Text Hash Generator (MD5, SHA-256, SHA-512) — Free
Runs 100% in your browser — your files never leave your device.
Checksums, file integrity, cache keys, puzzle solving — text hashing comes up constantly. Paste your text, pick from eight algorithms including MD5, SHA-1, SHA-256, SHA-512, SHA-3, and RIPEMD-160, and copy the digest as hexadecimal or binary. Everything is computed locally; your text is never sent anywhere.
How it works
- 1
Paste your text
Type or paste anything — the digests update as you type.
- 2
Pick an algorithm
Choose from MD5 to SHA-512, SHA-3, and RIPEMD-160.
- 3
Copy the digest
Grab the result in hex or binary with one click.
About this tool
What a hash is — and is not
A hash is a one-way fingerprint: the same input always produces the same output, but the output cannot be reversed into the input. Use it for file integrity checks, cache keys, deduplication, and puzzle problems — not for storing passwords (hashing for passwords needs a dedicated slow algorithm like bcrypt).
Which algorithm to pick
SHA-256 is the modern default; SHA-512 for longer digests; MD5 and SHA-1 only for legacy compatibility — both are broken for security purposes and exist here for checksums against old systems. RIPEMD-160 and SHA-3 cover the remaining standards-based cases.
Computed where your data stays
Everything runs in your browser: the text never leaves your device, which matters precisely because the things you hash — tokens, identifiers, sensitive strings — are things you would not paste into a random web service.
Frequently asked questions
Can a hash be reversed?
Not feasibly. Hash functions discard information by design — infinitely many inputs share any output. What attackers do is guess inputs and compare hashes, which is why long random inputs are safe and passwords are not.
Why do MD5 and SHA-1 exist here if they are broken?
For checksums and legacy verification against systems that still use them. Collisions (two inputs, same hash) have been demonstrated for both — never use them for anything security-critical.
What is the difference between hashing and encryption?
Hashing is one-way and keyless; encryption is two-way and keyed. You verify a hash; you decrypt ciphertext. The encryption tool covers the reversible case.
