		const uint8_t *	src,
		int	count,
		uint8_t *	iv,
		int	decrypt
	)

Encrypt or decrypt a buffer using a previously initialized context.

Parameters

ctx	an AVXTEA context
dst	destination array, can be equal to src
src	source array, can be equal to dst
count	number of 8 byte blocks
iv	initialization vector for CBC mode, if NULL then ECB will be used
decrypt	0 for encryption, 1 for decryption
