Public Key Cryptography Standards (PKCS) is a set of standards devised and published by RSA Security to promote the widespread use of public-key cryptography. Coursera's PKCS catalogue teaches you about the essential elements of these standards, their utilization in ensuring secure information exchange, and their role in modern internet security practices. You'll learn about the technical aspects of PKCS, including key generation, key exchange, encryption, and decryption. You'll also explore different PKCS standards, such as PKCS#1 for RSA encryption and PKCS#7 for data encryption and digital signatures. This skill is vital for cybersecurity professionals, software engineers, and anyone looking to enhance their understanding of cryptographic protocols and standards.
