SMS4EncryptECB
SMS4EncryptECB
Encrypts plaintext message by using ECB encryption mode (deprecated).
Syntax
IppStatus ippsSMS4EncryptECB(const Ipp8u *
pSrc
, Ipp8u *
pDst
, int
len
, const IppsSMS4Spec*
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.
- len
- Length of the input plaintext data in bytes.
- pCtx
- Pointer to theIppsSMS4Speccontext.
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 isNULL.
- ippStsLengthErr
- Indicates an error condition if the input data stream length is less than or equal to zero.
- ippStsUnderRunErr
- Indicates an error condition iflenis not divisible by cipher block size.
- ippStsContextMatchErr
- Indicates an error condition if the context parameter does not match the operation.
