Frequently Asked Questions

What is a hash and why is it important?

A hash is a fixed-size string generated from input data using a mathematical function. It's important for data integrity, password security, digital signatures, and ensuring data hasn't been tampered with.

Which hash algorithm should I use?

For modern applications, use SHA-256 or SHA-512. MD5 and SHA-1 are considered weak for security purposes. Choose based on your security requirements and performance needs.

What is salt and why should I use it?

Salt is random data added to input before hashing to prevent rainbow table attacks and make each hash unique. It significantly improves security, especially for password hashing.

How many iterations should I use?

For password hashing, use at least 10,000-100,000 iterations. More iterations make hashes harder to crack but slower to generate. Balance security needs with performance requirements.

Can I reverse a hash to get the original data?

No, hash functions are one-way by design. You cannot reverse a hash to get the original input. This is what makes them secure for password storage and data integrity.

Is my data secure when using this tool?

Yes, all hashing is performed locally in your browser. Your input data is never sent to our servers or stored anywhere. The entire process happens client-side for maximum privacy and security.
