This function initializes a a XSecure_Rsa structure with the default values located at a 64-bit address required for operating the RSA cryptographic engine.
Note: Modulus, ModExt and ModExpo are part of partition signature when authenticated boot image is generated by bootgen, else the all of them should be extracted from the key
Prototype
int XSecure_RsaInitialize_64Bit(XSecure_Rsa *InstancePtr, u64 Mod, u64 ModExt, u64 ModExpo);
Parameters
The following table lists the XSecure_RsaInitialize_64Bit
function arguments.
Name | Description |
---|---|
InstancePtr | - Pointer to the XSecure_Rsa instance |
Mod | - Address of the key Modulus of key size |
ModExt |
- Address of the pre-calculated exponential (R^2 Mod N) value
|
ModExpo | - Address of the buffer which contains key exponent |
Returns
- XST_SUCCESS - If initialization was successful
- XSECURE_RSA_INVALID_PARAM - On invalid arguments
