FAQ - Frequently Asked Questions

What is MD4?

MD4 (Message Digest Algorithm 4) is a cryptographic hash function developed by Ronald Rivest in 1990. It produces a 128-bit (16-byte) hash value, typically rendered as a 32-digit hexadecimal number.

Is MD4 Secure?

MD4 is considered cryptographically broken and unsuitable for further use. It has been found vulnerable to various attacks, including collision and preimage attacks. For secure applications, stronger hash functions like SHA-256 or bcrypt are recommended.

Hash Details

The MD4 hash consists of 32 hexadecimal characters, representing 128 bits of data. Each character is in the range of 0-9 and a-f.

  • Length: 32 hexadecimal characters (128 bits)
  • Output Format: Typically displayed as a 32-character hexadecimal string.
  • Speed: MD4 is designed to be fast, which makes it vulnerable to brute-force attacks.

Example Explained: Consider the MD4 hash 1bee69a46ba811185c194762abaeae90. This hash is structured as follows:

  • Hash Value: 1bee69a46ba811185c194762abaeae90

What is Password Hashing?

Password hashing is a security technique used to transform a password into a fixed-size string of characters, which is designed to be impossible to reverse. It helps protect the password's original text while verifying user credentials without storing the actual password.

What is the Password Hashing Competition?

The Password Hashing Competition (PHC) was a project aimed at identifying new, secure, and efficient password hashing schemes to improve password storage security. It encouraged the development and review of hashing algorithms to withstand advances in hacking techniques.
