要約
関数: string llSHA256String( string src );
仕様
LSL strings are stored in the UTF-8 format.
警告
There's no way to input a zero-byte value into this function, nor any byte value from 128-255, therefore it's currently broken for many purposes (like HMAC-SHA1). The reason is because LSL strings cannot have a unicode null character (U+0000) in them, and LSL has no escape code for the null character (many programming languages use \0 but LSL does not have this feature). llEscapeURL("%00") yields an empty string. As well, inside this function, each character with a Unicode integer value over U+0127 / 007F are dealt with in UTF-8 fashion: in the hex values, 0xC2 is prepended to the byte value (hence 0x0080-0x00FF become 0xC280-0xC2FF inside the llSHA256String() routine).
サンプル
llSay(0, llSHA256String("Hello, Avatar!")); // returns 3a9f9d2e4360319a62139d19bd425c16fb8439b832d74d5221ca75b54c35b4f2
Linux Example
$ echo -n 'Hello, Avatar!' | openssl sha256 3a9f9d2e4360319a62139d19bd425c16fb8439b832d74d5221ca75b54c35b4f2

特記事項
Prior to this, the only way to get the SHA-256 hash was to use the LSL SHA-256 port: SHA-2
