MD2/MD4 Hash

MD2 (RFC 1319): 128-bit message digest by Ronald Rivest, used in legacy X.509 certificates. Engine: js-md2, OpenSSL-compatible.

MD4 (RFC 1320): 128-bit message digest, predecessor of MD5, common in NTLM and other legacy protocols. Engine: js-md4, OpenSSL-compatible.

What is MD2/MD4?

MD2 (RFC 1319) and MD4 (RFC 1320) are early 128-bit message digests by Ronald Rivest, predecessors of MD5.

Algorithms

  • MD2: RFC 1319, js-md2 engine.
  • MD4: RFC 1320, js-md4 engine.
  • Compatibility: OpenSSL-compatible output.

Key Features

  • Dual algorithm tabs with RFC labels.
  • Four outputs: 32/16-bit lower/upper hex.
  • 100% client-side.
