Discovering cryptographic failures

Cryptographic failures on a web application simply define the security vulnerabilities found within a web application that allow a threat actor to gain access to confidential data, such as users' credentials, that are either stored on a server or transmitted over a network. When deploying web applications, it's always important to ensure best practices on using recommended cryptographic solutions, such as secure encryption algorithms, to ensure data in motion, data at rest, and data in use are always kept safe from unauthorized users such as threat actors.

If a developer implements a web application using a weak or insecure encryption algorithm, threat actors can simply discover the type of encryption algorithm and discover security vulnerabilities. Once a vulnerability is found, it's only a matter of time for the vulnerability to be exploited by a threat actor. As a penetration tester, understanding how to test for cryptographic...
