Algorithms for encrypting computer data come in two main varieties: symmetric and asymmetric. Each encryption type has inherent strengths and weaknesses. Symmetric algorithms convert plain-text data ...

A proprietary algorithm developed by RSA Data Security, Inc., RC2 is an alternative to DES. The algorithm expands a single message by up to 8 bytes. RC2 is a block cipher that encrypts data in blocks ...

Cryptographic algorithms can be roughly classified in two categories: Encryption algorithms transform an input file into an output file from which it is (quite) impossible to recover the original ...

A formula used to turn ordinary data, or "plaintext," into a secret coded message known as "ciphertext." The ciphertext can reside in storage or travel over unsecure networks without its contents ...

The developers behind the Tor network have announced a major upcoming change. The free overlay network, which enables ...

Tor has announced improved encryption and security for the circuit traffic by replacing the old tor1 relay encryption algorithm with a new design called Counter Galois Onion (CGO).

In the last section we discussed the potential for optimizing algorithms, which can be done, but sometimes may not result in the type of performance required. As was mentioned, you can always move the ...

The mission of the US National Institute of Standards and Technology, NIST, is to create technical and measurement standards to make US manufacturing and industry more competitive. In 1987, the ...

Members can download this article in PDF format. In the last two articles, we covered the basic concepts and two basic types of cryptography. In this article, we will look at specific implementation ...
