Null encryption
From Wikipedia, the free encyclopedia
Template:Short description Script error: No such module "about". In modern cryptography, null encryption (or selecting null cipher or NONE cipher) is choosing not to use encryption in a system where various encryption options are offered. When this option is used, the text is the same before and after encryption, which can be practical for testing/debugging, or authentication-only communication. In mathematics such a function is known as the identity function.
Examples of this are the "eNULL" cipher suite in OpenSSL,[1] and the "NULL Encryption Algorithm" in IPSec.[2]
