utils.hash
Lua function

utils.hash

Summary

Hash a string, returning the hex codes

Prototype

s = utils.hash (s)


Description

Returns a 40-character hex string which is the hash of the string 's'. The string 's' may contain the null byte (ie. hex 00). Otherwise, this is the same behaviour as the world.Hash function.

eg.


print (utils.hash ("Nick Gammon")) --> fe09b07227a4e006213ac005831d55b20508a568
print (Hash ("Nick Gammon")) --> fe09b07227a4e006213ac005831d55b20508a568
