Cryptographic issues
- [Presenter] Understanding cryptographic principles and common issues like weak algorithms, improper key management, and insecure data storage is essential for assessing and improving the security of cryptographic implementations. Cryptographic involves using mathematical computations algorithm to secure data by transforming it into a format that is unreadable without a correct key. For example, encryption transforms plain text into cipher text using an algorithm and a key. Decryption reverses this process by turning cipher text into plain text using the same key or related key. Cryptography principles include confidentiality, integrity, authentication, and non-repudiation. Weak algorithms are common cryptographic issues. These are outdated or insecure algorithms that can be easily broken by attackers. Hashing algorithms like MD5 and SHA1 are considered weak due to vulnerabilities that allow for collision attacks. As a security researcher, check for the use of weak algorithms and…
