In the hexadecimal character set, case is non-significant (e.g. 'A3' is equivalent to 'a3'). Consider specifying hex colors in CSS.
The canonical representation of an MD5 hash (or any other hash) is a big ol' list of bits, not a string. The string is just an encoding of those bits into hex. Since hex is not case-sensitive, there is no difference between an uppercase and a lowercase encoding of the hash. If, however, you care about the encoded version in a case sensitive manner, then you need to supply that semantic yourself. There's no way that the hash algorithm could possibly do it for you. cheers, barneyb On Thu, May 1, 2008 at 1:12 PM, Jim McAtee <[EMAIL PROTECTED]> wrote: > CF's hash() function returns its output hex string with uppercase letters. > Generally not a problem if you only apply a single hash to a string, but > if you need to do multiple hashes, then the final outcome is unlikely to > match that of many other applications that use lower case hexadecimal > digits.
