Encryption – and its opposite, decryption – is the process of converting data into code that is unreadable by a human who does not possess the necessary key for decrypting it, or turning it back to a readable form. Encryption is one of the best methods that can be used for protecting sensitive data from loss or inappropriate access, but for many it is still often an afterthought, used in a largely ad hoc manner. Encryption is hot now because of its potential to greatly reduce the fallout from data breaches and to achieve compliance with ever more stringent data protection regulations. No organisation can afford to leave sensitive information in the clear for easy pickings.
