Frequently Asked Questions
What is a cryptographic hash?
A cryptographic hash is a fixed-length string of characters generated from input data using a one-way mathematical function. Even a tiny change in the input produces a completely different hash, making it useful for verifying data integrity.
What is the difference between SHA-1, SHA-256, and SHA-512?
They produce different length outputs: SHA-1 generates 160-bit hashes, SHA-256 generates 256-bit hashes, and SHA-512 generates 512-bit hashes. SHA-256 and SHA-512 are considered more secure than SHA-1, which has known vulnerabilities.
Can I hash files with this tool?
This tool hashes text input. For file hashing, you can copy the file's text content into the input field. For binary files, you may need a dedicated file hashing tool.
Is my input data sent to any server?
No. All hash generation happens locally in your browser using the Web Crypto API. Your text is never transmitted or stored.
Which hash algorithms does this tool support?
This tool supports SHA-1, SHA-256, SHA-384, and SHA-512. SHA-256 is the most commonly used and recommended for general purposes. SHA-512 provides the strongest security for sensitive data.
