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 ECB functionality remains in the library, but it is not safe when used as is. Use any other mode, for example CBC.
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.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
