Using CF's Decrypt(encrypted_string, key[, algorithm, encoding, IVorSalt,
iterations])
You should be able to do something like this...
Note, this is off the top of my head for TripleDES and I've not tested it in
the slightest. The only thing that really concerns me though is the chr(0)
in the middle of the StringBuffer append sequence. You may have to
experiment with how you build that ByteArray.
sb = createObject("java", "java.lang.StringBuffer");
sb.append(chr(27));
sb.append(chr(9));
sb.append(chr(45));
sb.append(chr(27));
sb.append(chr(0));
sb.append(chr(72));
sb.append(chr(171));
sb.append(chr(54));
IVector = sb.toString().getBytes(); // convert the StringBuffer to a
ByteArray
outputString = Decrypt(inputString, Hash(Key, "MD5"), "DESEDE", "Base64",
IVector);
