Output:
All processing happens in your browser. No data is sent to any server.
- Paste your text in the input box above
- Select a hash algorithm (SHA-1, SHA-256, SHA-384, or SHA-512)
- Choose output format — Hex (lowercase hexadecimal) or Base64
- Click Generate Hash to compute the hash
All processing happens in your browser using the Web Crypto API — nothing is sent to any server.
Which algorithm should I use?
SHA-256 is the most commonly used. SHA-1 is considered weak for security purposes but is still used for checksums. SHA-384 and SHA-512 offer longer output for higher security requirements.
Is my data safe?
Yes. This tool uses your browser's built-in Web Crypto API. Your data never leaves your device.
Why is MD5 not included?
MD5 is cryptographically broken and not supported by the Web Crypto API. It should not be used for security purposes. Use SHA-256 or stronger instead.
