Data Encryption


Data encryption is a means of scrambling the data so that is can only be read by the person(s) holding the 'key' - a password of some sort. Without the 'key', the cipher cannot be broken and the data remains secure. Using the key, the cipher is decrypted and the data is returned to its original value or state.

Each time one wishes to encrypt data, a key from the 72,000,000,000,000,000 possible key variations, is randomly generated, and used to encrypt the data. The same key must be made known to the receiver if they are to decrypt the data.
