match an algorithm name.
--follow

--decrypt
Specify decryption operation on an existing car stream or file. If no file is specified, stdin is used.
--digest=name
Specify name of digest algorithm. By default sha will be used.
--follow
Dereference and follow symlinks. Otherwise they are ignored.
--output=filename
Specify output file for a new archive. By default stdout is used.
--overwrite
Always overwrite existing files without prompting.
