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 theIppsAES_CCMStatecontext.
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 isNULL.
- ippStsContextMatchErr
- Indicates an error condition if the context parameter does not match the operation.
- ippStsLengthErr
- Indicates an error condition iflenis less than zero or the value that accumulateslenparameters from previous calls toAES_CCMEncryptwith the current value oflenexceeds the tag length specified in the previous call to AES_CCMMessageLen.
