Is there an encryption algorithm in ColdFusion that doesn’t use any special characters (only alphanumeric)? I have some data that I am passing to a user as a pseudo password which includes their username and the site that they are assigned to. I need to encrypt the string with an encryption algorithm built into ColdFusion 8 Enterprise edition and it cannot have any special characters in the final string. Is this possible and if so what algorithm will do this?
<cfset loc.token = encrypt(loc.token,Application.secretKey,'Blowfish','Base64') />
Just use binhex. Encode each byte as a hexadecimal number, ranging from 00 to FF. Base 64, however, includes several nonalphanumeric characters, such as + / = .
