The Digital Signature Algorithm (DSA) is a public-key cryptosystem and Federal Information Processing Standard for digital signatures, based on the mathematical concept of modular exponentiation and the discrete logarithm problem. In a public-key cryptosystem, a pair of private and public keys are created: data encrypted with either key can ...
A six-bit character code is a character encoding designed for use on computers with word lengths a multiple of 6. Six bits can only encode 64 distinct characters, so these codes generally include only the upper-case letters, the numerals, some punctuation characters, and sometimes control characters.

The Cryptographic Message Syntax (CMS) is the IETF's standard for cryptographically protected messages. It can be used by cryptographic schemes and protocols to digitally sign, digest, authenticate or encrypt any form of digital data.
Tamil All Character Encoding (TACE16) is a scheme for encoding the Tamil script in the Private Use Area of Unicode, implementing a syllabary-based character model differing from the modified-ISCII model used by Unicode's existing Tamil implementation.
In the signature schemes DSA and ECDSA, this nonce is traditionally generated randomly for each signature—and if the random number generator is ever broken and predictable when making a signature, the signature can leak the private key, as happened with the Sony PlayStation 3 firmware update signing key.
In cryptography, the simple XOR cipher is a type of additive cipher, [1] an encryption algorithm that operates according to the principles: . A 0 = A, A A = 0, A B = B A, (A B) C = A (B C),
The team used a new variation of the function field sieve for the medium prime case to compute a discrete logarithm in a Kummer extension field of 33341353 57 elements (a 1425-bit finite field). [ 26 ] [ 27 ] The same technique had been used a few weeks earlier to compute a discrete logarithm in a Kummer extension field of 33553771 47 elements ...
