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 the IppsSMS4Spec context. |
Description
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 len is not divisible by cipher block size. |
ippStsContextMatchErr |
Indicates an error condition if the context parameter does not match the operation. |
