Rijndael256Init

Initializes user-supplied memory as IppsRijndael256Spec context for future use.

Syntax

IppStatus ippsRijndael256Init(const Ipp8u *pKey, IppsRijndaelKeyLength keylen, IppsRijndael256Spec* pCtx);

Parameters

pKey	Pointer to the Rijndael256 key.
keylen	Key byte stream length in bytes defined by the IppsRijndaelKeyLength enumerator.
pCtx	Pointer to the IppsRijndael256Spec context being initialized.

Description

This function is declared in the ippcp.h file. The function initializes the memory pointed by pCtx as the IppsRijndael256Spec context. In addition, the function uses the key to provide all necessary key material for both encryption and decryption operations.

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 keylen is not set to IppsRijndaelKey128, IppsRijndaelKey192 or IppsRijndaelKey256.
