WebMar 1, 2024 · Blockchains make use of two types of cryptographic algorithms, asymmetric-key algorithms, and hash functions. ... 256, 384, and 512 bits. SHA-2 is a widely used standard in modern cryptographic applications. Bitcoin uses the SHA-256 variant as a hashing algorithm to solve proof-of-work puzzles. SHA-3 is the latest family of functions … WebTo decrypt the message, the private key is used to decode the encoded message. Hash-based cryptography is another PQC system that is based on the collision resistance of cryptographic hash functions. The security of hash-based cryptography is based on the fact that it is computationally difficult to find two messages that have the same hash value.
