WebJan 3, 2016 · So my guess on what limits the RSA and ECC key size supported by Smart Card RSA and ECC accelerators are: The size of the RAM accessible by the coprocessor, which at least sometime is dedicated and uses a sizable portion of the silicon. That might sometime answer the question. The RAM size accessible by the coprocessor is closely … WebWelcome! This is the repository where you will find all challenges from watevrCTF 2024. All challenges have their sources and build scripts here, so you can explore how they were made. Most of the challenges also have automated solve scripts that you can investigate for a solution, and a few even have writeups.
