# cipherkeygen.pl

# generates a cipher key of the format \d{4}[a-zA-Z]{4}\d{4}[a-zA-Z]{4}.
# because I'm lazy and not random enough.
# and because the utilities/perl directory is kinda bare...


# let's get a base key of \d{4}[A-Z]{4}\d{4}[A-Z]{4}
$key = int(rand() * 10) . int(rand() * 10) . int(rand() * 10) . int(rand() * 10) . chr(int(rand() * 26) + 0x41) . chr(int(rand() * 26) + 0x41) . chr(int(rand() * 26) + 0x41) . chr(int(rand() * 26) + 0x41) . int(rand() * 10) . int(rand() * 10) . int(rand() * 10) . int(rand() * 10) . chr(int(rand() * 26) + 0x41) . chr(int(rand() * 26) + 0x41) . chr(int(rand() * 26) + 0x41) . chr(int(rand() * 26) + 0x41);
