Frequently Asked Questions
What is a cryptographic hash?
A hash is a one-way mathematical function that turns any input (text or file) into a fixed-length string of characters. It is designed to be impossible to reverse, meaning you can't get the original text back from the hash.
Which hash algorithm should I use?
For general security and integrity, SHA-256 is the recommended standard. MD5 and SHA-1 are considered cryptographically broken and should only be used for basic integrity checks or legacy system compatibility.
Are my files uploaded to your server for hashing?
No. Our tool uses the Web Crypto API to process everything directly in your browser. Whether you hash text or a file, the data stays on your device.
What is a 'collision' in hashing?
A collision occurs when two different inputs produce the same hash output. High-quality algorithms like SHA-256 are designed to make collisions practically impossible.
Can I use this for password storage?
While this tool generates hashes, production password storage should use dedicated algorithms like Argon2 or bcrypt with unique salts. This tool is best for verifying file integrity or generating one-off checksums.
