BlockReadCipher

BlockReadCipher(Authenticator authenticator,
                ProtocolVersion protocolVersion,
                String algorithm,
                Key key,
                AlgorithmParameterSpec params,
                SecureRandom random)
         throws GeneralSecurityException

抛出:

GeneralSecurityException

方法详细资料

decrypt

public Plaintext decrypt(byte contentType,
                         ByteBuffer bb,
                         byte[] sequence)
                  throws GeneralSecurityException

指定者:

decrypt 在类中 SSLCipher.SSLReadCipher

抛出:

GeneralSecurityException

dispose

void dispose()

覆盖:

dispose 在类中 SSLCipher.SSLReadCipher

estimateFragmentSize

int estimateFragmentSize(int packetSize,
                         int headerSize)

指定者:

estimateFragmentSize 在类中 SSLCipher.SSLReadCipher

sanityCheck

private boolean sanityCheck(int tagLen,
                            int fragmentLen)

Sanity check the length of a fragment before decryption. In CBC mode, check that the fragment length is one or multiple times of the block size of the cipher suite, and is at least one (one is the smallest size of padding in CBC mode) bigger than the tag size of the MAC algorithm except the explicit IV size for TLS 1.1 or later. In non-CBC mode, check that the fragment length is not less than the tag size of the MAC algorithm.

返回:

true if the length of a fragment matches above requirements
