Primekey Case Study

Leading open-source PKI software provider Primekey uses Cryptosense Analyzer to efficiently identify potential crypto and key-management vulnerabilities.

Headquartered in Stockholm, Sweden, PrimeKey Solutions develops and supports the most downloaded open source enterprise public-key infrastructure (PKI) software available, providing businesses and organisations around the world with the ability to implement security solutions such as e-ID, e-Passports, authentication, digital signatures, unified digital identities and validation.

Easy Integration

PKI is at the core of enterprise security, and relies on cryptography to securely manage keys, certificates and authorization. The core PrimeKey PKI offering, EJBCA, is an enterprise Java application consisting of hundreds of thousands of lines of code and linking with a number of libraries. Using Cryptosense Analyzer, the PrimeKey development team were able to test security of crypto use, key-management, randomness quality, and password storage across the application. “Cryptosense tools leverage our existing test cases, so integration was straightforward”, commented Gustavsson, “that means we can continue to use the tool to test new developments and catch problems early in the development cycle.”

Cryptosense tools work by tracing calls made by the application to cryptographic libraries during execution. The trace is recorded as an abstract logical model, which is then analyzed by Cryptosense software to detect both shallow crypto bugs like insecure algorithms and short keys as well as deeper cryptographic flaws that rely on interactions between operations over the course of an execution. The analysis algorithms are based on years of academic research by the Cryptosense founders as well as input from standards organisations, public results and in-house research.

Reassuring Users

Using the tool also helps raise awareness of crypto security issues among developers and helps to build a culture of best practice. “After investigating the issues found, we can also use the reports to explain to our clients and prospects how we manage cryptographic security”, explains Gustavsson. “All our customers are security-sensitive, which makes this assurance important.”

We already use a variety of tools to ensure software quality, but we see security as an area of continuous improvement, and Cryptosense tools give us a cryptography-focused view that other tools can’t provide. A strong statement in itself, given the fact that PrimeKey’s teams of engineers work day in and day out with cryptography.
