encryption

   The process of encoding information in an attempt to make it secure from unauthorized access, particularly during transmission. There verse of this process is known as decryption.
   Two main encryption schemes are in common use:
   • Private (Symmetrical) Key
   An encryption algorithm based on a private encryption key known to both the sender and the recipient of the information. The encrypted message is unreadable and can be transmitted over nonsecure systems.
   • Public (Asymmetrical) Key
   An encryption scheme based on using the two halves of a long bit sequence as encryption keys.
   Either half of the bit sequence can be used to encrypt the data, but the other half is required to decrypt the data.
