About

An MD5 hash generator takes any text and produces a fixed 32-character hexadecimal fingerprint using the MD5 algorithm. Developers use MD5 hashes to verify file integrity, compare data without exposing originals, and generate cache keys or ETags. This free tool runs entirely in your browser — no data is ever sent to a server — and updates the hash live as you type.

FAQ
What is an MD5 hash?+

MD5 (Message Digest 5) is a cryptographic hash function that converts any input — a word, a sentence, or an entire file — into a fixed 128-bit (32 hex character) digest. The same input always produces the same hash, but even a single character change produces a completely different result.

Is MD5 safe for passwords?+

No. MD5 is considered cryptographically broken for security-sensitive uses like password storage because it is fast to compute and vulnerable to collision and preimage attacks. Use bcrypt, Argon2, or SHA-256 for passwords. MD5 remains widely used for non-security purposes such as checksums and data deduplication.

Why does this tool not use the browser's built-in SubtleCrypto API?+

The Web Cryptography API's SubtleCrypto interface does not support MD5 — only SHA-1, SHA-256, SHA-384, and SHA-512. This tool implements the full MD5 algorithm in pure JavaScript, verified against the RFC 1321 test vectors, so it works offline and without any external dependencies.

What output formats are available?+

You can choose between lowercase hexadecimal (the most common format, e.g. 65a8e27d…), uppercase hexadecimal (e.g. 65A8E27D…), and Base64 encoding of the raw 16-byte digest. The batch mode lets you hash multiple values at once, one per line.
