Rijndael192Init

Initializes user-supplied memory as the IppsRijndael192Spec context for future use.

Syntax

IppStatus ippsRijndael192Init(const Ipp8u *pKey, IppsRijndaelKeyLength keylen, IppsRijndael192Spec* pCtx);

Parameters

pKey	Pointer to the Rijndael192 key.
keylen	Key byte stream length in bytes as defined by the IppsRijndaelKeyLength enumerator.
pCtx	Pointer to the IppsRijndael192Spec context.

Description

This function is declared in the ippcp.h file. The function initializes the memory pointed by pCtx as the IppsRijndael192Spec context. In addition, the function uses the key to provide all the 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.
