Hash Generator
Generate SHA-1, SHA-256, SHA-384 and SHA-512 cryptographic hashes from any text.
Input text
Cryptographic hash functions
A hash function maps any input to a fixed-size digest. Properties: deterministic, fast, one-way, collision-resistant. One bit change → completely different hash (avalanche effect).
- SHA-1: 160 bits — broken, avoid
- SHA-256: 256 bits — Bitcoin, SSL, passwords
- SHA-384: 384 bits — TLS 1.3, high-security APIs
- SHA-512: 512 bits — archives
What this tool does
Generates cryptographic hash digests of any text using SHA-1, SHA-256, SHA-384 and SHA-512. Hashes are one-way: the same input always produces the same hash, but the hash cannot be reversed.
Input fields explained
Input text
The text to hash. Any change — even one character or added space — produces a completely different hash. This is called the avalanche effect.
💡 Tips & context
→SHA-256 is the industry standard for integrity verification, digital signatures, and Bitcoin.
→Do NOT use SHA-1 for security-critical applications — it is considered weak.
→Hashes are used to verify file integrity: compare the hash of a downloaded file to the published hash.
Formula / How it works
SHA family: deterministic, one-way, collision-resistant. SHA-256 most widely used.
