SHA-2
| LSL Portal | Functions | Events | Types | Operators | Constants | Flow Control | Script Library | Categorized Library | Tutorials |
Preforms a SHA2 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).
