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 |

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