An ASC file is an armored ASCII file used by Pretty Good Privacy (PGP), an encryption program used for secure communication. It contains a digitally signed message and may store plain-text written information, as well as binary information encoded as text. ASC files also include a key as clear-signed text, which can be verified using PGP authentication methods.
