POCK
Application: Pock 2.00
Current Build: 2.00.00.0026 (updated 30-jun-2010)
Download: Zipped Installation (2.31Mb)
Installation System Requirements: Windows XP or Windows Vista

SUMMARY
Pock lets you send secret messages by email without using suspicious jumbled-up files.
Firstly, you and the receiver need to decide on a set of secret codes. You need to agree on a password, a codeword and an algorithm-phrase.

Codeword selector disk The password is a secret word, four characters of more.

The codeword is a 10 letter word. The receiver will be asked for three characters from the codeword to open the message. Instead of typing these letters in, the receiver picks them from a disc (shown right). The disc stops snoopers opening your secret messages by monitoring your keyboard strokes for passwords.

The algorithm-phrase creates the encryption algorithm that will encrypt and decrypt your message. The longer your algorithm word, the harder your message will be to crack, and the longer your encrypted message will be. See the Sandwich Encryption section for more details on combinative-algorithm encryption.

Once the message is encrypted it is converted into letters, with spaces, full stops, and paragraph breaks. When this message passes through an Internet firewall, the firewall will assume the message is a foreign language message. If the encrypted message was attached as a file to an email, it would be blocked by a firewall.

When the receiver gets the message, they copy and paste it into Pock, enter the password, enter three letters from the codeword, enter the algorithm-phrase, and the message is unwrapped.

Pock can only be used to send text messages. No files can be attached to a Pock message. No one could use Pock to send you a virus.
