Encryption is a process that modifies information in a way that makes
it unreadable until the exact same process is reversed.
You enter a secret key; it then garbles the contents of files with
lightning speed and then renames the files to random numbers while keeping
the real names internally. The files can only be viewed when decrypted
using the exact same key.
Private Encryptor™ offers 4 different encryption schemes:
- Stealth Media - An algorithm developed specially for large media
files, images, video and executables. These files are encrypted by
short bursts of random numbers optimized for speed but still providing
- Fast Encryption - A fast general purpose encryption based on a
sequence of random numbers that is as long as the input file.
- DES - In 1972 the National Bureau of Standards (NBS) asked for
proposals to encrypt commercial computer data traffic (just like the
data in your PC today). In 1974, the NBS asked the National Security
Agency (NSA) for assistance. One of NSA's primary functions is the
development and breaking of data protection techniques (codes and
ciphers). An algorithm developed by IBM became the Data Encryption
Standard (DES) and was issued by the National Bureau of Standards in
1977, providing an approved and secure standard for protecting
computer data against possible theft or unauthorized access. The
designers of the DES algorithm maintain that the time needed to
decrypt a DES encrypted file makes it unprofitable to use trial and
error techniques as it has 72 quadrillion possible key combinations.
Blowfish - a symmetric block cipher that can be used as a
drop-in replacement for DES or IDEA. It takes a variable-length key,
from 32 bits to 448 bits, making it ideal for both domestic and
exportable use. Blowfish was designed in 1993 by Bruce Schneier as a
fast, free alternative to existing encryption algorithms. Since then
it has been analyzed considerably, and it is slowly gaining acceptance
as a strong encryption algorithm.
In addition you can get the Strong
Encryption Package and add the following strongest encryptions
The Data Encryption Standard (DES)
was developed by an IBM team around 1974 and adopted as a national
standard in 1977. Triple DES is a minor variation of this standard. It
takes a 192 bit key (24 characters) as input and breaks it into three
keys. First, DES is used to encrypt a file using the first key. Then the
file is decrypted using the second key. The final step is to encrypt the
file again using the third key. Note that if all three 64 bit keys are the
same, Triple DES is identical to regular DES. However, if used correctly,
this method of encryption is much more secure than regular DES. The
key size is 192 bits (24 characters).
Blowfish 448 bits
Blowfish is a symmetric block cipher
that can be used as a drop-in replacement for DES or IDEA. Blowfish was
designed in 1993 by Bruce Schneier as a fast, free alternative to existing
encryption algorithms. Since then it has been analyzed considerably, and
it is slowly gaining acceptance as a strong encryption algorithm. The
key size can range from 32 bits (4 characters) to 448 bits (56
The Twofish block cipher is
Counterpane Systems's candidate for the new Advanced Encryption Standard (AES).
It is one of the five finalists chosen by NIST from a field of 15
candidates. Twofish is designed to be highly secure and highly flexible.
Counterpane Systems has spent over one thousand hours cryptanalyzing
Twofish, and has found no attacks that go anywhere near to breaking the
cipher. The key size is 256 bits (32
MARS is a block cipher designed by
IBM as a candidate algorithm for the Advanced Encryption Standard (AES).
It has been selected as one of the five finalists in the AES competition.
MARS is unique in that it combines virtually every design technique known
to cryptographers in one package. It uses two entirely separate
algorithms, so that even if one portion of MARS is broken the rest of the
cipher will remain secure and data will still be safe. Due to its design,
MARS offers better security than triple DES while running significantly
faster than single DES. The combination of high security, high speed, and
flexibility makes MARS an excellent choice for the encryption needs of the
information world well into the 21st century. The
key size is 448 bits (56 characters).
AES-Advanced Encryption Standard (Rijndael)
Rijndael is a block cipher designed
by Joan Daemen and Vincent Rijmen as a candidate algorithm for the
Advanced Encryption Standard (AES). It has been selected as one of the
five finalists in the AES competition. The design of Rijndael was strongly
influenced by the design of the block cipher Square. Like all AES
finalists, Rijndael is highly secure and has undergone extensive
cryptanalysis. No weaknesses have been found. The
key size is 256 bits (32 characters).
Serpent was designed by Ross
Anderson, Eli Biham and Lars Knudsen as a candidate for the Advanced
Encryption Standard. It has been selected as one of the five finalists in
the AES competition. Serpent is faster than DES and uses a simpler, more
secure algorithm. Like Skipjack, there are no known shortcut attacks that
can break this algorithm. Serpent's designers maintain that it should be
at least a century before a brute force attack becomes feasible. The
key size is 256 bits (32 characters).
Skipjack is a formerly secret NSA
encryption algorithm that was declassified in 1998. It was used to encrypt
sensitive, but not classified, government data. It has been extensively
cryptanalyzed, and has no weaknesses. There are no known shortcut attacks
that can break Skipjack, making it one of the strongest encryption
algorithms available to civilians today. The NSA estimates that a brute
force attack would cost approximately $1.2 billion and will not be
feasible for at least 40 years. The
key size is 80 bits (10 characters).
Due to export restrictions, the Strong Encryption cannot be sold to
the following countries:
Cuba, Iran, Iraq, Libya, North Korea, Sudan and Syria.
