Supported cipher suites – emSSL

emSSL includes the most commonly used cipher suites, which allows connecting to nearly every TLS-supporting server.

Dynamically added cipher suites

Cipher suites are added to emSSL 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. This can be done by the compiler/linker automatically. With the included scan suites application, it is possible to determine which cipher suites are supposed by a particular server.

The following cipher suites are available in emSSL. The cipher suites are grouped by key exchange algorithm.
