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.
