Generate SHA-1, SHA-256, and SHA-512 cryptographic hashes from any text input.
Frequently Asked Questions
This tool generates SHA-1, SHA-256, and SHA-512 hashes using the browser's built-in Web Crypto API. These are industry-standard cryptographic hash functions.
MD5 is not available in the Web Crypto API. It is also considered cryptographically broken and unsuitable for security purposes. SHA-256 is the recommended replacement.
No. Cryptographic hash functions are one-way functions. You cannot derive the original input from a hash. This is by design and is what makes hashes useful for password storage and data integrity verification.
SHA-256 is widely used for data integrity verification, digital signatures, password hashing (when combined with a salt), blockchain (Bitcoin uses SHA-256), and certificate validation.
Yes. All hash computation happens locally in your browser using the Web Crypto API. No data is sent to any server.
