The Keyed-Hash Message Authentication Code (HMAC) standard (FIPS PUB 198-1) describes a mechanism for message authentication using cryptographic hash functions. HMAC can be used with a hash function in combination with a shared secret key. To see how to compute a MAC over the data, see FIPS...
cryptographic: certain hash functions such as Hashing#sha512 are designed to make it as infeasible as possible to reverse-engineer the input that produced a given hash code, or even to discover any two distinct inputs that yield the same result. These are called cryptographic hash functions. Bu...

The most popular language for implementing cryptography is C++ since it provides functions for complex arithmetic operations like exponentiation (used in RSA), working with large integers (used in Diffie–Hellman Key Exchange), hash functions (SHA256 and SHA512), etc., all while maintaining good ...

Rainbow table attacks—a rainbow table is a precomputed table for reversing cryptographic hash functions. It can be used to guess a function up to a certain length consisting of a limited set of characters. Reverse brute force attack—uses a common password or collection of passwords against many...
Those of us in the business think security is about cryptographic algorithms, whether Kerberos is a better choice than TLS or NTLMv2, the merits of WS*, whether password hashes should be salted, and all the other esoteric topics we love to discuss. Sure, we have a very different and ...
Windows includes self-testing features that ensure the integrity of executable program images and its cryptographic functions. Finally, Windows provides a trusted update mechanism to update Windows binaries itself. 1 This option is not included in the Windows Common Criteria evaluation. Microsoft ...
Windows also provides extensive auditing support of cryptographic operations, the ability to replace cryptographic functions and random number generators with alternative implementations,1 and a key isolation service designed to limit the potential exposure of secret and private keys. In additio...
