http://livedocs.adobe.com/coldfusion/8/htmldocs/functions_e-g_01.html#1104201 Probably just a doc problem. Perhaps these HMAC algorithms weren't intended to be used in CF8. Many of the algorithms listed for Encrypt() are actually Hash() algorithms. For example: MD2, MD5, RIPEMD160, SHA1, SHA224, SHA256, SHA384, SHA512. These all work fine with the Hash() function, not with Encrypt(). HMACs are one-way functions, like hashes; but they use a secret key like block-encryption algorithms. The results of HMAC algorithms are short fixed-length values (like hashes) so they can not be decrypted back to the original text. HMACs can't work with the CFML Hash() function because there is no provision to pass the secret key. Curiously, you can apparently generate HMAC keys with GenerateSecretKey(). For example: GenerateSecretKey("HMAC", 128) or GenerateSecretKey("HMACSHA224", 64) The Public-key-cryptography algorithms: RSA, DSA, and Diffie-Hellman, don't seem to work with Encrypt() either. Since they need a matching pair of keys (public & private) it is likely that a new CF function would be needed to generate the keys. Something like GenerateKeyPair(algorithm, size). I noticed that two new undocumented Password-based-encryption algorithms (PBEs) are provided with the Enterprise (Trial) version: PBEWithSHA1AndDES and PBEWithSHA1AndRC2. -tom- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Get involved in the latest ColdFusion discussions, product development sharing, and articles on the Adobe Labs wiki. http://labs/adobe.com/wiki/index.php/ColdFusion_8 Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:285388 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
