symcryptrun is invoked this way:
symcryptrun --class CLASS --program PROGRAM --keyfile KEYFILE [--decrypt | --encrypt] [inputfile]
For encryption, the plain text must be provided on STDIN or as the argument inputfile, and the ciphertext will be output to STDOUT. For decryption vice versa.
CLASS describes the calling conventions of the external tool. Currently it must be given as ‘confucius’. PROGRAM is the full filename of that external tool.
For the class ‘confucius’ the option --keyfile is required; keyfile is the name of a file containing the secret key, which may be protected by a passphrase. For detailed calling conventions, see the source code.
Note, that gpg-agent must be running before starting symcryptrun.
The following additional options may be used:
