This function handles the RSA encryption with the public key components provided when initializing the RSA cryptographic core with the XSecure_RsaInitialize function.

Note: The Size passed here needs to match the key size used in the XSecure_RsaInitialize function

Prototype

int XSecure_RsaPublicEncrypt(XSecure_Rsa *InstancePtr, u8 *Input, u32 Size, u8 *Result);

Parameters

The following table lists the XSecure_RsaPublicEncrypt function arguments.

Table 1. XSecure_RsaPublicEncrypt Arguments
Name Description
