As with Notepad, you can easily open or create, edit, and save any text information that is safely stored.

Genuine password checker and creator, very precise with nice graphics design.

Steganography, to hide information within the picture, so it is impossible to detect this.

Ultra secure Bitcoin wallet creator, using a precise safe random generator and three-step independent verification.



Very precise implementation with strongest crypto-algorithms used in cascade.

Independent keys, with six different ciphers uses symmetric encryption with 6720-bits. With the Premium version you can use eight encryption algorithms and up to 16384-bits.

Sensitive information (e.g. passwords) are stored always only in encrypted form with random session key.

Every saved document is fully checked and verified for 100% correct encrypting and saving. All memory operation is wiped after use.



You need only remember one single master password for absolute security for all you data.

True random password generator for your web and app accounts.

Can by used as a very comfortable password manager.

The advanced user mode with an extended range of password characters can significantly increase password security.


  • Safe store of your private notes, texts, info about credit cards, pins, passwords, bitcoin wallets, photos or pictures.
  • Create ultra secure Bitcoin wallet addresses, version 5.0.2 and higher, coming soon.
  • Secure mailing with simple copy & paste technique. Safe transfer of private documents, texts, photos via internet.
  • 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.
  • Genuine Password Checker and Generator, 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 such as TrueCrypt, Keepass, PasswordSafe, 7zip, VeraCrypt, etc. It also includes high grade approximation of the future progress of decryption for the next millennium.
  • 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.
  • Extreme password engine, high security even with a short password.
  • The strongest crypto algorithms are used simultaneously with safe-cascade.
    Note: When AES encryption is broken, more than 99% security software will not be secure. For SafeNotes this is not a problem.
  • Very easy to use and very easy installation. The intelligence and power is hidden inside the application with hundreds of thousands source code lines.
  • SafeNotes is a quantum-safe cryptography.
  • Supports all versions of Windows, Linux system with Wine.
  • Fully documented encryption module. Source code on web.
  • In English with support for other language mutations.

Safe Notes - Cryptography

Why is SafeNotes secure?

Because it uses onlythe best and worldwide accepted hashes and cipher algorithms with precise implementation, and its encoding technique and output file structure is fully documented. Anyone may inspect the created output file from the input data and check it for backdoors or errors.

How secure are the encrypted SafeNotes files?

SafeNotes uses the finest hash algorithm with cycle cascading to generate unique key from passphrase, public master key and salt, and the best encode algorithm in cascade to encode the document. These are the best hash and encode algorithm and, used in these form,are absolutely unbreakable.

The only weak point is your password. Using purely random alphanumerically characters (a-z, A-Z, 0-9) as your passphrase, you need to specify 11 unique characters for 64-bit security. To solve this problem there is built-in passphrase dialog always displaying computed password quality.

What are the details of the encryption used in SafeNotes?

Your password is used as input to create the subkeys and the safekey. Cryptographic functions as SHA1, RipeMD160, Tiger2, SHA256, RipeMD320, SHA512, PBKDF2, BCrypt, SafeCrypt are used for key creation. The number of iterations is 52224.

Ciphers for encryption are AES, Blowfish, Twofish, IDEA, CAST6 and Serpent. They are used one after another in cascade with separate keys and initialization vectors. This requires a key with a 2240-bit length. SafeNotes uses three independent keys, one for head, one for salt and one for data encryption. This will increase the need for keys to 6720-bit. Much more than the most commonly used 128-bit and 256-bit keys.

Typically data is compressed before encryption using zlib, a standard deflate algorithm, described in RFC 1951 and RFC 1950. Two type of Salt is used to prevent rainbow table attacks. First salt, named as Public Master Key, is used after password entering. Second salt is used when file is being saved.

The data in the file header section contains information about the file size, file name and file modification times as well as version information, integrity checksum etc. Header is encrypted with unique key without ties to key for data encryption. For integrity checking two 48bit CRCs are used, binary compatible with CRC32 & CRC16. First is created for original unencrypted data stream and second for all data after encryption including the file header.
