Main Features

Safe private notes

As with Notepad, you can easily open or create, edit, and save any text information that is safely stored. Very precise implementation with strongest crypto-algorithms used in cascade. You need only remember one single master password for absolute security for all you data.

Safe messages

Safe Notes Mail is a feature that provides cryptographic privacy and authentication for data communication. It can be used for encrypting, decrypting, and signing messages, e-mails, or texts. It is by far the safest public-key cryptography, or asymmetric cryptography in the world.

Password Generator

And checker. Very precise with nice graphics design. Charts contains the entire history of computer performance. It can display the real strength of entered passwords for many popular encryption tools. It also includes high grade approximation of the future progress of decryption for the next millennium.

Steganography, hiding information inside the picture so thats it is impossible to detect this. It meets the strongest military standards. Can by use high grade image size resampler with Bicubic, Lanczos, Catmull-Rom, Mitchell, Gausian and other resample filters.
Secure mailing with simple copy & paste technique. Safe transfer of private documents, texts, photos via internet.
Create ultra secure Bitcoin wallet addresses, using a precise safe random generator and three-step independent verification.
Extreme password engine, high security even with a short password.
Supports all versions of Windows, Linux system with Wine.
SafeNotes is a quantum-safe cryptography.

Wipe Tool, this is a sensitive data destruction tool, for secure delete files or free space wipe from hard drive or memory keys. You can choose from five different algorithms, such as U.S. DoD 5220.22-M(E) or Gutmann method.
The strongest crypto algorithms are used simultaneously with safe-cascade. When AES encryption is broken, for SafeNotes this is not a problem. Plugin support for any external encryption.
Very easy to use and very easy installation. The intelligence and power is hidden inside the application with hundreds of thousands source code lines.
Highly portable; you can use only one exe application without installation. None information is writed out of data directory.
Currently available in over 30 languages and with support for any additional language mutations.
Fully documented encryption module. Source code in the distribution.
