 - [OpenSSL 1.1.0](#openssl-110)
 - [OpenSSL 1.0.2](#openssl-102)

OpenSSL 3.0
-----------

### Major changes between OpenSSL 1.1.1 and OpenSSL 3.0 [under development]

  * Remove the `RAND_DRBG` API.
  * Deprecated the `ENGINE` API.
  * Added `OPENSSL_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.
  * 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
    authenticate servers or clients.
  * enable-crypto-mdebug and enable-crypto-mdebug-backtrace were mostly
    disabled; the project uses address sanitize/leak-detect instead.
  * Added a Certificate Management Protocol (CMP, RFC 4210) implementation
    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 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.
  * Added error raising macros, ERR_raise() and ERR_raise_data().
  * Deprecated ERR_put_error().
  * Added OSSL_PROVIDER_available(), to check provider availibility.
  * Added 'openssl mac' that uses the EVP_MAC API.
  * Added 'openssl kdf' that uses the EVP_KDF API.
  * Add OPENSSL_info() and 'openssl info' to get built-in data.
  * Add support for enabling instrumentation through trace and debug
    output.
  * 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.
  * Removed the heartbeat message in DTLS feature.
  * Added EVP_KDF, an EVP layer KDF API, and a generic EVP_PKEY to EVP_KDF
    bridge.
  * All of the low-level MD2, MD4, MD5, MDC2, RIPEMD160, SHA1, SHA224,
    SHA256, SHA384, SHA512 and Whirlpool digest functions have been
    deprecated.
  * All of the low-level AES, Blowfish, Camellia, CAST, DES, IDEA, RC2,
    RC4, RC5 and SEED cipher functions have been deprecated.
  * All of the low-level DH, DSA, ECDH, ECDSA and RSA public key functions
    have been deprecated.
  * SSL 3, TLS 1.0, TLS 1.1, and DTLS 1.0 only work at security level 0.
