PEM === Set of functions for encapsulating data according to the PEM format. PEM (Privacy Enhanced Mail) was an IETF standard for securing emails via a Public Key Infrastructure. It is specified in RFC 1421-1424. Even though it has been abandoned, the simple message encapsulation it defined is still widely used today for encoding *binary* cryptographic objects like keys and certificates into text. .. automodule:: Crypto.IO.PEM :members:
