llMD5String

	Security Warning!
	The MD5 hashing algorithm should not be used because it is too easy to generate collisions (two inputs which result in the same hash). http://www.kb.cert.org/vuls/id/836068

Summary

Function: string llMD5String( string src, integer nonce );

258	Function ID
0.0	Forced Delay
10.0	Energy

Returns a string of 32 hex characters that is the  MD5 checksum of src with a  salt of ":"+nonce.

• string	src
• integer	nonce

Specification

nonce is casted to string, then appended to src after a colon (src + ":" + nonce). This is important to know if you are calculating a hash in another language and wish to compare with one calculated in LSL. It could be written as MD5Hash(src + ":" + nonce)

The character encoding used by llMD5String is the UTF-8 format.
