I used the gpg method you describe below. However, it occurred to me that there is nothing stopping someone from potentially cracking an ftp server, and changing the iso image, while leaving the asc file intact. So, doing gpg --verify <ascfilename> would still tell you the signature is correct, even though the iso(s) had been messed with. Am I missing something here, or is this train of thought actually correct. If this train of thought is correct, then what's the point of the .asc file, other then to give an unsuspecting user a false sense of security?
