MD5

This command will return a base64-encoded MD5 message digest for the given text. This can be used to encrypt the answer to your riddles so that "curious" immortals cannot use build commands to determine the answers to your area's riddles. For example:

md5 crystal ball
The code is: 6GI1Cf2L5hfcuqG+lJ4sog==
rb room javascript say '*' .
if ( event.text.md5() == '6GI1Cf2L5hfcuqG+lJ4sog==' )
  actor.msg( "That's the correct answer!" );
else
  actor.msg( "That is not the correct answer." );

Note that the answer to your riddle is encoded in the behavior. So even if an immortal examines your room's code, they will still not get the answer.

Usually all builder commands are logged to help ensure and catch immortal cheating when it happens. However, the md5 command is never logged.

This command is called "md5" because it uses the Message Digest version 5 encryption algorithm.
