u32 XilSKey_CrcCalculation

(

const u8 *

Key

)

This function Calculates CRC value based on hexadecimal string passed.

Parameters

Key	Pointer to the string contains AES key in hexadecimal of length less than or equal to 64.

Returns

• On Success returns the Crc of AES key value.
• On failure returns the error code when string length is greater than 64

Note

If the length of the string provided is less than 64, this function appends the string with zeros. For calculation of AES key's CRC one can use u32 XilSKey_CrcCalculation(u8 *Key) API or reverse polynomial 0x82F63B78.

u32 XilSkey_CrcCalculation_AesKey

(

const u8 *

Key

)

Calculates CRC value of the provided key.

Key should be provided in hexa buffer.

Parameters

Key	Pointer to an array of 32 bytes, which holds an AES key.

Returns

Crc of provided AES key value. To calculate CRC on the AES key in string format please use XilSKey_CrcCalculation.
