Generate MD5, SHA-1, SHA-256 and SHA-512 hashes from any text, instantly in your browser.
Hash Generator computes cryptographic hash values from any text you enter. It calculates MD5, SHA-1, SHA-256 and SHA-512 all at once, so you can pick whichever algorithm your project needs. A hash is a fixed-length fingerprint of your input: changing even one character produces a completely different result. Everything runs locally in your browser using the Web Crypto API, so your text is never sent to any server.
A hash function always returns the same fixed-length output for the same input, and even a one-character change produces a completely different digest — which is what makes hashes useful for checksums, deduplication and integrity checks. They are one-way, so you cannot recover the original text from a hash. MD5 and SHA-1 are fast but cryptographically broken and should only be used for non-security checksums; SHA-256 and SHA-512 are the modern choices for anything security-sensitive. Note that hashing text on its own is not a safe way to store passwords — that needs a slow, salted algorithm such as bcrypt, scrypt or Argon2.

Yes. This tool is completely free with no signup, no limits and no watermarks.
For modern security use SHA-256 or SHA-512, as they are collision-resistant and widely trusted. SHA-1 and MD5 are faster but cryptographically broken, so use them only for checksums or legacy compatibility where security is not a concern.
No. Hash functions are one-way. The same input always produces the same hash, but you cannot reconstruct the input from the hash alone. That is what makes them useful for verifying data without exposing it.
No. All hashing happens entirely in your browser using the built-in Web Crypto API. Your text never leaves your device.
MD5 produces a 128-bit digest shown as 32 hex characters. SHA-1 produces 160 bits as 40 hex characters. SHA-256 produces 256 bits as 64 characters, and SHA-512 produces 512 bits as 128 characters. Longer digests are harder to find collisions for.
No. Encryption is reversible with a key; hashing is one-way and has no key. Hashing proves integrity or fingerprints data, while encryption keeps data secret and lets the right person read it back.
No. A single MD5 or SHA hash is too fast and can be brute-forced or looked up in rainbow tables. For passwords use a slow, salted password-hashing algorithm such as bcrypt, scrypt or Argon2. This tool is ideal for checksums, fingerprints and integrity checks rather than password storage.
No. The Hash Generator runs entirely in your web browser using the built-in Web Crypto API, so there is nothing to download or install.
