Types of Symmetric Encryption Algorithms. Algorithms for encrypting computer data come in two main varieties: symmetric and asymmetric. Each encryption type has inherent strengths and weaknesses.

What does encryption algorithm actually mean? Find out inside PCMag's comprehensive tech and computer-related encyclopedia.

The algorithm, sometimes referred to as “single DES” uses a 56-bit key to encrypt blocks of data, and can produce up to 72,000,000,000,000,000 unique keys.

The National Institute of Standards and Technology says the advent of massively parallel computing has rendered the Data Encryption Standard inadequate to protect federal government information.

The algorithm expands a single message by up to 8 bytes. DES is a block cipher that encrypts data in blocks of 64 bits. SAS Proprietary This provides basic fixed encoding encryption services on all ...

Karsten Nohl, the founder of Berlin's Security Research Labs, has announced an exploit for SIM cards using the outdated 56-bit DES algorithm for its signature verification. The security researcher ...

Microsoft is recommending using the Secure Hash Algorithm (SHA)256 encryption algorithm and AES (Advanced Encryption Standard) cipher instead, he said.

Microsoft removes DES encryption from Windows Microsoft has now announced that Cipher DES, which has long been considered insecure, will be removed from Windows in September.

Post-quantum encryption contender is taken out by single-core PC and 1 hour Leave it to mathematicians to muck up what looked like an impressive new algorithm.
