Simple, safe, data encryptionIntroduction
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
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. Platforms Supported
Gozzip is free for home and non-commercial use and contains no
time-restrictions, crippleware or annoyware. Commercial users may test
Gozzip for 30 days before registering.
