BlowfishDecryptECB

Decrypts byte data stream according to Blowfish scheme in the EBC mode.

Syntax

IppStatus ippsBlowfishDecryptECB(const Ipp8u* pSrc, Ipp8u* pDst, int srclen, const IppsBlowfishSpec* pCtx, IppsCPPadding padding);

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 IppsBlowfishSpec context.
padding	IppsCPPaddingNONE padding scheme.

Description

This function is declared in the ippcp.h file. 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.
