Compute MD5 hashes from text, for checksums
MD5 Hash Generator is a simple online tool for computing the MD5 hash of a text string. MD5 is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash, usually shown as a 32-character hexadecimal string.
Because everything runs locally, nothing is uploaded — which matters when the string you are hashing is a password, a token, or anything else you would rather not paste into someone's server. MD5 is a checksum tool, not a security measure: read what an MD5 hash is and why it isn't encryption before relying on it for anything sensitive.
Convert plain text to an MD5 hash for checksums, password hashing, and more.
Copy the MD5 hash with one click and paste it into other applications.
Everything runs locally and nothing is uploaded, keeping your data secure.
Works well on phones, tablets, and desktops with responsive layouts for every screen size.
MD5 is a cryptographic hash function that turns any input into a fixed 32-character hexadecimal digest, always the same length no matter the input size.
No. MD5 is fast and now considered broken for security purposes. Use a slow, salted algorithm like bcrypt or Argon2 for passwords. MD5 is still fine for checksums and detecting file changes.
Hashing is deterministic: identical input always produces the identical digest. That's exactly what makes it useful for verifying that data hasn't changed.
No. The digest is computed locally, so whatever you paste 鈥?a password, a token, a key 鈥?stays on your device.
