Method Detail

clonePublicKey

public net.i2p.crypto.eddsa.EdDSAPublicKey clonePublicKey(net.i2p.crypto.eddsa.EdDSAPublicKey key)
                                                   throws java.security.GeneralSecurityException

Parameters:

key - The PublicKey to clone - ignored if null

Returns:

The cloned key (or null if no original key)

Throws:

java.security.GeneralSecurityException - If failed to clone the key

clonePrivateKey

public net.i2p.crypto.eddsa.EdDSAPrivateKey clonePrivateKey(net.i2p.crypto.eddsa.EdDSAPrivateKey key)
                                                     throws java.security.GeneralSecurityException

Parameters:

key - The PrivateKey to clone - ignored if null

Returns:

The cloned key (or null if no original key)

Throws:

java.security.GeneralSecurityException - If failed to clone the key

getKeyPairGenerator

public java.security.KeyPairGenerator getKeyPairGenerator()
                                                   throws java.security.GeneralSecurityException

Returns:

A KeyPairGenerator suitable for this decoder

Throws:

java.security.GeneralSecurityException - If failed to create the generator

encodePublicKey

public java.lang.String encodePublicKey(java.io.OutputStream s,
                                        net.i2p.crypto.eddsa.EdDSAPublicKey key)
                                 throws java.io.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 KeyTypeNamesSupport.getSupportedKeyTypes()

Throws:

java.io.IOException - If failed to generate the encoding

getKeyFactoryInstance

public java.security.KeyFactory getKeyFactoryInstance()
                                               throws java.security.GeneralSecurityException

Returns:

A KeyFactory suitable for the specific decoder type

Throws:

java.security.GeneralSecurityException - If failed to create one

decodePublicKey

public net.i2p.crypto.eddsa.EdDSAPublicKey decodePublicKey(SessionContext session,
                                                           java.lang.String keyType,
                                                           java.io.InputStream keyData)

Parameters:

session - The SessionContext for invoking this command - may be null if not invoked within a session context (e.g., offline tool or session unknown).

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:

java.io.IOException - If failed to read from the data stream

java.security.GeneralSecurityException - If failed to generate the key

getSeedValue

public static byte[] getSeedValue(net.i2p.crypto.eddsa.EdDSAPublicKey key)
