VB Script; 6 Comments. MD5 Hash Calculator. MD6 Hash Calculator. (Note: It is possible to encrpyt the data multiple times, even with different passwords on each iteration. MD4 Hash Calculator. RC4 is generally regarded as being "strong", and has no known attacks (although a relatively weak class of keys has been identified - the discussion of which is beyond the scope of this document). aes-256-cbc-hmac-sha1. Applications that call in to SChannel directly will continue to use RC4 … var decrypted = CryptoJS.RC4.decrypt({ ciphertext: CryptoJS.enc.Base64.parse(encrypted) }, CryptoJS.enc.Latin1.parse(theKey)); JSEncrypt returns a "plain string" from the crypt.decrypt() function, which means that it has to be either parsed with Latin1 or UTF-8 encoding in mind.
