MD5 Hash Generator
Legacy MD5 digests for checksums and lookups.
About this tool
MD5 produces a 128-bit digest and was the internet's default checksum for two decades. Collisions can now be produced in seconds, so MD5 is unsuitable for any security purpose — but it survives in file verification, cache keys, and countless legacy protocols.
This implementation runs in pure JavaScript in your browser; nothing you type is sent anywhere.
Like everything on encrypt.tools, this runs entirely in your browser — nothing you enter is transmitted or stored.
Frequently asked questions about MD5 Generator
Is MD5 secure?+
No — MD5 is cryptographically broken; collisions can be generated in seconds. Use it only for non-security purposes like legacy checksums, cache keys, and deduplication.
Why do people still use MD5?+
Speed and ubiquity. It survives in file verification, ETags, and countless legacy protocols where collision resistance isn't required.
Can MD5 be decrypted?+
No — MD5 is a one-way hash, not encryption. So-called MD5 'decrypters' are just databases of precomputed hashes for common inputs.
