Hash Generator
Compute SHA-1, SHA-256, SHA-384, and SHA-512 checksums for text or files. All hashing happens locally using the Web Crypto API.
Type text or upload a file to compute checksums
About This Tool
Hash Generator produces SHA-1, SHA-256, SHA-384, and SHA-512 cryptographic hashes from any text input. Hashes are one-way functions - the same input always produces the same hash, but the hash cannot be reversed.
Common uses include verifying file integrity (checksums), storing passwords securely (as salted hashes), generating unique identifiers, and digital signatures. SHA-256 is the most widely used for general-purpose hashing.
All hashing uses the Web Crypto API built into modern browsers. No server call needed. Results update in real time as you type.
