34 the FIPS provider. None have the "fips=yes" property set and, as such,
35 will not be accidentially used.
4477beac
DMSP
36 * The algorithm specific public key command line applications have
37 been deprecated. These include dhparam, gendsa and others. The pkey
8c1cbc72 38 alternatives should be used instead: pkey, pkeyparam and genpkey.
4477beac
DMSP
39 * X509 certificates signed using SHA1 are no longer allowed at security
40 level 1 or higher. The default security level for TLS is 1, so
41 certificates signed using SHA1 are by default no longer trusted to
42 authenticate servers or clients.

43 * enable-crypto-mdebug and enable-crypto-mdebug-backtrace were mostly
44 disabled; the project uses address sanitize/leak-detect instead.
e7774c28
DDO

46 also covering CRMF (RFC 4211) and HTTP transfer (RFC 6712).
8d9a4d83 47 It is part of the crypto lib and adds a 'cmp' app with a demo configuration.
e7774c28
DDO
48 All widely used CMP features are supported for both clients and servers.
49 * Added a proper HTTP(S) client to libcrypto supporting GET and POST,
50 redirection, plain and ASN.1-encoded contents, proxies, and timeouts.
16c6534b 51 * Added util/check-format.pl for checking adherence to the coding guidelines.
ece9304c 52 * Added OSSL_ENCODER, a generic encoder API.
be19d3ca 53 * Added OSSL_PARAM_BLD, an easier to use API to OSSL_PARAM.

af2f14ac
RL
55 * Deprecated ERR_put_error(), ERR_get_error_line(), ERR_get_error_line_data(),
56 ERR_peek_error_line_data(), ERR_peek_last_error_line_data() and
57 ERR_func_error_string().
5f8e6c50
DMSP
58 * Added OSSL_PROVIDER_available(), to check provider availibility.
59 * Added 'openssl mac' that uses the EVP_MAC API.
60 * Added 'openssl kdf' that uses the EVP_KDF API.
61 * Add OPENSSL_info() and 'openssl info' to get built-in data.
62 * Add support for enabling instrumentation through trace and debug
63 output.
64 * Changed our version number scheme and set the next major release to
65 3.0.0
66 * Added EVP_MAC, an EVP layer MAC API, and a generic EVP_PKEY to EVP_MAC
67 bridge.
68 * Removed the heartbeat message in DTLS feature.
69 * Added EVP_KDF, an EVP layer KDF API, and a generic EVP_PKEY to EVP_KDF
70 bridge.
8c1cbc72 71 * All of the low-level MD2, MD4, MD5, MDC2, RIPEMD160, SHA1, SHA224,
4477beac
DMSP
72 SHA256, SHA384, SHA512 and Whirlpool digest functions have been
73 deprecated.

4477beac 75 RC4, RC5 and SEED cipher functions have been deprecated.
8c1cbc72 76 * All of the low-level DH, DSA, ECDH, ECDSA and RSA public key functions
4477beac 77 have been deprecated.
aba03ae5 78 * SSL 3, TLS 1.0, TLS 1.1, and DTLS 1.0 only work at security level 0.
