Function Documentation

Eax_Decrypt()

WS_DLL_PUBLIC bool Eax_Decrypt	(	uint8_t *	pN,
		uint8_t *	pK,
		uint8_t *	pC,
		uint32_t	SizeN,
		uint32_t	SizeK,
		uint32_t	SizeC,
		MAC_T *	pMac,
		uint8_t	Mode
	)

Decrypts cleartext data using EAX' mode (see ANSI Standard C12.22-2008).

Parameters

[in]	pN	pointer to cleartext (canonified form)
[in]	pK	pointer to secret key
[in,out]	pC	pointer to ciphertext
[in]	SizeN	byte length of cleartext (pN) buffer
[in]	SizeK	byte length of secret key (pK)
[in]	SizeC	byte length of ciphertext (pC) buffer
[in]	pMac	four-byte Message Authentication Code
[in]	Mode	EAX_MODE_CLEARTEXT_AUTH or EAX_MODE_CIPHERTEXT_AUTH

Returns

true if message has been authenticated; false if not authenticated, invalid Mode or error
