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.
| Name | Description |
|---|---|
| InstancePtr |
Pointer to the
XSecure_Rsa
instance
|
| Input | Pointer to the buffer which contains the input data to be encrypted |
| Size |
Key size in bytes, Input size also should be same as Key size mentioned. Inputs supported are
|
| Result | Pointer to the buffer where resultant decrypted data to be stored |
Returns
- XST_SUCCESS - If encryption was successful
- XSECURE_RSA_INVALID_PARAM - On invalid arguments
- XSECURE_RSA_STATE_MISMATCH_ERROR - If State mismatch is occurred
