Interface SSH2PKISigner

All Known Implementing Classes:

SSH2DSS, SSH2ECDSASHA2NIST, SSH2ECDSASHA2NIST.P256, SSH2ECDSASHA2NIST.P384, SSH2ECDSASHA2NIST.P521, SSH2RSA, SSH2Signature, SSH2SimpleSignature

public interface SSH2PKISigner

This interface is a simple abstraction of a PKI signing mechanism. An implementation of this interface can use certificates or plain public keys, this is something which is defined by the ssh2 specific algorithm name used to identify it.

Method Summary

Methods

Modifier and Type	Method and Description
void	clearSensitiveData() Try to remove any sensitive data from memory.
java.lang.String	getAlgorithmName() Get the algorithm name.
byte[]	getPublicKeyBlob() Get the public key blob encoded according to the ssh standard.
void	setIncompatibility(SSH2Transport transport) Set eventual incompatibility modes depending on the remote end.
byte[]	sign(byte[] data) Sign a blob of data.

Method Detail

getAlgorithmName

java.lang.String getAlgorithmName()

Get the algorithm name.

Returns:

The algorithm name.

getPublicKeyBlob

byte[] getPublicKeyBlob()
                        throws SSH2SignatureException

Get the public key blob encoded according to the ssh standard.

Returns:

A byte array containing the public key.

Throws:

SSH2SignatureException

sign

byte[] sign(byte[] data)
            throws SSH2SignatureException

Sign a blob of data.

Parameters:

data - The data to be signed.

Returns:

The signature, encoded according to the ssh standard.

Throws:

SSH2SignatureException

setIncompatibility

void setIncompatibility(SSH2Transport transport)

Set eventual incompatibility modes depending on the remote end. Some older ssh implementations use slightly incompatible algorithms when signing data.

Parameters:

transport - An SSH2Transport object which identifies the other end.

clearSensitiveData

void clearSensitiveData()

Try to remove any sensitive data from memory.
