FAQs
What is a hash function?
A hash function is a mathematical algorithm that converts input data of any size into a fixed-size string of characters, which is typically a hexadecimal number. Hash functions are designed to be one-way, meaning it's computationally infeasible to reverse the process.
Which hash algorithm should I use?
For security purposes, use SHA-256 or higher (SHA-384, SHA-512). MD5 and SHA-1 are considered cryptographically broken and should only be used for non-security purposes like checksums or data integrity verification.
Is my data secure when using this tool?
Yes, all hashing is performed locally in your browser using JavaScript. No data is transmitted to external servers or stored anywhere. Your input text never leaves your device.
Can I hash files with this tool?
This tool is designed for text input only. For file hashing, you would need specialized software or command-line tools that can read and process binary file data.
Why do I get the same hash for the same input?
Hash functions are deterministic, meaning the same input will always produce the same output. This property is essential for data verification and integrity checking.
What's the difference between MD5, SHA-1, and SHA-256?
MD5 produces 128-bit hashes, SHA-1 produces 160-bit hashes, and SHA-256 produces 256-bit hashes. Longer hashes are generally more secure. MD5 and SHA-1 have known vulnerabilities, while SHA-256 is currently considered secure.
