A Hash Function Encryption Algorithm is a Data Cryptographic Algorithm that uses a fixed length hash value instead of using a key.
- AKA: Message Digest, One-Way Encryption Algorithm, Hash Encryption Algorithm.
- Context:
- It can be implemented by a Hash Function Encryption System to solve a Hash Function Encryption Task.
- Example(s):
- Counter-Example(s):
- See: Hash Function, SSH, Data Transformation Algorithm, Public Key Infrastructure (PKI), Cryptosystem, Cold Boot Attack, Cyberspace Electronic Security Act, Geoblocking, Data Erasure, Information Security, Decentralized Online Social Network.
