NETAESCreate

C Specification

#include <revolution/net.h>

BOOL NETAESCreate( NETAESContext *context, const void *key, u32 keylen, const void *iv );

Arguments

context	Pointer to the AES encryption context structure.
key	Key to use for AES encryption.
keylen	Length (in bytes) of the key. Choose between key lengths of 16 bytes (128 bits), 24 bytes (192 bits), and 32 bytes (256 bits).
iv	The 16-byte initial vector to use for AES encryption. The NET library only supports CBC mode for AES encryption.

Return Values

Returns TRUE if the AES encryption context has been generated correctly. Otherwise, returns FALSE.

Description

This function generates an AES encryption context. Make sure that this function is called before using NETAESEncrypt and NETAESDecrypt.
You must also call NETAESDelete to release the context after using these functions.

Note

To bolster the robustness of the encryption, the initial vector should be a random byte string, and a different value should be used for each set of plain text being encrypted.
The initial vector used at the time of decryption must be the same as the initial vector that is specified by this function at the time of encryption.
