Can I use your source code in my commercial software?

[kippler]

I made a commercial software (of course not an open-source software) and want to support AESCrypt format.

I understand GNU-GPL License and replace all GPLed aes/sha256 code to Gladman's AES(http://www.gladman.me.uk/cryptography_t ... leencrypt/) with this code.

Code: Select all

#define sha256_context				sha256_ctx
#define sha256_starts				sha256_begin
#define sha256_update(a,b,c)		sha256_hash(b,c,a)
#define sha256_finish(ctx,digest)	sha256_end(digest, ctx)

typedef aes_encrypt_ctx aes_context;


inline void  _aes_set_key_e( aes_context *ctx, unsigned char *key, int nbits )
{
	int keyLen = nbits/8;
	aes_init();
	aes_encrypt_key(key, keyLen, ctx);
}


inline void  _aes_set_key_d( aes_context *ctx, unsigned char *key, int nbits )
{
	int keyLen = nbits/8;
	aes_init();
	aes_decrypt_key(key, keyLen, (aes_decrypt_ctx*)ctx);
}


inline void _aes_encrypt( aes_context *ctx, const unsigned char input[16], unsigned char output[16] )
{
	aes_encrypt((const unsigned char*)input, (unsigned char*)output, ctx);
}


inline void _aes_decrypt( aes_context *ctx, const unsigned char input[16], unsigned char output[16] )
{
	aes_decrypt((const unsigned char*)input, (unsigned char*)output, (aes_decrypt_ctx*)ctx);
}

But, I still use your code(aescrypt.h/c) and have some questions.

- When I see the license of aescrypt.c, It looks like not a GPLed code. Then, can I use your code(aescrypt.h/cpp) in my commercial-software?

- If I can't use your code, I want to implement a new code that compatible with your Aescrypt format. Is it allowed?


I so appreciate your software and very sorry to try earning money with it.

Yeah, the rest of the code has always been totally free, so you are welcome to use it in a commercial product.
