Frequently Asked Questions
What is a hash?
A hash is a fixed-size string generated from input data using a mathematical function. The same input always produces the same hash, but you cannot reverse a hash to get the original input.
Which algorithm should I use?
SHA-256 is recommended for most uses. MD5 and SHA-1 are considered weak for security but still useful for checksums.
Is my data safe?
Yes. All hashing is done in your browser using the Web Crypto API. No data is sent to any server.
