Decrypts a ciphertext buffer using the given ARC4 parameters and key.

Synopsis:

#include "huarc4.h"

int hu_ARC4DecryptMsg(sb_Params arc4Params, sb_Key arc4Key, size_t length, const unsigned char *ciphertext, unsigned char *plaintext, sb_GlobalCtx sbCtx)

Since:

BlackBerry 10.0.0

Arguments:

arc4Params: An ARC4 parameters object.

arc4Key: An ARC4 key object.

length: The length (in bytes) of ciphertext.

ciphertext: The ciphertext buffer.

plaintext: The plaintext buffer.

sbCtx: A global context.

Library:

libhuapi (For the qcc command, use the -l huapi option to link against this library)

Description:

This function should only be called for buffers of plaintext and ciphertext that can be stored entirely in memory.

Returns:

SB_ERR_NULL_PARAMS: The arc4Params parameters object is NULL.

SB_ERR_BAD_PARAMS: The tag for the params object is not of the expected type.

SB_ERR_NULL_KEY: The arc4Key object is NULL.

SB_ERR_BAD_KEY: The arc4Key object is invalid.

SB_ERR_NULL_INPUT_BUF: The ciphertext buffer is NULL.

SB_ERR_BAD_INPUT_BUF_LEN: The length of the ciphertext buffer is invalid.

SB_ERR_NULL_OUTPUT_BUF: The plaintext buffer is NULL.

SB_SUCCESS: Success.
