About Hash Generator (MD5, SHA-256...)
Cryptographic Hashes Explained
A cryptographic hash function takes an input (or 'message') and returns a fixed-size string of bytes. The string is typically a 'digest' that looks like random text. They are used extensively in information security to verify data integrity.
Available Algorithms
- SHA-1: An older algorithm producing a 160-bit hash. No longer considered secure against well-funded attackers, but still used for basic checksums.
- SHA-256: Part of the SHA-2 family. Produces a 256-bit hash. Extremely secure and used in Bitcoin and SSL certificates.
- SHA-384 / SHA-512: Larger variants of the SHA-2 family providing even greater cryptographic security.
All generation happens entirely in your browser using the native Web Crypto API.
Frequently Asked Questions
Are my texts sent to a server to be hashed?
No. The hashing happens entirely in your browser using the native Web Crypto API. Your text is never transmitted over the internet.
