Osasu

What is Osasu?

Osasu is encryption software for typed text and files on your computer. Compared to other encryption software, Osasu is incredibly easy (and fast) to use. Osasu puts you in control of encrypting files and written text – you are able to visually confirm that your data is encrypted. Unique features, like shortcut keys, allow you to encrypt text in a split-second. You can also encrypt multiple files a time, including Microsoft Office documents, photos, videos, music – anything. Osasu uses a combination of RSA public-key encryption and an AES 256-bit cipher, which is approved for U.S. top-secret military use.
  Very easy to use encryption software for Windows
  Secure your conversations over Skype, Facebook, email, etc.
  Encrypt and decrypt text instantly using keyboard shortcuts
  Encrypt and decrypt multiple files easily
  Supplement your existing data loss prevention (DLP) software
  Verify files and generate hashes via SHA-1, MD5, Whirlpool, etc.
  Uses military-grade AES-256 encryption and open source technology
  Does not require an Internet connection or any sort of website login
  Instruction manual and videos will have you up and running in minutes

Example Uses

Need to send sensitive information through Skype or email?
The government may be watching – quickly encrypt what you've typed using Osasu's keyboard shortcuts.
Uploading to the cloud?
Evidence suggests the big cloud data companies have installed backdoors for government spying. Encrypt each file before it leaves your computer.
Want to keep your files private?
Make them unreadable with Osasu's encryption. Osasu will neither confirm nor deny whether your master password is correct.
Sending incriminating photos or documents?
Maintain confidentiality by selecting all of your photos and documents at once and encrypt in seconds.
Storing medical information in a spreadsheet?
Use Osasu's keyboard shortcuts to encrypt the patient's personal information instantly. Secure data entry without the problems of separate tools.
Want to check if downloaded files have been altered or corrupted?
Compare published SHA-1 hashes with those computed in Osasu via batch processing. If even one byte is different, you will know it!

How It Works

Here's an example of how Osasu works for email encryption:

1. You (Bob) and a friend (Alice) both have a copy of Osasu and have already established Contacts for one another. In your Osasu, Alice is the selected Contact.
2. You type Alice an email in your email client (Gmail, Yahoo, Outlook, Thunderbird, etc.). You highlight your typed email text using your mouse (or keyboard) and use the encryption keyboard shortcut (default: Ctrl+C+E) or use the Encrypt button (if using Osasu's Composer).
3. The encrypted text can now be pasted back over the original text. Press Ctrl+V (or depending on your email client, Edit > Paste) to paste the encrypted text. With only the encrypted text present, you are safe to send the encrypted email to Alice.
4. When Alice receives the email, she makes sure to select you as the Contact, then she highlights the encrypted text and decrypts it using the decryption keyboard shortcut (default: Ctrl+C+D).
5. Alice can now read the original text once she pastes it via Ctrl+V (or Edit > Paste, if available) anywhere she likes (e.g. Osasu's Composer).

Tips:

• You can enable Osasu's Keyboard Log to keep track of all encrypted and decrypted text handled by the keyboard shortcuts during back-and-forth conversations (e.g. Skype).

• For encrypting and decrypting files, the process is similar to the one described above.

• To encrypt files just for personal use, you would create two Contacts for yourself. You would encrypt from one of these Contacts and decrypt from the other.

• For corporate environments, you can create a Contact that represents multiple people or a department, for example. You would then safely share the public and special key for this Contact among those who should have access.

• Note that special care should be taken when exchanging the public and special keys during the New Contact process.

• Osasu is zero-knowledge software. Your master password is not saved anywhere. If you forget your master password, you will not be able to access your contacts.
