AESDecryptECB
Decrypts byte data stream by using the AES algorithm in the ECB mode (deprecated).
Syntax
IppStatus ippsAESDecryptECB(const Ipp8u* pSrc, Ipp8u* pDst, int srclen, const IppsAESSpec* pCtx);
Include Files
ippcp.h
Parameters
pSrc |
Pointer to the input ciphertext data stream of variable length. |
pDst |
Pointer to the resulting plaintext data stream of variable length. |
srclen |
Length of the ciphertext data stream in bytes. |
pCtx |
Pointer to the IppsAESSpec context. |
Description
The function decrypts the input data stream of a variable length according to the ECB 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 output data stream length is less than or equal to zero. |
ippStsContextMatchErr |
Indicates an error condition if the context parameter does not match the operation. |
ippStsUnderRunErr |
Indicates an error condition if srclen is not divisible by cipher block size. |
