Evaluating Cryptographic Algorithms in Your Organization’s PKI System 

In an era of growing cybersecurity threats, organizations are taking a closer look at their Public Key Infrastructure (PKI) systems. With the right algorithms in place, PKI systems can help protect sensitive data, authenticate users, and ensure secure communication across networks. How do you evaluate cryptographic algorithms for your organization’s needs? This blog post will guide you in evaluating cryptographic algorithms in your organization’s PKI system by trying to simplify security with managed PKI

What are Cryptographic Algorithms? 

Cryptographic algorithms are mathematical functions used to secure digital data. These algorithms are used in PKI systems to ensure authorized parties can access sensitive information. Symmetric cryptography uses the same key to encrypt and decrypt data, while asymmetric cryptography uses a public key and a private key. 

Why is it important to evaluate Cryptographic Algorithms in a PKI System? 

Cryptographic algorithms are crucial to the security of a PKI system. Therefore, it is essential to evaluate the strength of these algorithms to ensure that they can withstand attacks from hackers. Additionally, cryptographic algorithms have a finite lifespan, and it is important to evaluate them periodically to determine if they may be vulnerable to new attack methods. 

How to Evaluate Cryptographic Algorithms: 

Several factors must be considered when evaluating cryptographic algorithms, including the strength of the algorithm, its availability, and the level of acceptance in the industry. The National Institute of Standards and Technology (NIST) has outlined guidelines for evaluating cryptographic algorithms, including the need to conduct testing in various environments and using various tools. Assessing cryptographic algorithms in real-world scenarios is important since attackers often take advantage of vulnerabilities in these environments. 

Determine Your Security Requirements 

Once you understand your PKI system architecture, it’s time to determine your security requirements. This will help you narrow down your choices of cryptographic algorithms. If you are dealing with sensitive data, you may require a stronger encryption algorithm that can withstand attacks from quantum computers. 

Understand Your PKI System Architecture 

It’s important to understand your system architecture before you can evaluate the right cryptographic algorithms for your PKI system. This will help you identify which algorithms best fit security requirements and performance needs. Specifically, you should consider the size of your organization, the number of users, and the types of applications running on the system. 

Consider Performance Needs 

In addition to security requirements, you should consider performance when evaluating cryptographic algorithms for your PKI system. This includes factors such as processing speed, memory usage, and the need for hardware acceleration. Remember that stronger cryptographic algorithms often require more processing power, so balancing security and performance needs is important. 

Evaluate the Strength of Cryptographic Algorithms 

There are many cryptographic algorithms to choose from, each with strengths and weaknesses. Some of the most popular encryption algorithms include AES, RSA, and ECC. When evaluating these algorithms, it’s important to consider factors such as key length, resistance to attacks, and availability of open-source implementations. You can also consult industry standards such as NIST to determine which algorithms have been officially recommended. 

Continuously Monitor and Update Your PKI System 

Finally, it’s important to continuously monitor and update your PKI system to ensure it is always protected from the latest cybersecurity threats. This includes regularly reviewing and updating your cryptographic algorithms as new vulnerabilities are discovered. Additionally, you should keep your system up-to-date with the latest patches and upgrades to ensure it runs at peak performance. 


Evaluating cryptographic algorithms in your organization’s PKI system can be complex. Still, with the proper knowledge and guidance, it is possible to make an informed decision that will help protect your data and secure your networks. By understanding your system architecture, determining your security and performance needs, evaluating the strength of cryptographic algorithms, and continuously monitoring and updating your system, you can create a robust and reliable PKI system that will stand up to any cybersecurity threat.
