Constructor & Destructor Documentation

shaka::media::AesCbcEncryptor::AesCbcEncryptor ( CbcPaddingScheme padding_scheme )

explicit

Creates a AesCbcEncryptor with continous cipher block chain across Crypt calls, i.e. AesCbcEncryptor(padding_scheme, kDontUseConstantIv).

Parameters

padding_scheme indicates the padding scheme used. Currently supported schemes: kNoPadding, kPkcs5Padding, kCtsPadding.

Definition at line 99 of file aes_encryptor.cc.

shaka::media::AesCbcEncryptor::AesCbcEncryptor	(	CbcPaddingScheme	padding_scheme,
		ConstantIvFlag	constant_iv_flag
	)

Parameters

padding_scheme	indicates the padding scheme used. Currently supported schemes: kNoPadding, kPkcs5Padding, kCtsPadding.
constant_iv_flag	indicates whether a constant iv is used, kUseConstantIv means that the same iv is used for all Crypt calls until iv is changed via SetIv; otherwise, iv is updated internally and there is a continuous cipher block chain across Crypt calls util iv is changed explicitly via SetIv or UpdateIv functions.
