Generate cryptographic hashes of any text. Supports SHA-1, SHA-256, SHA-384, and SHA-512 algorithms using the Web Crypto API. Useful for checksums and data integrity verification.
A hash generator creates cryptographic hash values from text input using algorithms like SHA-1, SHA-256, SHA-384, and SHA-512. Hash functions transform any input into a fixed-length string of characters that serves as a unique digital fingerprint. Our tool uses the Web Crypto API built into your browser for secure, standards-compliant hash generation. Hashes are commonly used for data integrity verification, password storage, and digital signatures. Since all hashing happens locally in your browser, your sensitive data is never exposed to external servers.
A hash is a fixed-length string of characters generated from input data using a mathematical algorithm. The same input always produces the same hash, but it's practically impossible to reverse.
SHA-256 is the most commonly used for general purposes. SHA-512 provides extra security. SHA-1 is considered weak and should only be used for non-security checksums.
The Web Crypto API does not support MD5 natively due to its known vulnerabilities. We provide SHA-1, SHA-256, SHA-384, and SHA-512.
Yes. All hashing happens in your browser using the Web Crypto API. Your text is never sent to any server.
