MD5 Hash Generator

Generate an MD5 hash from any text. Computed entirely in your browser using a pure JavaScript implementation — no server required.

About MD5

MD5 produces a 128-bit (16-byte) hash value, shown as a 32-character hexadecimal string. While it is no longer suitable for security-critical applications due to known collision vulnerabilities, it remains widely used for non-security purposes such as verifying file downloads and generating unique identifiers from input data.

This tool implements MD5 entirely in JavaScript — no data is sent to a server. The output matches the standard MD5 specification and is identical to the output of tools like the Linux md5sum command.

Frequently Asked Questions

What is MD5?

MD5 (Message-Digest Algorithm 5) is a widely used hash function that produces a 32-character hexadecimal digest from any input string. It was designed by Ronald Rivest in 1991 and is commonly used for checksums and data integrity verification.

Is MD5 secure for passwords?

No. MD5 is considered cryptographically broken and should not be used for password hashing or security-sensitive applications. Use bcrypt, Argon2, or scrypt for passwords, and SHA-256 or SHA-3 for general integrity checking.

What is MD5 still used for?

MD5 remains useful for non-security purposes such as file checksum verification, detecting duplicate files, and generating cache keys. Many download sites publish MD5 checksums alongside files so users can verify download integrity.

Does MD5 always produce the same output for the same input?

Yes. MD5 is deterministic — the same input will always produce the same 32-character output. The hash is computed purely from the input data.
