Hash calculator
Calculate a SHA digest of UTF-8 text in your browser. Choose SHA-256, SHA-384, SHA-512 or legacy SHA-1 and copy the hexadecimal hash.
Features
- Hash text with SHA-256, SHA-384, SHA-512 or SHA-1.
- Encode the input as UTF-8 before hashing.
- Return the digest as a hexadecimal string.
How to use this tool
- Paste the text to hash.
- Select the algorithm and start processing.
- Copy or download the hexadecimal digest.
Good to know
This tool is free without sign-up, with unlimited processing and exports within the displayed input limits.
- Whitespace changes the hash. A plain SHA digest is not a password-storage scheme; SHA-1 is included for legacy compatibility.
