llMD5String | Does an MD5 message digest (a checksum basically). This can be used to verify authenticity without having to know the plaintext at all. |
llSHA1String | Does a SHA1 message digest (40 hexadecimal digits). More secure than MD5. |
llModPow | (a ^ b)%c Weak RSA encryption |
llBase64ToString | Decodes a Base64 string. This is not encryption, it is merely encoding. |
llStringToBase64 | Encodes a string. This is not encryption, it is merely encoding. |
Performs an xor on two Base64 strings. |
