• 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
