Can you really decrypt MD5?

No. MD5 is a one-way hash function, so it cannot be mathematically reversed. This tool only recovers values by looking them up in a dictionary of common words, passwords and numbers — the same way every online "MD5 decrypter" works.

Why didn't my hash decrypt?

If the original text wasn't a common word, password or number, it won't be in the lookup table, so no match is found. That's expected behavior for MD5.

Yes. Both hashing and the reverse lookup run entirely in your browser. Nothing you type is sent to a server.

Is MD5 safe for passwords?

No. MD5 is fast and has known weaknesses, which makes hashed passwords easy to crack. Use a salted, slow algorithm such as bcrypt, scrypt or Argon2 instead.

MD5 Encrypt & Decrypt

Hash text to MD5, or reverse-look-up common MD5 hashes back to their original value.

Output

What Is the MD5 Encrypt & Decrypt?

The MD5 Encrypt & Decrypt tool turns text into an MD5 hash and attempts to reverse common MD5 hashes back to their original text. MD5 is a one-way cryptographic hash, so true decryption is impossible — instead, the "decrypt" mode performs a reverse lookup, hashing a dictionary of common words, passwords and numbers in your browser and checking for a match. Everything runs locally, so nothing you enter is uploaded.

How It Works

Pick a mode. In Encrypt mode, type or paste text (one item per line) and the 32-character MD5 hash appears instantly. In Decrypt mode, paste one or more MD5 hashes and click Look Up Hash — the tool compares each hash against its in-browser table of common values and shows any matches. Copy or download the results with one click.

When to Use It

Use Encrypt mode to generate MD5 checksums or digests for testing, deduplication or legacy systems. Use Decrypt mode to recover the original value behind a hash when it's likely a common word, password or number. For anything security-sensitive, prefer a modern algorithm like SHA-256 with a salt — MD5 is not considered secure for passwords.
