Jun 13, 2004 · Starting with OpenSSL version 1.0.0, the openssl binary can generate prime numbers of a specified length: $ openssl prime -generate -bits 64 16148891040401035823 $ openssl prime -generate -bits 64 -hex E207F23B9AE52181 If you’re using a version of OpenSSL older than 1.0.0, you’ll have to pass a bunch of numbers to openssl and see what sticks.

In the next page see the Enabled SSL/TLS protocol versions section: Note: the more online services with SSL/TLS or vulnerability checkers can be found here . Manually from the side of Linux server To check which version of OpenSSL is running on NetScaler. Instructions. Create an SSH session to NetScaler, using your favourite SSH client. Run the command: There is no real way to check the SSL version on ESXi as the Posix environment in BusyBox does not have this capability. However, checking 'versions' is not the best way to see if OpenSSL has been patched. Many versions of OpenSSL actually have the 'patch' for this backported. RedHat is notorious for doing this. openssl-version, version - print OpenSSL version information SYNOPSIS openssl version [-help] [-a] [-v] [-b] [-o] [-f] [-p] [-d] [-e] DESCRIPTION This command is used to print out version information about OpenSSL. OPTIONS-help Print out a usage message. -a all information, this is the same as setting all the other flags. -v the current OpenSSL And keep in mind that you'll have to use a version of OpenSSL which does TLS 1.2, and that means CentOS 5 is right out. – Michael Hampton Oct 21 '14 at 20:49 14

openssl s_client. The simplest way to check support for a given version of SSL / TLS is via openssl s_client. openssl comes installed by default on most unix systems. Checking for TLS 1.0 support can be done with the following command…

In OpenSSL this master_secret is kept within the SSL Session SSL_SESSION. The initial handshake can provide server authentication, client authentication or no authentication at all. Default usage in HTTPS is to verify server authenticity with trusted Certificate Authorities known by the browser.
