Cryptographic algorithms protect critical properties of modern software. With the potential danger posed by the advent of quantum computers, it has become more important for companies to identify which algorithms are present in the systems they use or ship to customers.While mature algorithm usage detection solutions for languages which target the JVM are readily found when working at the source code level (e.g. CodeQL, Semgrep), solutions working at the bytecode level are less prevalent, outdated, or do not provide comprehensive coverage.
