Simple, safe, data encryption

Introduction

Using the hottest encryption algorithm in the public domain Gozzip encrypts text and attachments from Windows or UNIX, by mouse or command-line. Email text is typically decrypted only for as long as it takes to read the message, securing each message not only in its open flight across the internet, but also in its final resting place.

Gozzip runs as a tray icon application on windows, and can be easily accessed using the Control-G hotkey. From any email package, simply select the text to encrypt, press control-G, and the easy to use gozzip console will pop up. Adding files to gozzip messages is trivial, either use the menus or drag and drop the files onto the gozzip message. Gozzip will even allow you to save messages back to .grt files, so any sensitive data, not just emails, can be protected in a gozzip file on your hard drive.

All gozzip messages are automatically compressed, encrypted and mime encoded before they are saved back into the email message.

The AES standard allows for up to 256 bit keys to be used to encrypt messages. The strength of the key is dependant on the strength of the password chosen. gozzip provides a visible password security rating which gives the user a level of confidence in the passwords that are used.

Hints can be added to messages, making it much easier for recipients to remember passwords, without resorting to yellow notes stuck to their monitors.

Gozzip is also available in a command line version for Windows and UNIX. Passwords can be saved in secure profile files, making batch encryption and automation easy.

What is the Advanced Encryption Standard (AES) ?

The Advanced Encryption Standard (AES) is a Federal Information Processing Standard (FIPS), specifically, FIPS Publication 197, that specifies a cryptographic algorithm for use by U.S. Government organizations to protect sensitive, unclassified information. NIST anticipates that the AES will be widely used on a voluntary basis by organizations, institutions, and individuals outside of the U.S. Government.

After an exhaustive search, NIST selected Rijndael as the AES algorithm (the algorithm's developers have suggested "Rain Doll" as a possible pronunciation). The two researchers who developed and submitted Rijndael for the AES are both cryptographers from Belgium: Dr. Joan Daemen (Yo'-ahn Dah'-mun) of Proton World International and Dr. Vincent Rijmen (Rye'-mun), a postdoctoral researcher in the Electrical Engineering Department (ESAT) of Katholieke Universiteit Leuven. Both have been very active in the cryptographic community.
