Preforms a SHA-2 Hash on the text. Similar to and MD5 hash, although (slightly) more secure. Two versions of the function are provided, one for UTF-8 Strings (all strings in LSL are UTF-8) and the other is for Base64 Strings (you need to tell it how many bits long the data is).
{{LSL New}} LSL now includes the function [[llSHA256String]].

 NEW  LSL now includes the function llSHA256String.

Performs an SHA-2 Hash on the text. Similar to an MD5 hash, but (slightly) more secure. Two versions of the function are provided, one for UTF-8 Strings (all strings in LSL are UTF-8) and the other is for Base64 Strings (you need to tell it how many bits long the data is).

View "Wikipedia logo" SHA-2 for more information.
