Certificates can be delivered and transferred between systems in a variety of different formats. In this video, you’ll learn about some of the most common certificate file formats. << Previous Video: Types of Certificates Next: Security+ SY0-501 Course Index >> In our previous videos, we saw that an X.509 certificate has a very standard format. […]

The details of a public key infrastructure are sometimes the most important pieces. In this video, you’ll learn about online and offline CAs, OCSP stapling, certificate pinning, and more. << Previous Video: PKI Components Next: Types of Certificates >> Our public key infrastructures rely on trust. Usually this trust is provided by a certificate authority.

Creating a public key infrastructure requires extensive planning. In this video, you’ll learn about the most important components required to build a successful PKI. << Previous Video: Wireless Security Next: PKI Concepts >> “PKI” stands for Public Key Infrastructure. And it’s a way to describe the policies, the procedure, the hardware, the software, and the

There are many different methods of providing wireless security. In this video, you’ll learn about wireless security modes, captive ports, and WPS. << Previous Video: Wireless Authentication Protocols Next: PKI Components >> If you’re configuring a wireless access point at your home or at your office, you may have a number of different options available

Gaining access to a wireless network may take a number of different paths. In this video, you’ll learn about the authentication protocols used to provide authentication to wireless networks. << Previous Video: Wireless Cryptographic Protocols Next: Wireless Security >> We know that encrypting our data on a wireless network is important. But we also need

We rely on strong encryption protocols to keep our wireless communications secure. In this video, you’ll learn about the security features associated with WPA and WPA2. << Previous Video: Obfuscation Next: Wireless Authentication Protocols >> Unlike a wired network connection, wireless networks can be heard by anyone who’s close by who would care to listen

One way to slow down an attacker is to make things unclear. In this video, you’ll learn about some common implementations of obfuscation. << Previous Video: Key Stretching Algorithms Next: Wireless Cryptographic Protocols >> What if you didn’t want to encrypt information but you still wanted to make it a little bit more difficult to

One way to extend the capabilities of a relatively small key size is to implement key stretching. In this video, you’ll learn about the libraries that application developers can use to stretch their keys. << Previous Video: Hashing Algorithms Next: Obfuscation >> When we’re implementing encryption in our applications, we may find that the encryption

There are many methods and implementations of cryptographic hashing. In this video, you’ll learn about some of the most popular hashing algorithms. << Previous Video: Asymmetric Algorithms Next: Key Stretching Algorithms >> One type of hash that’s been around for a while but you’ll still see it in use today is MD5, or the MD5

Asymmetric encryption has enabled the exchange of symmetric keys, encryption of data, digital signatures, and other significant security features. In this video, you’ll learn about these asymmetric algorithms and their use. << Previous Video: Block Cipher Modes Next: Hashing Algorithms >> One popular form of asymmetric cryptography is the Diffie-Hellman key exchange. This key exchange
