e3197e5a 21### Major changes between OpenSSL 1.1.1 and OpenSSL 3.0 [under development]
4477beac 22
ea780814 23 * Deprecated the `DSA_` functions.
f5a46ed7 24 * Deprecated the `ERR_load_` functions.
7d615e21 25 * Remove the `RAND_DRBG` API.
8dab4de5 26 * Deprecated the `ENGINE` API.
b4250010 27 * Added `OSSL_LIB_CTX`, a libcrypto library context.
eca47139 28 * Interactive mode is removed from the 'openssl' program.
19985ac4
P
29 * The X25519, X448, Ed25519, Ed448 and SHAKE256 algorithms are included in
30 the FIPS provider. None have the "fips=yes" property set and, as such,
31 will not be accidentially used.
4477beac
DMSP
32 * The algorithm specific public key command line applications have
33 been deprecated. These include dhparam, gendsa and others. The pkey
8c1cbc72 34 alternatives should be used instead: pkey, pkeyparam and genpkey.
4477beac
DMSP
35 * X509 certificates signed using SHA1 are no longer allowed at security
36 level 1 or higher. The default security level for TLS is 1, so
37 certificates signed using SHA1 are by default no longer trusted to
38 authenticate servers or clients.
5f8e6c50
DMSP
39 * enable-crypto-mdebug and enable-crypto-mdebug-backtrace were mostly
40 disabled; the project uses address sanitize/leak-detect instead.
e7774c28
DDO
41 * Added a Certificate Management Protocol (CMP, RFC 4210) implementation
42 also covering CRMF (RFC 4211) and HTTP transfer (RFC 6712).
8d9a4d83 43 It is part of the crypto lib and adds a 'cmp' app with a demo configuration.
e7774c28
DDO
44 All widely used CMP features are supported for both clients and servers.
45 * Added a proper HTTP(S) client to libcrypto supporting GET and POST,
46 redirection, plain and ASN.1-encoded contents, proxies, and timeouts.
16c6534b 47 * Added util/check-format.pl for checking adherence to the coding guidelines.
ece9304c 48 * Added OSSL_ENCODER, a generic encoder API.
be19d3ca 49 * Added OSSL_PARAM_BLD, an easier to use API to OSSL_PARAM.
5f8e6c50 50 * Added error raising macros, ERR_raise() and ERR_raise_data().
af2f14ac
RL
51 * Deprecated ERR_put_error(), ERR_get_error_line(), ERR_get_error_line_data(),
52 ERR_peek_error_line_data(), ERR_peek_last_error_line_data() and
53 ERR_func_error_string().
5f8e6c50
DMSP
54 * Added OSSL_PROVIDER_available(), to check provider availibility.
55 * Added 'openssl mac' that uses the EVP_MAC API.
56 * Added 'openssl kdf' that uses the EVP_KDF API.
57 * Add OPENSSL_info() and 'openssl info' to get built-in data.
58 * Add support for enabling instrumentation through trace and debug
59 output.
60 * Changed our version number scheme and set the next major release to
61 3.0.0
62 * Added EVP_MAC, an EVP layer MAC API, and a generic EVP_PKEY to EVP_MAC
63 bridge.
64 * Removed the heartbeat message in DTLS feature.
65 * Added EVP_KDF, an EVP layer KDF API, and a generic EVP_PKEY to EVP_KDF
66 bridge.
8c1cbc72 67 * All of the low-level MD2, MD4, MD5, MDC2, RIPEMD160, SHA1, SHA224,
4477beac
DMSP
68 SHA256, SHA384, SHA512 and Whirlpool digest functions have been
69 deprecated.
8c1cbc72 70 * All of the low-level AES, Blowfish, Camellia, CAST, DES, IDEA, RC2,
4477beac 71 RC4, RC5 and SEED cipher functions have been deprecated.
8c1cbc72 72 * All of the low-level DH, DSA, ECDH, ECDSA and RSA public key functions
4477beac 73 have been deprecated.
aba03ae5 74 * SSL 3, TLS 1.0, TLS 1.1, and DTLS 1.0 only work at security level 0.
