Frequently asked questions about the Hash Generator
Everything about cryptographic hash functions
A cryptographic hash is a one-way function that converts arbitrary input into a fixed, unique string (the "digest"). Even the smallest change in the input text produces a completely different hash. Hashes are irreversible — you cannot reconstruct the original text from the hash.
For security applications (passwords, digital signatures), we recommend SHA-256 or SHA-512. SHA-3 is the most modern option. MD5 and SHA-1 are considered cryptographically broken and should only be used for checksums (e.g. file integrity verification), never for passwords.
No. All hash calculations happen exclusively in your browser. No network request is made. Your text never leaves your browser at any point — ideal for sensitive data.
The digest (the hash result) is a sequence of bytes. These can be represented in different ways: Hexadecimal (0-9, a-f) is the most common format and twice as long as the raw data. Base64 is more compact and better suited for URLs or emails. Both representations encode the exact same hash.
Hash functions are used for: password storage (never plaintext!), file integrity verification (checksums), digital signatures, blockchain technology, Git commit IDs, API request authentication (HMAC) and data deduplication.
