NoteArmor Secure Notepad Pro
Write. Encrypt. Protect.
NoteArmor Secure Notepad Pro is built for developers, security researchers, journalists, and anyone who refuses to trust plaintext. Every note is encrypted with AES-256 before it touches disk. A triple-layer authentication system (password + keyfile + TOTP) ensures only you can open your vault. The offline RSA-4096 licensing engine means your license never phones home — no cloud dependency, no privacy risk.
