Frequently Asked Questions
What is a hash?
A cryptographic hash function converts any input data into a fixed-length output (hash/digest). The same input always produces the same output, but it's computationally infeasible to reverse the process or find two inputs with the same hash.
Which algorithm should I use?
SHA-256 is the most commonly recommended algorithm for security-sensitive applications. SHA-512 provides higher security at the cost of longer output. SHA-1 is deprecated for security use but still used for checksums.
Is this secure?
This tool uses the browser's native Web Crypto API (SubtleCrypto), which is the same implementation used by TLS and other security-critical systems. No data leaves your device.
