Syntax

IppStatus ippsARCFive128Init (const Ipp8u *pKey, int keylen, int rounds, IppsARCFive128Spec* pCtx);

Parameters

pKey	Pointer to the RC5 key.
keylen	Key byte stream length in bytes.
rounds	The number of rounds for the cipher.
pCtx	Pointer to the IppsARCFive128Spec context.

Description

This function is declared in the ippcp.h file. The function initializes the memory pointed by pCtx as the IppsARCFive128Spec 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.
