What is cryptanalysis?

Cryptanalysis refers to the process of analyzing and breaking encrypted data without having access to the encryption key. It involves studying the algorithms, protocols, and techniques used in encryption to identify weaknesses or vulnerabilities that could be exploited to retrieve the original message even when the encryption is intended to protect it.

This practice is crucial in the field of cybersecurity, as successful cryptanalysis can reveal the integrity of systems that rely on encryption for security. By understanding cryptanalysis, security professionals can better assess the robustness of encryption methods and improve defenses against potential attacks.

In contrast, encrypting data securely pertains to the methods used to create encryption rather than the act of breaking it; generating cryptographic keys involves establishing secure keys for encryption rather than attacking the encryption; and recording data transmissions focuses on monitoring without direct involvement in analyzing the encryption itself.
