Generador de hash
SHA-256, SHA-1, MD5
Sobre esta herramienta
Compute cryptographic hash digests (MD5, SHA-1, SHA-256, SHA-384, SHA-512) of text or files. Hashes are used for verifying file integrity (checksums on downloads), creating quick fingerprints, deduping content, and as building blocks in security systems.
Privvert uses the browser's built-in Web Crypto API for SHA-family algorithms (so they're as fast as any native tool) and a small library for MD5. Everything runs locally - sensitive content never leaves your machine.

Preguntas frecuentes
Not for security-critical use - both are vulnerable to collision attacks. They're still fine for non-security uses like file checksums and quick fingerprints. Use SHA-256 or SHA-512 for anything safety-critical.
SHA-256 is the modern default. Most projects publish a SHA-256 checksum next to their downloads.
Hash files individually. There's no standard 'folder hash' - different tools combine file hashes differently.
Make sure you're hashing the exact same bytes, with the same algorithm and the same encoding. Trailing newlines, BOMs, and CRLF vs LF line endings all change the hash.
SHA-256 is the default modern choice for anything that needs a strong fingerprint. MD5 and SHA-1 are fine for non-security uses like deduplication but are broken for any context where an attacker could craft a collision. SHA-512 is overkill for almost everything outside cryptography.
No. Hashes are computed by your browser's native crypto API. The input never leaves the page, so it's safe to hash passwords, API keys or other secrets for verification.
