Hash Generator

Generate MD5, SHA-1, SHA-256, and SHA-512 hashes online. All hashing runs locally in your browser.

How to Use

Type or paste the text you want to hash into the input field. You can hash any text — passwords, file contents, API keys, or verification strings.
Select your hashing algorithm from the dropdown: MD5 (fast, 128-bit, now considered cryptographically broken), SHA-1 (160-bit, deprecated for security), SHA-256 (256-bit, widely trusted), or SHA-512 (512-bit, strongest option).
Click Generate and copy the resulting hash with one click. The hash is computed entirely in your browser — your input text is never sent to any server.

What's the difference between hashing and encryption?: Hashing is a one-way function — you can generate a hash from input but cannot reverse the hash back to the original text. Encryption is two-way — encrypted data can be decrypted with a key. Hashing is used for data integrity checks and password storage, while encryption is used for data confidentiality.
Which algorithm should I choose?: SHA-256 is the best all-around choice for most use cases — it's secure, widely supported, and produces a 64-character hex string. MD5 is fast but broken for security purposes (collisions can be engineered). SHA-1 is deprecated. Use SHA-512 when you need the highest security margin or 128-character output.
Does this tool support salt or pepper?: This tool generates raw, unsalted hashes of the exact input you provide. For password hashing with salt, use our Bcrypt Generator which automatically handles salting. If you need HMAC (keyed hashing), try our HMAC Generator.
