Frequently Asked Questions

How is the hashing computed?

SHA-256 and SHA-512 are calculated using the browser's hardware-accelerated Web Crypto API (SubtleCrypto interface). The MD5 hash is computed using a lightweight client-side algorithm. All encodings and decodings are completed inside your browser. No data ever leaves your device.

What is the difference between Hashing and Encoding?

Hashing (like MD5, SHA-256) is a one-way mathematical function. It turns an input into a fixed-length signature that cannot be reversed. Encoding (like Base64) is a two-way conversion designed to safely transmit binary data over text protocols, and it can be easily decoded back to the original string.
