[REBOL] Encryption
From: mattsmac:hotm:ail at: 8-Sep-2003 9:13
Hi all,
I'm trying to implement a secure message transferring system using
blowfish ecryption in rebol/command using view/pro. Non-encrypted messages
transfer perfectly, and very short (like < 10 character) messages that are
encrypted work as well. Anytime I use a slightly longer message, expecially
if it includes puctuation, the transfer gets all screwed up. I'm using a
standard tcp port with the direct, lines, and no-wait refinements. The
no-wait is for another portion of the program, not the encryption. Here is
my encryption/decryption algorithm.
encrypt: func [data]
[
crypt-key: #{5C2486ADFD7F36765A7A163E86C6FB9A}
crypt-port: make port! [
scheme: 'crypt
algorithm: 'blowfish
direction: 'encrypt
strength: 128
key: crypt-key
padding: true
]
open crypt-port
insert crypt-port data
update crypt-port
crypt-data: copy crypt-port
close crypt-port
return crypt-data
]
decrypt: func [data]
[
crypt-key: #{5C2486ADFD7F36765A7A163E86C6FB9A}
decrypt-port: make port! [
scheme: 'crypt
algorithm: 'blowfish
direction: 'decrypt
strength: 128
key: crypt-key
padding: true
]
open decrypt-port
insert decrypt-port data
update decrypt-port
result: copy decrypt-port
close decrypt-port
return to-string result
]
