The MD5 message-digest algorithm is a widely used hash function producing a 128-bit hash value. MD5 was designed by Ronald Rivest in 1991 to replace an earlier hash function MD4, and was specified in 1992 as RFC 1321.

What is Post Quantum Cryptography?

Tags: PQC, Cryptography

Post Quantum Cryptography (PQC), sometimes referred to as Quantum Proof, Quantum-Safe, or Quantum Resistant, is the development of cryptographic algorithms (usually public key algorithms) that are thought to be secure against a cryptanalytic attack by a quantum computer.
