Compute and verify MD5, SHA-1, and SHA-256 hashes
Enter text and optionally an expected hash to verify
Hash Checker is a free online tool that computes cryptographic hash values for text using MD5, SHA-1, or SHA-256 algorithms, and optionally verifies them against an expected hash. Hash functions are one-way functions that transform input data into a fixed-size string of characters. They are widely used for data integrity verification, password storage, digital signatures, and file verification. Enter your text, select an algorithm, and get the hash instantly. If you have an expected hash, paste it in and the tool will tell you whether the hashes match. All hashing is performed in your browser using the Web Crypto API.
