Hash Generator (MD5, SHA-256)

Type or paste text into the box, or switch to File and choose a file. The MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes are calculated at the same time and can be copied as lowercase hex, uppercase hex or Base64.

No. Files are read and hashed locally in your browser. SHA hashes use the browser's built-in Web Crypto API and MD5 uses a small JavaScript implementation included in the page. The file size limit is 512 MB because the whole file is read into memory.

Choose the downloaded file, then paste the checksum published by the vendor into the Compare field. The tool checks it against every computed hash, ignoring letter case and spaces, and tells you which algorithm matched or that nothing matched.

Hashes change if even one byte changes. Common causes are a trailing newline, different line endings (Windows CRLF versus LF), extra spaces, or a different text encoding. This tool hashes text as UTF-8, and line breaks typed into the text box are hashed as LF.

No. Practical collision attacks exist for both, so they should not be used for digital signatures, certificates or password storage. They remain fine for non-adversarial checksums. Use SHA-256 or SHA-512 for integrity checks that matter, and a dedicated password hashing algorithm such as Argon2, bcrypt or scrypt for passwords.

No. Hash functions are one-way. The only way to find an input for a given hash is to guess inputs and compare, which is why short or common strings can be found in lookup tables. That is also why plain hashes are not suitable for storing passwords.
