Jeff, I downloaded an eval of DynCrypto and gave it a try.
Usually it is very hard to figure out how passwords are turned into 128-bit keys, but since DynCrypto only offers one hash function - SHA1 - a little experimenting showed that they use the first 128 bits (32 hex digits) of the SHA1 hash of the password as the key. ZeroBytePadding is a bit unusual, but fortunately it was one of the seven padding methods available in BouncyCastle. Try this, where myPassword is the password and myCipherText is the encrypted data: -------------------------------------------------- <cfset key = ToBase64(BinaryDecode(Left(Hash(myPassword,"SHA1"),32),"Hex")) > <cfset myClearText = Decrypt(myCipherText, key, "CAST5/ECB/ZeroBytePadding", "Base64")> -------------------------------------------------- myClearText should be the decrypted data. Hope it works for you. -tom- J W wrote: > BTW Dyncrypto is is the third party object. > > On 8/30/07, J W <[EMAIL PROTECTED]> wrote: >> Tom, >> >> Got a real interesting part here.
