I have, for example, OpenSSL version 1.0.0o
on my Linux system, and I want to know which SSL/TLS
versions are supported with this build.
Is there a shell command to accomplish this?
SSL/TLS versions currently supported by OpenSSL 1.0. 2 are SSLv2, SSLv3, TLS1. 0, TLS1. 1 and TLS1.
Click on: Start -> Control Panel -> Internet Options 2. Click on the Advanced tab 3. Scroll to the bottom and check the TLS version described in steps 3 and 4: 4. If Use SSL 2.0 is enabled, you must have TLS 1.2 enabled (checked) 5.
Browse to Tools → Internet options → Advanced. 2. Under Security section, you will see a list of SSL and TLS protocols supported. Enable Use TLS 1.2 if present.
Use this
openssl ciphers -v | awk '{print $2}' | sort | uniq
