Password Pair

Password Pair Publisher's Description:
Password Pair allows you and a distant associate to establish an identical long and complex password that you can use to encrypt and decrypt files. You may then transfer the encrypted file securely over the Internet. Password Pair uses a "Handshake" technique similar to that used in your web application when you have a secure link to a bank, for example. Through an exchange of numeric messages (two each way) over an Instant Messaging program or eMail, you and an associate can produce a common password on your separate computers. Any third party recording the numeric traffic between you and your associate will not be able to deduce your password without massive computer help and know-how to reverse engineer Password Pair. It would not be as difficult as a "brute force" attack on your encrypted file's password itself, but. It would be dramatically more difficult than a "brute force" attack on passwords such as short, simple word and number passwords. My best estimate is a low end difficulty level of 1.36521010474993 E+138 attempts, or more, on a 128 character password generated by Password Pair.
