What Encrypt / Decrypt Text does

local-first

Encrypt / Decrypt Text protects pasted text locally with AES-GCM and a passphrase-derived key. The encrypted output is a portable JSON package containing algorithm, salt, IV, iterations, and ciphertext, so it can be saved, shared, and decrypted later with the same passphrase without sending data to a server.
