How to use the Hash Generator
Enter any text and click Generate All Hashes. The tool computes MD5, SHA-1, SHA-256, and SHA-512 hashes instantly. All computation happens in your browser — your text never leaves your device.
Hash Algorithms Explained
- MD5 - 128-bit hash. Fast but not secure for passwords. Still used for file checksums.
- SHA-1 - 160-bit hash. Deprecated for security use. Used in git commits.
- SHA-256 - 256-bit hash. Part of SHA-2 family. Widely used in security applications.
- SHA-512 - 512-bit hash. Stronger variant of SHA-2. Used in SSL/TLS certificates.
Use Cases
Verify file integrity, hash passwords (use bcrypt in production), create message digests for blockchain, and check downloaded file authenticity.
FAQ
Is this secure?Yes, hashes are generated using the Web Crypto API. Your text never leaves your browser.
Can I reverse a hash?No, cryptographic hashes are one-way functions. You cannot reverse them to get the original text.
