Cryptographic hash functions are programs that use a mathematical function, like an algorithm, to convert information to a hexadecimal form. These functions are also used in cryptocurrency to secure blockchain information and password protection. The comments, opinions, and analyses expressed on Investope...
Cryptographic hash functions are used to compute a fixed-size string based on any arbitrarily sized plaintext. The resulting hash value is called a “message digest,” or a “digital fingerprint.” Hash functions and the resulting values are used in various contexts (e.g., to compute the mes...
These constructions are called hash functions and play a very crucial role in the development of blockchain.Hash functionsHash functions are used to create fixed-length digests of arbitrarily long input strings. Hash functions are keyless, and they provide a data integrity service. They are ...

The use of either a hash-based MAC (HMAC) or block-cipher-based MAC is recommended as long as all underlying hash or symmetric encryption algorithms are also recommended for use; currently this includes the HMAC-SHA2 functions (HMAC-SHA256, HMAC-SHA384 and HMAC-SHA512)....
cryptographic hash functions to link blocks and secure transactions. While Bitcoin primarily uses SHA-256, some blockchain platforms and altcoins utilize SHA-512 for enhanced security and performance. Hash functions ensure the immutability and transparency of blockchain ledgers, making tampering virtually...

Design of Cryptographic protocols is distinguished by Block Cipher/Stream Cipher: MAC is a form of block cipher because it encrypts the whole message together. Digital Signatures also make use of hash functions based on block ciphers. Stream Ciphers encrypt one byte at a time. • Sender and ...
