Note: This example requires Chilkat v9.5.0.96 or later.

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

# Symmetric keys, such as AES keys, are typically created (or imported) and used during a single session.
