If zcrypt fails to decrypt, strip away the zcrypt opcode Otherwise you can make a message look encrypted by sending it with a faked 'crypt' opcode. It also confuses the reply command. Replace it with 'failed-decrypt' just so it shows up in the UI somehow. Perhaps someone can write perl code to retry zcrypt on all messages with that opcode. Also has the side effect of marking gibberish so the user has some hope of realizing what happened if they sub to a zcrypted class without the key. And initialize out to NULL since there's actually a codepath where that value never gets set. Reported-by: Melissa Hunt <wings@mit.edu>
