Frequently Asked Questions

What is a hash function?

A hash function is a mathematical algorithm that converts data of any size into a fixed-size output (hash value). The same input will always produce the same output, but even a small change in the input will produce a completely different hash value.

What are hash functions used for?

Hash functions are used for data integrity verification, password storage, digital signatures, file identification, and as building blocks in many cryptographic protocols. They provide a way to quickly verify that data hasn't been altered.

Which hash algorithm should I use?

For general data integrity checking, SHA-256 is recommended as it provides a good balance of security and performance. For password storage, Bcrypt or Argon2 are recommended as they are designed to be slow and resistant to brute-force attacks.

Is my data secure when using these tools?

Yes, all hashing calculations are performed entirely in your browser. Your data never leaves your device or gets sent to any server. For sensitive data, you can even use these tools offline once the page is loaded.
