What version of TLS does OpenSSL support?

SSL/TLS versions currently supported by OpenSSL 1.0. 2 are SSLv2, SSLv3, TLS1. 0, TLS1. 1 and TLS1.

How do I check OpenSSL TLS version?

You should use openssl s_client, and the option you are looking for is -tls1_2. If you get the certificate chain and the handshake you know the system in question supports TLS 1.2. If you see don't see the certificate chain, and something similar to "handshake error" you know it does not support TLS 1.2.

Is OpenSSL safe?

Any OpenSSL internal use of this cipher, including in SSL/TLS, is safe because no such use sets such a long nonce value. However user applications that use this cipher directly and set a non-default nonce length to be longer than 12 bytes may be vulnerable. OpenSSL versions 1.1. 1 and 1.1.

How do I know if OpenSSL is installed on Linux?

In my case this is how I got the information:

1. find where apache logs are located, and go there, in my case: cd /var/log/apache2.
2. find in which log openssl information can be found: grep -i apache.*openssl *_log. ...
3. to get fresh information, restart apache, e.g. ...
4. check for last entries in the log, e.g.
