Want to say, also known as 想曰 in Chinese, is a text encryption tool that lets users freely express and share their thoughts through encrypted messages. It uses modern encryption technology with a multi-algorithm cascade scheme combining AES256-CTR and ChaCha20-Poly1305-IETF for high security. The tool supports ciphertext formats in Chinese, Base64, Emoji, zero-width characters, Japanese, Korean, and pictographic symbols. Zero-width ciphertext can be embedded invisibly within URLs, Chinese text, English text, or other visible characters. Key exchange uses ECDH-X25519 and ECDH-P521, while key derivation employs Argon2id with HKDF-SHA512 to resist brute force attacks. All encryption and decryption operations are performed locally, ensuring user data never leaves the device. Key features include multiple disguise modes for sharing encrypted content without attracting attention, offline client availability, and a built-in mismatch page that displays a fake interface during password entry to prevent shoulder-surfin
