    Cryptography: What It Is and How It Works in Cyber Security

    Cryptography is the practice of securing information by converting it into an unreadable format that only authorized parties can access. In the field of cyber security, cryptography is used extensively to ensure the confidentiality, integrity, and authenticity of sensitive data. Encryption is the process of converting plain text into ciphertext to ensure that the information it contains is kept secure. Decryption is the process of converting ciphertext back into plaintext when authorized parties need access to the information.

    One of the most common encryption algorithms used in cyber security is the Advanced Encryption Standard (AES). AES is a symmetric key algorithm, which means that the same key is used for both encryption and decryption. This algorithm is widely used in secure communication protocols, including Secure Sockets Layer (SSL) and Transport Layer Security (TLS).

    Another important aspect of cryptography in cyber security is the use of digital signatures. Digital signatures ensure that messages can be verified as being from an authentic sender and have not been tampered with during transmission. They are used extensively in e-commerce, online banking, and other applications where message authentication is critical.

    Key takeaways:

    • Cryptography is the practice of securing information by converting it into an unreadable format that only authorized parties can access
