    Dynamically added cipher suites

    Cipher suites are added to emSSH dynamically, at runtime, totally eliminating the nightmare of "configuration spaghetti" preprocessor symbols. When the required cipher suites are known it is possible to create a minimal size configuration by not linking in unused algorithms.

    The following list shows the cipher suites which are available in emSSH:
