SRTP uses Advanced Encryption Standard (AES) as the default cipher. This includes two cipher modes: Segmented Integer Counter Mode and f8-mode. The NULL cipher does not perform any encryption, and instead operates as an identity function. It copies the input stream directly to the output stream without any changes.
