Securing data and resources, whether they are in transit or rest is a major concern to IT Managers or to the organization. Due to the world we live in, which is full of security risks originating both in house and from outside. One way to protect is to use cryptography to encrypt data in transit and at rest. RSA algorithm is a popular one, when used using SSL sessions with digital signatures provides data integrity, non-repudiation and authentication.

Encryption keys are private and must be associated with person or organization. Digital certificates bind the identity of the certificate holder to an encryption key. Digital certificates play an import role in securing business data and processes.
