Parameters
- pSrc
- Pointer to the input plaintext data stream of variable length.
- pDst
- Pointer to the resulting ciphertext data stream.
- len
- Length of the plaintext data stream length in bytes.
- pCtx
- Pointer to theIppsAESSpeccontext.
- pIV
- Pointer to the initialization vector for the CBC mode operation.
Description
The function encrypts the input data stream of a variable length according to the CBC mode as specified in [NIST SP 800-38A].
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.
- ippStsLengthErr
- Indicates an error condition if the input data stream length is less than or equal to zero.
- ippStsUnderRunErr
- Indicates an error condition iflenis not divisible by data block size.
- ippStsContextMatchErr
- Indicates an error condition if the context parameter does not match the operation.
