Hashing uses the browser's built-in SubtleCrypto API, which implements SHA-256 natively. The hash updates as you type.
The text you enter is never sent to a server. All hashing happens inside your browser tab.
SHA-256 is a cryptographic hash function that produces a fixed 256-bit (64 hex characters) output. It is widely used for data integrity verification, digital signatures, and password hashing.
No. SHA-256 is a one-way function — you cannot recover the original input from the hash. If you need reversible encoding, use Base64 instead.
No. Hashing uses the browser's built-in SubtleCrypto API and runs entirely on your machine.
