This function handles the RSA decryption for data available at 64-bit address with the private 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_RsaPrivateDecrypt_64Bit(XSecure_Rsa *InstancePtr, u64 Input, u32 Size, u64 Result);Parameters
The following table lists the XSecure_RsaPrivateDecrypt_64Bit function arguments.
| Name | Description |
|---|---|
| InstancePtr |
- Pointer to the
XSecure_Rsa
instance
|
| Input | - Address of the buffer which contains the input data to be decrypted |
| Size |
- Key size in bytes, Input size also should be same as Key size mentioned. Inputs supported are
|
| Result | - Address of buffer where resultant decrypted data to be stored |
Returns
- XST_SUCCESS - If decryption was successful
- XSECURE_RSA_DATA_VALUE_ERROR - If input data is greater than modulus
- XSECURE_RSA_STATE_MISMATCH_ERROR - If State mismatch is occurred
- XST_FAILURE - On RSA operation failure
