Is the hash computed locally?

Yes. The Web Crypto API runs entirely in your browser. Your text is never sent to a server.

SHA-256 is a cryptographic hash function that produces a 256-bit (32-byte) hash value, commonly used for data integrity verification.

Can I reverse a SHA-256 hash?

No. SHA-256 is a one-way function. You cannot recover the original text from a hash.

Yes. The same input always produces the same SHA-256 hash.
