USA Shield is the suite of encryption tools for personal and professional security. It allows you to protect the privacy of your sensitive files and messages by encrypting them with up to three strong cryptographic algorithms. Once the information has been encrypted, it can be stored on insecure media or transmitted on an insecure network - like the Internet- and still remain secret. Later, the information can be decrypted into its original form. USA Shield integrates the strongest cryptography available today into the Windows environment.
