Encryption is the process of transforming information (referred to as plaintext) using an algorithm (called cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key; the reverse is called decryption.

In case of Public Key Cryptography where a key pair is generated for encryption, the clear text is encrypted using one key and complementary key is used for decryption.

1.2. Necessity to backup :
Following are some situations when it is necessary to recover encryption keys :
** An employee loses the private encryption key and cannot read encrypted mail/documents (tender etc.).
** An employee is on an extended leave, and someone needs to access an encrypted document.

** An employee leaves the company, and company officials need to perform an audit that requires gaining access to the employee’s encrypted data. Therefore, if data is being encrypted, somebody must manage the keys and there must be a key backup/recovery procedure in place.
