How to Use
- 1 Choose Encrypt to generate an MD5 hash, or Decrypt to look up a hash.
- 2 Enter your text or MD5 hash in the input box.
- 3 Click the Encrypt or Decrypt button to process.
- 4 Copy the result using the Copy button.
Use Cases
Verify that a password is stored as an MD5 hash by encrypting the plaintext and comparing the output.
Generate an MD5 checksum for a text string to verify data integrity across systems.
Check whether an MD5 hash in your database corresponds to a known plaintext value.
Analyze MD5 hashes during penetration testing or security audits to assess password strength.
FAQ
MD5 (Message Digest Algorithm 5) is a one-way cryptographic hash function that produces a fixed 32-character hexadecimal string from any input. It is widely used for checksums and legacy password storage.
MD5 is mathematically irreversible — you cannot derive the original text from a hash alone. Decryption works by searching a large database of known hash-to-plaintext pairs (rainbow tables). If the original text was uncommon or complex, it may not be found.
No. MD5 is considered cryptographically broken and should not be used for password storage in modern systems. Use bcrypt, Argon2, or SHA-256 instead.
The lookup database only contains hashes of known words and common strings. If the original input was a random or complex string, it will not be in the database.
Encryption is performed entirely in your browser — your text never leaves your device. Decryption sends only the MD5 hash (not your original text) to a lookup service.
The free lookup service allows up to 100 queries per day. If the limit is reached, try again the following day.
