Method Detail

decodePublicKey

public DSAPublicKey decodePublicKey(String keyType,
                                    InputStream keyData)
                             throws IOException,
                                    GeneralSecurityException

Specified by:

decodePublicKey in class AbstractPublicKeyEntryDecoder<DSAPublicKey,DSAPrivateKey>

Parameters:

keyType - The reported / encode key type

keyData - The key data bytes stream positioned after the key type decoding and making sure it is one of the supported types

Returns:

The decoded PublicKey

Throws:

IOException - If failed to read from the data stream

GeneralSecurityException - If failed to generate the key

encodePublicKey

public String encodePublicKey(OutputStream s,
                              DSAPublicKey key)
                       throws IOException

Description copied from interface: PublicKeyEntryDecoder

Encodes the PublicKey using the OpenSSH format - same one used by the decodePublicKey method(s)

Parameters:

s - The OutputStream to write the data to

key - The PublicKey - may not be null

Returns:

The key type value - one of the PublicKeyEntryDecoder.getSupportedTypeNames()

Throws:

IOException - If failed to generate the encoding

clonePublicKey

public DSAPublicKey clonePublicKey(DSAPublicKey key)
                            throws GeneralSecurityException

Parameters:

key - The PublicKey to clone - ignored if null

Returns:

The cloned key (or null if no original key)

Throws:

GeneralSecurityException - If failed to clone the key

clonePrivateKey

public DSAPrivateKey clonePrivateKey(DSAPrivateKey key)
                              throws GeneralSecurityException

Parameters:

key - The PrivateKey to clone - ignored if null

Returns:

The cloned key (or null if no original key)

Throws:

GeneralSecurityException - If failed to clone the key

getKeyPairGenerator

public KeyPairGenerator getKeyPairGenerator()
                                     throws GeneralSecurityException

Returns:

A KeyPairGenerator suitable for this decoder

Throws:

GeneralSecurityException - If failed to create the generator

getKeyFactoryInstance

public KeyFactory getKeyFactoryInstance()
                                 throws GeneralSecurityException

Returns:

A KeyFactory suitable for the specific decoder type

Throws:

GeneralSecurityException - If failed to create one
