Cryptography

Cryptography is the practice of secure communication in the presence of third parties. It involves the use of mathematical algorithms and protocols to convert plain text (unencrypted data) into cipher text (encrypted data) to ensure secure communication and data protection.

Cryptography is used to protect sensitive information such as personal information, financial information, and business secrets. It is commonly used to secure data transmitted over the internet, including online banking transactions, email communication, and website logins.

There are two main types of cryptography: symmetric key cryptography and public key cryptography. In symmetric key cryptography, the same key is used to both encrypt and decrypt the data. In contrast, public key cryptography uses two different keys, one for encryption and one for decryption.

Cryptography is a crucial aspect of cybersecurity and is used in a variety of applications, including secure messaging apps, virtual private networks (VPNs), and encrypted storage devices. As a product manager, it's important to understand the basics of cryptography to ensure that the products you're working on are secure and protected from unauthorized access.

That said, typically your engineering counterparts or your information security counterparts will be the ones who will stay up-to-date with the latest advancements in cryptography to ensure that your products are utilizing the most secure and effective encryption methods available.
