B_EncodeInit

int B_EncodeInit (
B_ALGORITHM_OBJ algorithmObject	/* algorithm object */
);

Description

B_EncodeInit initializes algorithmObject for encoding data using the algorithm specified by a previous call to B_SetAlgorithmInfo. For example, the AI_RFC1113Recode algorithm provides Base64 encoding and decoding to convert binary data to and from a printable form suitable for most email systems. Notice that there are no cryptographic keys for encoding or decoding.

only needs to be called once to set up an Encode algorithm. The B_EncodeUpdate routine can be called multiple times to process blocks of data, and B_EncodeFinal is called once to process the last block which includes adding any trailing pad bytes. After B_EncodeFinal is called, B_EncodeUpdate can be called to start decoding another sequence of blocks. There is no need to call

again.
