Instead, use TEA or Blowfish, which are both reasonably fast. Tiny Encryption Algorithm is a very fast and moderately secure cipher produced by David Wheeler and Roger Needham of Cambridge ...

But what are these algorithms ... the cipher. The cryptosystems in wide use today have their origins in the 1970s, as modern electronic computers started to come into use. The Data Encryption ...

Public-key encryption, as noted in the ... i.e. "meet at the theater" for "fly to Chicago." Ciphers employ mathematical procedures called algorithms to transform messages into unreadable jumbles.

The goal of AES was not only to select a new cipher algorithm but also to dramatically increase both the block and key size compared with DES. Where DES used 64-bit blocks, AES uses 128-bit blocks.

In 1854, Sir Charles Wheatstone invented the cipher known as "Playfair," named for his friend Lyon Playfair, first Baron Playfair of St. Andrews, who popularized and promoted the cipher.

"Implementations MUST NOT negotiate cipher suites offering less than 112 bits of security, including so-called 'export-level' encryption (which provide ... is just not a good algorithm, no matter what ...
