Include Files
ippcp.h
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 the
IppsAESSpec
context.
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 is
NULL
.
ippStsLengthErr
Indicates an error condition if the input data stream length is less than or equal to zero.
ippStsUnderRunErr
Indicates an error condition if
len
is not divisible by data block size.
ippStsContextMatchErr
Indicates an error condition if the context parameter does not match the operation.
