Constructor Details

Session

protected Session()
The basic constructor. Object is special, because it has no superclass, so there is no call to super().

Returns this session's cihper suite.
Specified by:
getCipherSuite in interface SSLSession
Returns:
The cipher suite.

getCreationTime

public long getCreationTime()
Returns the time in milliseconds since midnight GMT, 1 January 1970, that this session was created.
Specified by:
getCreationTime in interface SSLSession
Returns:
The creation time.

getId

public byte[] getId()
Returns this session's unique identifier, a arbitrary byte array of up to 32 bytes.
Specified by:
getId in interface SSLSession
Returns:
The session identifier.

getLastAccessedTime

public long getLastAccessedTime()
Returns the last time this session was accessed.
Specified by:
getLastAccessedTime in interface SSLSession
Returns:
The lest time this session was accessed.

getLocalCertificates

public Certificate[] getLocalCertificates()
Returns the chain of certificates that the local side used in the handshake, or null if none were used.
Specified by:
getLocalCertificates in interface SSLSession
Returns:
The local certificate chain.

getLocalPrincipal

public Principal getLocalPrincipal()
Returns the Principal representing the local identity used in this session, or null if there is no local identity.
Specified by:
getLocalPrincipal in interface SSLSession
Returns:
The local principal.

getPacketBufferSize

public int getPacketBufferSize()
Returns the size of the largest SSL message that will be generated by this session.

Callers of wrap and unwrap should use this value to determine the size of buffers for data coming into, or going out over, the network.

Specified by:
getPacketBufferSize in interface SSLSession
Since:
1.5

getPeerCertificateChain

public X509Certificate[] getPeerCertificateChain()
            throws SSLPeerUnverifiedException
Returns the chain of certificates that the remote side used in the handshake, or null if none were used.
Specified by:
getPeerCertificateChain in interface SSLSession
Returns:
The peer's certificate chain.
Throws:
SSLPeerUnverifiedException - If the identity of the peer has not been verified.

getPeerCertificates

public Certificate[] getPeerCertificates()
            throws SSLPeerUnverifiedException
Returns the chain of certificates that the remote side used in the handshake, or null if none were used.
Specified by:
getPeerCertificates in interface SSLSession
Returns:
The peer's certificate chain.
Throws:
SSLPeerUnverifiedException - If the identity of the peer has not been verified.

getPeerHost

public String getPeerHost()
Returns the remote host's name.
Specified by:

The peer's port number.
Since:
1.5

getPeerPrincipal

public Principal getPeerPrincipal()
            throws SSLPeerUnverifiedException
Returns the Principal representing the identity of the remote peer, or null if the remote peer has no known identity.
Specified by:

Get the private data of this session. This method may only be called after first calling prepare(char[]).
Returns:
The sealed private data.
Throws:
SSLException - If the private data have not been sealed.

putValue
