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);
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. |
