decodePrivateKey

public net.i2p.crypto.eddsa.EdDSAPrivateKey decodePrivateKey(SessionContext session,
                                                             java.lang.String keyType,
                                                             FilePasswordProvider passwordProvider,
                                                             java.io.InputStream keyData)
                                                      throws java.io.IOException,
                                                             java.security.GeneralSecurityException

Parameters:

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

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:

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

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

encodePrivateKey

public java.lang.String encodePrivateKey(java.io.OutputStream s,
                                         net.i2p.crypto.eddsa.EdDSAPrivateKey key)
                                  throws java.io.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 KeyTypeNamesSupport.getSupportedKeyTypes() or null if encoding not supported

Throws:

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

isPublicKeyRecoverySupported

public boolean isPublicKeyRecoverySupported()

recoverPublicKey

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:
