TDESEncryptECB
Encrypts variable length data stream in ECB mode (deprecated).
Syntax
IppStatus ippsTDESEncryptECB(const Ipp8u *pSrc, Ipp8u *pDst, int length, const IppsDESSpec *pCtx1, const IppsDESSpec *pCtx2, const IppsDESSpec * pCtx3, IppsCPPadding padding);

Parameters
pSrc |
Input plaintext data stream of a variable length. |
pDst |
Resulting ciphertext data stream. |
length |
Input data stream length in bytes. |
pCtx1 |
First set of round keys scheduled for TDES internal operations. |
pCtx2 |
Second set of round keys scheduled for TDES internal operations. |
pCtx3 |
Third set of round keys scheduled for TDES internal operations. |
padding |
IppsPaddingNONE padding scheme. |
Description
This function encrypts the input data stream of a variable length according to the cipher scheme specified in NIST SP 800-38A. The function uses three sets of supplied round keys in the ECB mode. The function returns the ciphertext result.
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 the input data stream length is not divisible by cipher block size. |
ippStsContextMatchErr |
Indicates an error condition if the context parameter does not match the operation. |
