Okay, I admit it I don't know everything. What does the perl script actually do.
It does RSA encrypt/decrypt, works with keys up to 1024 bits (and larger).
I saved to file, chmod 777 perly tried running the script and kept getting error line 3.
You need two utils installed on your machine: perl and dc. Not having dc would cause an error on line 3. Try getting gnu dc (bc-1.03.tar.gz from gnu sites, see: http://www.dcs.ex.ac.uk/~aba/rsa/dc.html )
What does it do, does it encrypt a file or what. What Have i done wrong?
To encrypt: rsa -k=11 -n=ca1 < plaintext > ciphertext to decrypt: rsa -d -k=ac1 -n=ca1 < ciphertext > out you can extract pgp keys to use with it, that was a 32 bit key for demonstrational purposes and offers no security. See: http://www.dcs.ex.ac.uk/~aba/rsa/pgpacket.html for extracting pgp keys in hex format. Adam
