RSA introduction

The article introduces the RSA theory, how to get the RSA parameter, how to encrypt/decrypt with the RSA algorithms.

RSA is an asymmetric cryptographic algorithm and widely used in encryption/decryption application and signature application. It completes encryption and decryption operations by encrypting the message with the public key and decrypting with the private key. In order to support security requirements, it is also used in many places in the LPC55 series, such as:

- RSA digitally signs the application code with the private key, and verifies the authenticity of the code through RSA signature verification in secure boot. This is implemented in LPC55 secure boot.

For the LPC family, the mbedtls library is used to implement the RSA algorithms with software.
