I took a quick look at the code of the ssh/telnet mp on trunk and have 
two suggestions.

I can see that you are using DES and that the encryption key is 
hardcoded. DES is easily bruteforceable, you might want to switch to AES 
256bits. The encryption key should be set by the administrator and put 
in the config file, otherwise someone can just get the encrypted 
password from the source code that is publicly available to decipher it.

But I don't think this type of information should be registered to the 
LS anyways.
