The focal point of this study is the assessment of the algorithmic part of the random number generators supporting cryptographic functionalities in the web browsers Chromium (Version 122.0.6168.2), Firefox (Version 120.0) and Safari (assuming usage of Corecrypto 2022). The entire implementation of the random number generators is explained in detail to allow a full understanding of the flow of information, starting at the point where the entropy is gathered up to the point where random numbers are returned. Each of the entropy sources providing entropy to the random number generators is described to the extent that the used interface is clarified.
