CompTIA Security+ 2008: Cryptography

This course is included in our On-demand training solution.


The central goal of cryptography is to hide information from others. Modern cryptographers use advanced algorithms and computational models to create layers of security and trusts in order to protect information. This course introduces encryption methods using both symmetric and asymmetric encryption techniques, along with trust models, certificates, and algorithms. This course is one of a series in the SkillSoft learning path that covers the objectives for the CompTIA Security+ (2008 Edition) certification exam.

Target Audience

Organizations involved in IT services or training that need to have personnel qualified for onwards delivery of IT support or training; businesses that will need up-to-date Security+ training for their own internal networking support purposes; individuals who are personally interested in establishing credentials for the benefit of their own career prospects.


Although not a prerequisite, it is recommended that CompTIA Security+ candidates have at least two years on-the-job networking experience with an emphasis on security. The CompTIA Network+ certification is also recommended.
