Crypto Lab -- Secret Key Encryption / SEEDUbuntu

The secret-key encryption lab involves analyzing a monoalphabetic substitution cipher through frequency analysis to recover the original English text. Furthermore, participants encrypt a picture using Electronic Code Book (ECB) and Cipher Block Chaining (CBC) modes. The encrypted pictures are then manipulated to reveal potential vulnerabilities in the encryption process.

Secret-Key Encryption Lab provided a comprehensive exploration of secret-key encryption concepts, attacks, and common mistakes. The lab exposed common mistakes made by developers, emphasizing the importance of robust encryption practices.
Task 1 in the Secret-Key Encryption Lab involved frequency analysis on a monoalphabetic substitution cipher.
Task 3 explored the differences between Electronic Code Book (ECB) and Cipher Block Chaining (CBC) encryption modes. By encrypting a simple picture file and analyzing the results, We gained insights into the importance of choosing the right encryption mode. The exercise also underscored the potential risks associated with using ECB, as observable patterns were present in the encrypted image.
