AESEncryptCBC

Encrypts byte data stream according to AES in the CBC mode.

Syntax

IppStatus ippsAESEncryptCBC(const Ipp8u* pSrc, Ipp8u* pDst, int len, const IppsAESSpec* pCtx, const Ipp8u* pIV);

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.
