Frequently Asked Questions
Q: What is a cryptographic hash?
A cryptographic hash function is an algorithm that takes an input string and returns a fixed-size string of bytes (checksum). The output is deterministic: the same input will always produce the same hash, but even a minor change to the input changes the hash entirely.
Q: Is Web Crypto API secure?
Yes. Web Crypto is a native browser specification implemented in low-level compiled browser code, making it extremely fast, secure, and isolated from external injection scripts.
