* 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.

level 1 or higher. The default security level for TLS is 1, so
certificates signed using SHA1 are by default no longer trusted to

SHA256, SHA384, SHA512 and Whirlpool digest functions have been
deprecated.
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.
+ * SSL 3, TLS 1.0, TLS 1.1, and DTLS 1.0 only work at security level 0,
+ except when RSA key exchange without SHA1 is used.
+ * Added providers, a new pluggability concept that will replace the
+ ENGINE API and ENGINE implementations.
