Method Detail

getPublicKeyBlob

public byte[] getPublicKeyBlob()

Description copied from class: KeyPair

Returns the blob of the public key.

Overrides:

getPublicKeyBlob in class KeyPair

Returns:

blob of the public key

getKeyType

public int getKeyType()

Description copied from class: KeyPair

returns the type of the keys in this keypair, which is one of KeyPair.RSA and KeyPair.DSA.

Specified by:

getKeyType in class KeyPair

getKeySize

public int getKeySize()

getSignature

public byte[] getSignature(byte[] data)

Specified by:

getSignature in class KeyPair

getVerifier

public Signature getVerifier()

Specified by:

getVerifier in class KeyPair

forSSHAgent

public byte[] forSSHAgent()
                   throws JSchException

Specified by:

forSSHAgent in class KeyPair

Throws:

JSchException

dispose

public void dispose()

Description copied from class: KeyPair
