Method Detail

decodePrivateKey

public net.i2p.crypto.eddsa.EdDSAPrivateKey decodePrivateKey(String keyType,
                                                             FilePasswordProvider passwordProvider,
                                                             InputStream keyData)
                                                      throws IOException,
                                                             GeneralSecurityException

Parameters:

keyType - The reported / encode key type

passwordProvider - The FilePasswordProvider to use in case the data is encrypted - may be null if no encrypted data is expected

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 PrivateKey

Throws:

IOException - If failed to read from the data stream

GeneralSecurityException - If failed to generate the key

encodePrivateKey

public String encodePrivateKey(OutputStream s,
                               net.i2p.crypto.eddsa.EdDSAPrivateKey key)
                        throws IOException

Description copied from interface: PrivateKeyEntryDecoder

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

Parameters:

s - The OutputStream to write the data to

key - The PrivateKey - may not be null

Returns:

The key type value - one of the KeyEntryResolver.getSupportedTypeNames() or null if encoding not supported

Throws:

IOException - If failed to generate the encoding

isPublicKeyRecoverySupported

public boolean isPublicKeyRecoverySupported()

recoverPublicKey

public net.i2p.crypto.eddsa.EdDSAPublicKey recoverPublicKey(net.i2p.crypto.eddsa.EdDSAPrivateKey prvKey)
                                                     throws GeneralSecurityException

Description copied from interface: PrivateKeyEntryDecoder

Attempts to recover the public key given the private one

Parameters:

prvKey - The PrivateKey

Returns:

The recovered PublicKey - null if cannot recover it

Throws:

GeneralSecurityException - If failed to generate the public key

clonePublicKey

public net.i2p.crypto.eddsa.EdDSAPublicKey clonePublicKey(net.i2p.crypto.eddsa.EdDSAPublicKey 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 net.i2p.crypto.eddsa.EdDSAPrivateKey clonePrivateKey(net.i2p.crypto.eddsa.EdDSAPrivateKey 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
