Description:
In this 12-video course, you will explore Public Key Infrastructure and its components, the basics of certificates and certificate authorities, using a Certificate Revocation List (CRL), and how secure web sites work with secure sockets layer (SSL). You will begin with an overview of Public Key Infrastructure and its components, and then take a look at certificates and the different types. This leads into a demonstration of configuring certificate properties. You will discover how to identify certificate authority types and hierarchies, and then watch how to install a certificate authority. Next, you will observe how digital signatures work, and explore how SSL is used to secure web traffic. Another demonstration on SSL shows how to enable a website. Next, you will learn the purpose of a CRL and how it works, and then watch a demonstration of CRLs in use—revoking a certificate and describing the effects of revocation. The final exercise involves installing a certificate authority and securing web traffic to an Internet Information Services (IIS) webserver by installing a certificate.

Description:
Learners will discover two core cryptography services, encryption and hashing, in this 14-video course. Examine the goals of information security, symmetric and asymmetric encryption, and using the Caesar cipher. Begin by taking a look at the goals of information security. Then explore cryptography services and how to associate those services with goals of information security, and receive an overview of encryption and encryption history. Next, watch a demonstration of how to use the CrypTool and the Caesar cipher. Following this, you will examine symmetric encryption, and define common symmetric encryption algorithms. Another demonstration covers CrypTool and symmetric encryption. Learners will be introduced to asymmetric encryption; learn how to define common asymmetric encryption algorithms; and explore the purpose of hashing, and define common hashing algorithms. The final tutorial demonstrates use of the CrypTool and hashing. The concluding exercise involves downloading and installing CrypTool v1, creating a text file, creating an MD5 and SHA1 hash of the file, changing the file and checking the hash value again, and encrypting text with Caesar cipher.
