Hi there,
how can I verify the m0n0wall image using the public RSA signature?
thanks

The image files that can be downloaded have both an MD5 checksum and a SHA256 hash available to verify image integrity. You will need a program that verifies files against those types of checksums, or a program that generates those types of checksums from a file, and then you can manually compare them.
There are no detached RSA signatures available, AFAIK.

In addition to what Fred said - if you really want to check the embedded RSA signature instead of simply verifying the MD5/SHA256 hash: the source code of the signature verification utility is available here:
http://svn.m0n0.ch/wall/branches/freebsd6/build/tools/verifysig.c
And the public RSA key used to sign m0n0wall images is here:
