Cryptographic primitives

These are the basic cornerstones of encryption, and consist of:

  • One-way hash function: A mathematical function that takes a variable-length input string and converts it into a fixed-length binary sequence.
  • Symmetric key cryptography: An encryption system in which the sender and receiver of a message share a single, common key that is used to encrypt and decrypt the message.
  • Public-key cryptography: Also known as asymmetric cryptography, a system that uses a pair of keys—a public key and private key.
