SigChkTl-1.01.zip (58K) a zipped hfs disk image and checksum file. The disk image can be mounted with Mini vMac. Includes source code.
SigChkTl is a command line version of SigCheck. It can be used in Macintosh Programmer’s Workshop to automate checking digital signatures through out this website. It is written to be platform independent, using the C standard library, and would probably be easy to port to other platforms (but that is not supported).
It takes two arguments: First, a path to a file containing a signed message. And second, a path to a file containing a public key, in ascii armored format.
If the signature is correctly signed, SigChkTl will return a zero result ("{status}" in MPW). Otherwise the result will be non-zero.
SigChkTl is in part descended from MacPGP source code, which, as far as I can tell, allows derived works for noncommercial use.
Here is the md5 checksum for the download, signed with Gryphel Key 5:
