What is MD5?

MD5 (Message-Digest Algorithm 5) is a widely used cryptographic hash function that produces a 128-bit hash value. It is commonly used for checksums and verifying data integrity.

How MD5 Works

MD5 takes an input message and processes it through a series of mathematical operations to generate a fixed-length 32-character hexadecimal hash.

Why Use MD5?

MD5 is often used for:

  • Verifying file integrity.
  • Generating unique identifiers.
  • Basic checksums in non-security applications.

Limitations of MD5

Despite its popularity, MD5 is considered weak for security purposes due to vulnerabilities in collision resistance. It is not recommended for cryptographic security applications.
