Can a cryptographic hash like SHA-256 be reversed back into plaintext?

No. Cryptographic hashes are one-way mathematical functions designed to be irreversible. They are used for integrity verification, digital signatures, and tamper detection.

Is my confidential plaintext or password transmitted over the network?

Never! All hashing executes 100% inside your local device’s CPU using browser WebCrypto. Your plaintext never travels over any network connection.
