pembody
This is a utility for decoding PEM-encoded files and spewing their
contents to standard output. No trailing newline is appended. If
the filename is "-", pembody reads from standard input.
Example:
$ cat file.pem
-----BEGIN TEST DATA-----
c2FtcGxlIGJpbmFyeSBkYXRh
-----END TEST DATA-----
$ pembody file.pem
