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 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+":"+(string)nonce). This is important to know if you are calculating a hash in another language and wish to compare with one calculated in LSL.

LSL strings are stored in the UTF-8 format.

Examples

 
llSay(0, llMD5String("Hello, Avatar!", 0)); // returns 112abd47ceaae1c05a826828650434a6
 

Linux Example

$ echo -n 'Hello, Avatar!:0' | openssl md5
112abd47ceaae1c05a826828650434a6
