Secure Sockets Layer (SSL) is a cryptography protocol to protect web communication. Understanding Secure Sockets Layer takes the complicated subject of using TLS/SSL with public key infrastructure (PKI) for trusted encryption and identity verification, and breaks it down into easy-to-understand components that entry-level IT technicians, consultants, and support staff need to know—regardless of the types of computers, users, or networks supported. Join author Sean Colins for a focused and approachable course that will extend your knowledge of common SSL concepts and practices, including:

SSL communications
Certificate authorities
Public key infrastructures
Symmetric and asymmetric key pairs
Cryptographic hash functions
Encryption algorithms


Start now, and by the end of this course you'll have the knowledge to create SSL certificates, as well as revoke and renew them, from the command line
