Description:
Catenates files while decrypting PGP-encrypted sections
Guncat acts like unix's cat command, but handles (partially) encrypted sections of processed files. Sections of guncat's input files which are surrounded by -----BEGIN PGP MESSAGE----- and -----END PGP MESSAGE----- markers are decrypted before being concatenated to the standard output stream. . Guncat's output (i.e., the standard output stream) may subsequently be processed by other programs, like grep or less. Guncat supports reading a decryption passphrase either from stdin or from gpg-agent. . Guncat stands for (Gpg UNencrypting CAT) and was designed to facilitate searching through (partially) PGP encrypted files, as encountered in mailboxes, for example.
