2013-3-16 · To summarize, we believe that SHA-3 must exhibit great performance on as wide a range of commodity processors as possible, and should exploit the current Moore’s law trend towards parallelism. A very large number of applications use HMAC-SHA1 or HMAC …

2015-8-4 · : SHA-3 Standard: Permutation-Based Hash and Extendable-Output Functions (FIPS PUB 202). 2. Category of Standard: Computer Security Standard, Cryptography. 3. Explanation: This Standard (FIPS 202) specifies the Secure Hash Algorithm-3 (SHA-3) family of functions on binary data. Each of the SHA-3 functions is based on an instance of the K MD5、SHA-1、HMAC、HMAC-MD5和HMAC … 2002-12-30 GitHub - Akagi201/hmac-sha1: Standalone implementation … Standalone implementation of `HMAC()` + `EVP_sha1()` in `OpenSSL` - Akagi201/hmac-sha1

Provides a Racket interface to the OpenSSL implementation of SHA-1 and SHA-2. SHA-2 includes four flavors: SHA-224, SHA-256, SHA-384, and SHA-512. Hashing is based on a one-way mathematical function; functions that are easy to compute, but significantly tough to reverse. Hash functions are the basis of the protection mechanism of Hashed Message Authentication Codes (HMAC). It is a major enabling technology for network security used to achieve specific security objectives. For the four SHA-3 candidates where the digest length is fixed, the input block length is assumed to be the bitrate r and the output length is the digest length of the candidate. where the bitrate is the permutation size (1600 bits / 200 bytes) - capacity (2x digest size for SHA-3 / Keccak). For example, SHA-256 operates on 512-bit blocks. The size of the output of HMAC is the same as that of the underlying hash function (e.g., 256 and 1600 bits in the case of SHA-256 and SHA-3, respectively), although it can be truncated if desired. HMAC does not encrypt the message.
