Frequently Asked Questions
A hash function takes input data and produces a fixed-size string of characters (the hash). It's a one-way function — you can't reverse a hash back to the original data.
SHA-256 is recommended for most purposes. SHA-1 is considered weak for security. SHA-384 and SHA-512 provide longer digests for higher security needs.
Yes, all hashing is performed in your browser using the Web Crypto API. Your data never leaves your device.
