AES_CCMEncrypt
Encrypts a data buffer in the CCM mode.
Syntax
IppStatus ippsAES_CCMEncrypt(const Ipp8u* pSrc, Ipp8u* pDst, int len, IppsAES_CCMState* pState);
Include Files
ippcp.h
Parameters
pSrc |
Pointer to the input plaintext data stream of a variable length. |
pDst |
Pointer to the resulting ciphertext data stream. |
len |
Length of the plaintext and ciphertext data stream in bytes. |
pState |
Pointer to the IppsAES_CCMState context. |
Description
The function encrypts the input data stream of a variable length in the CCM mode as specified in NIST SP 800-38C.
Return Values
ippStsNoErr |
Indicates no error. Any other value indicates an error or warning. |
ippStsNullPtrErr |
Indicates an error condition if any of the specified pointers is NULL. |
ippStsContextMatchErr |
Indicates an error condition if the context parameter does not match the operation. |
ippStsLengthErr |
Indicates an error condition if len is less than zero or the value that accumulates len parameters from previous calls to AES_CCMEncrypt with the current value of len exceeds the tag length specified in the previous call to AES_CCMMessageLen. |
