SL_CFB_Init int SL_CRYPTCALL SL_CFB_Init( void* pContext, int nDir, const void* pIV, unsigned int fs ); Return Value 1 if initializations was successful; otherwise 0. Parameters pContext [out] Pointer to the memory buffer that will be used as a context. nDir [in] Cipher direction. It can be SLC_ENCRYPT or SLC_DECRYPT. pIV [in] Pointer to the initialization vector. fs [in] Feedback size in bytes. Set fs to 0 if you want to use the maximum feedback size. This size is the mostly used feedback size. Remarks Initializes the context pointed by pContext with the initialization vector pointed by pIV. The context is initialized for encryption if nDir is SLC_ENCRYPT, or it is initialized for decryption if nDir is SLC_DECRYPT. Before calling the SL_CFB_Init function, allocate at least CONTEXTSIZE bytes for the context. For example, to perform Blowfish encryption/decryption allocate at least SLC_BLOWFISH_CONTEXTSIZE bytes for the context. Before calling SL_CFB_Init call the Init function of the encryption algorithm you need to use, passing to it the secret key and the cipher direction (SLC_ENCRYPT only). For example, to perform DES encryption/decryption in CFB mode call SL_DES_Init function before calling SL_CFB_Init. Example
