What is guncat
guncat is:
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.
