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+":"+(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.
Caveats
Examples
<lsl> llSay(0, llMD5String("Hello, Avatar!", 0)); // returns 112abd47ceaae1c05a826828650434a6 </lsl>
Linux Example
$ echo -n 'Hello, Avatar!:0' | openssl md5 112abd47ceaae1c05a826828650434a6
