What is an MD5 Hash?

MD5 (Message-Digest Algorithm 5) is a widely-used cryptographic hash function that produces a 128-bit (16-byte) hash value. Commonly used for data integrity verification, including file validation and password storage. While MD5 has known collision vulnerabilities, it remains popular in non-security-critical applications.

What is an SHA1 Hash?

SHA-1 (Secure Hash Algorithm 1), designed by the NSA, generates a 160-bit (20-byte) hash value. Once widely used in SSL certificates and Git version control systems. Since 2017, SHA-1 has been considered vulnerable to collision attacks, and it's recommended to use stronger algorithms like SHA-256 or SHA-3 for security-sensitive applications.
