Cryptographic Key Usage
Identifying the cryptographic keys an application really uses, what they are used for, and how they are stored, is a critical step towards many transformation projects. For example: automating cryptography inventory, or preparing to migrate an application to the cloud. This information also allows us to check that all the right data is being protected, and find a cloud crypto service that can accommodate the keys the application needs.
Previously, this was a time-intensive manual job, which involved inspecting code or testing the application environment. Now, Cryptosense Analyzer can automate key usage detection.
How Analyzer Finds Key Usage Information
Unlike other tools on the market, Cryptosense Analyzer is able to see inside running applications, this gives it a unique insight into the real workings of the application.
Cryptosense Analyzer works by tracing all the calls an application makes to its crypto libraries in a IAST style. Once this information has been passed through our analysis engine, you get an output showing cryptography inventory information and vulnerability analysis on all the cryptographic operations the application carries out. Since February 2020, Analyzer also infers a list of cryptographic keys, and keeps track of what they are used for.
What the Key Lifecycle Report Looks Like
Here you can see the result we got when we ran Analyzer on the Jenkins application. The interface allows you to filter out certain keys, such as those that are unused (often public key certificates in TLS keystores), and ephemeral keys (like TLS session keys).
If you are planning a migration to cloud cryptography, you can also check which keys would be suitable for direct use as a bring-your-own key in cloud crypto services.
For each key, you can click to drill down on all the operations carried out by that key.
And for each operation, you can see the exact lines of code that made the calls.
What’s next? More help with Cloud Migrations.
We have been testing the new Key Lifecycle detection feature with a group of early users. They have already found that having accurate information showing what keys are doing and how they are stored is a great help for speeding up migration work. It has also helped them to easily identify poorly protected keys and missing encryption.
We are working on making it even easier to transform key storage for the cloud. Sign up for our newsletter (box in the upper right) to keep up to date with new features as they’re released, or get in touch for a demo.
