Detailed Description

A utility class that decrypts data. This stores the current decryption state so it can be reused for a single decrypt operation. This will only succeed if all the data is decrypted, meaning for CBC, a whole AES block needs to be given. It is assumed the output is at least the same size as the input.

Member Function Documentation

§ Decrypt()

bool shaka::util::Decryptor::Decrypt	(	const uint8_t *	data,
		size_t	data_size,
		uint8_t *	dest
	)

Decrypts the given data into the given buffer. This data size must be a multiple of AES_BLOCK_SIZE.

Definition at line 113 of file decryptor_darwin.cc.

§ DecryptPartialBlock()

bool shaka::util::Decryptor::DecryptPartialBlock	(	const uint8_t *	data,
		size_t	data_size,
		uint32_t	block_offset,
		uint8_t *	dest
	)

Decrypts the given partial block into the given buffer. This must be given a partial block and |data_size + block_offset <= AES_BLOCK_SIZE|.
