Frequently Asked Questions
What is Hash Generator used for?
Hash Generator creates fixed-size checksums from variable-length input, useful for verifying file integrity, storing password hashes, checking data transmission integrity, and generating unique identifiers. Each hash algorithm produces a deterministic output that changes completely with any modification to the input.
Which hash algorithms are supported?
The tool supports MD5, SHA-1, SHA-256, SHA-384, and SHA-512. MD5 and SHA-1 are considered legacy and should not be used for security purposes. SHA-256 is widely used for cryptographic applications, while SHA-384 and SHA-512 provide stronger security guarantees with longer hash values.
How do I verify file integrity with hashes?
Enter your file content or text into the input, click "Generate All Hashes" to see all algorithm outputs, then compare the hash with the expected value. Any change in the input, no matter how small, produces a completely different hash output. This makes hashes reliable for detecting tampering or corruption.
Is my data sent to a server?
No. All hashing uses the browser's Web Crypto API, which performs cryptographic operations entirely on your device. Your input data never leaves your browser, making this safe for hashing sensitive content like passwords or confidential documents.
What keyboard shortcuts are available?
Press Ctrl+Enter (or Cmd+Enter on Mac) while in the input field to quickly generate all hashes. This allows rapid verification workflows without switching to the mouse.
Can I reverse a hash to recover the original text?
No. Hashing is a one-way function by design. The fixed-length output cannot uniquely determine variable-length input, and there is no mathematical way to reverse the process. For password storage, use specialized password hashing functions like bcrypt or Argon2 that include salting and are designed to be slow.
