Method Details

getChannelType

public String getChannelType()

setChannelType

public void setChannelType(String channelType)

getExecutorService

public CloseableExecutorService getExecutorService()

Specified by:

getExecutorService in interface ExecutorServiceCarrier

getIdentities

public Iterable<? extends Map.Entry<PublicKey,String>> getIdentities()
                                                              throws IOException

Specified by:

getIdentities in interface SshAgent

Throws:

IOException

sign

public Map.Entry<String,byte[]> sign(SessionContext session,
 PublicKey key,
 String algo,
 byte[] data)
                              throws IOException

Specified by:

sign in interface SshAgent

Parameters:

session - The current SessionContext

key - The PublicKey to use for signing

algo - Recommended signature algorithm - if null/empty then one will be selected based on the key type and/or signature factories. Note: even if specific algorithm specified, the implementation may disregard and choose another

data - Data to sign

Returns:

used algorithm + signed data - using the identity

Throws:

IOException - If failed to sign

addIdentity

public void addIdentity(KeyPair kp,
 String comment,
 SshAgentKeyConstraint... constraints)
                 throws IOException

Description copied from interface: SshAgent

Adds a key to the agent.

Specified by:

addIdentity in interface SshAgent

Parameters:

kp - KeyPair to add

comment - to associate with the key

constraints - SshAgentKeyConstraints for this key to pass on to the agent

Throws:

IOException - if an error in the communication with the agent occurred, or the agent did not return a reply indicating successful addition of the key

removeIdentity

                    throws IOException

Specified by:

removeIdentity in interface SshAgent

Throws:
