OpenSSL 0.9.8x 是否支持 TLS1.2？我查看了 OpenSSL 的变更日志，但没有找到任何相关信息:https://www.openssl.org/news/changelog.html
最佳答案
关于 official changelog page you provided , 下 1.0.0h 和 1.0.1 之间的变化 [2012 年 3 月 14 日] 您可以看到初始 TLS v1.2 支持。
*) Add TLS v1.2 server support for client authentication. [Steve Henson]
*) Add TLS v1.2 client side support for client authentication. Keep cache of handshake records longer as we don't know the hash algorithm to use until after the certificate request message is received. [Steve Henson]
*) Initial TLS v1.2 client support. 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]
*) Initial TLSv1.1 support. Since TLSv1.1 is very similar to TLS v1.0 only a few changes are required [...]
TLS 1.2 支持来自 OpenSSL 版本 1.0.1 .
OpenSSL 0.9.8x 低于 1.0.1，因此不支持 TLS 1.2
