Add a default signature algorithms + extension including all the algorithms we support. Parse new signature + format in client key exchange. Relax some ECC signing restrictions for + TLS v1.2 as indicated in RFC5246. + [Steve Henson] + + *) Add server support for TLS v1.2 signature algorithms extension. Switch + to new signature format when needed using client digest preference. + All server ciphersuites should now work correctly in TLS v1.2. No client + support yet and no support for client certificates. + [Steve Henson] + + *) Initial TLS v1.2 support. Add new SHA256 digest to ssl code, switch + to SHA256 for PRF when using TLS v1.2 and later. Add new SHA256 based + ciphersuites. At present only RSA key exchange ciphersuites work with + TLS v1.2. Add new option for TLS v1.2 replacing the old and obsolete + SSL_OP_PKCS1_CHECK flags with SSL_OP_NO_TLSv1_2. New TLSv1.2 methods + and version checking. + [Steve Henson] *) New option OPENSSL_NO_SSL_INTERN.
