AESEncryptECB

Encrypts plaintext message by using ECB encryption mode (deprecated).

Syntax

IppStatus ippsAESEncryptECB(const Ipp8u *
pSrc
, Ipp8u *
pDst
, int
srclen
, const IppsAESSpec*
pCtx
);
Include Files
ippcp.h
Parameters
pSrc
Pointer to the input plaintext data stream of variable length.
pDst
Pointer to the resulting ciphertext data stream.
srclen
Length of the input plaintext data 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 encrypts the input data stream of a variable length according to the cipher scheme 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
srclen
is not divisible by cipher block size.
ippStsContextMatchErr
Indicates an error condition if the context parameter does not match the operation.
