llMD5String
string llMD5String(string Text, integer Nonce)Returns a string of 32 hex characters that is an RSA Data Security Inc., MD5 Message-Digest Algorithm of Text with Nonce used as the salt.
Returns a 32-character hex string. (128-bit in binary.)
Parameters
-
Text(string) -
Nonce(integer)
Security Warning: The MD5 hashing algorithm should not be used because it is too easy to generate collisions (two inputs which result in the same hash). See CERT Advisory.
Technical Details
Section titled “Technical Details”The nonce is cast to a string and appended to the source after a colon. The formula is:
MD5Hash(src + ":" + nonce)This is important to know if you are calculating a hash in another language and wish to compare with one calculated in LSL.
The character encoding used by llMD5String is UTF-8.
Examples
Section titled “Examples”llSay(0, llMD5String("Hello, Avatar!", 0)); // returns 112abd47ceaae1c05a826828650434a6Comparison with Linux
Section titled “Comparison with Linux”You can verify LSL MD5 hashes using the command line:
$ echo -n 'Hello, Avatar!:0' | openssl md5112abd47ceaae1c05a826828650434a6Note the nonce is appended after a colon, matching the LSL behavior.
