org.conscrypt.ConnectionStateSSLv3

public class ConnectionStateSSLv3
extends ConnectionState

This class encapsulates the operating environment of the SSL v3 (http://wp.netscape.com/eng/ssl3) Record Protocol and provides relating encryption/decryption functionality. The work functionality is based on the security parameters negotiated during the handshake.

Constructor Details

ConnectionStateSSLv3

protected ConnectionStateSSLv3(SSLSessionImpl session)

Creates the instance of SSL v3 Connection State. All of the security parameters are provided by session object.

Parameters:

session - the sessin object which incapsulates all of the security parameters established by handshake protocol. The key calculation for the state is done according to the SSL v3 Protocol specification. (http://www.mozilla.org/projects/security/pki/nss/ssl/draft302.txt)

Method Details

encrypt

protected byte[] encrypt(byte type,
byte[] fragment,
int offset,
int len)

Creates the GenericStreamCipher or GenericBlockCipher data structure for specified data of specified type.

Specified by:

encrypt in class ConnectionState

Parameters:

type - - the ContentType of the provided data

fragment - - the byte array containing the data to be encrypted under the current connection state.

offset - - the offset from which the data begins with.

len - - the length of the data.

Throws:

AlertException - if alert was occurred.

decrypt

protected byte[] decrypt(byte type,
byte[] fragment,
int offset,
int len)

Retrieves the fragment of the Plaintext structure of the specified type from the provided data.

Specified by:

decrypt in class ConnectionState

Parameters:

type - - the ContentType of the data to be decrypted.

fragment - - the byte array containing the data to be encrypted under the current connection state.

offset - - the offset from which the data begins with.

len - - the length of the data.

Throws:

AlertException - if alert was occured.

shutdown

protected void shutdown()

Shutdown the protocol. It will be impossible to use the instance after the calling of this method.

Overrides:

shutdown in class ConnectionState
