car --decode [.carfile]


Creates and decodes portable cross-platform crytographic archives. An archive can be a collection of files, or an in-stream message that is piped. Output can be to a binary .car file, or ascified text. A symmetric cipher is used, and the passhrase is hashed to form a key.


Specify symmetric cipher. By default 256 bit aes is used.
Specify decryption operation on an existing car stream or file. If no file is specified, stdin is used.
Specify name of digest algorithm. By default sha will be used.
Dereference and follow symlinks. Otherwise they are ignored.
Specify output file for a new archive. By default stdout is used.
Always overwrite existing files without prompting.
Non-interactive and no status output.
If argument is a directory, recursively scan directory and any subdirectory contents as arguments.
Outputs help screen for the user.
