Method Detail

encodePrivateKey

public static byte[] encodePrivateKey(AsymmetricKeyParameter params)
                               throws IOException

Encode a cipher parameters into an OpenSSH private key. This does not add headers like ----BEGIN RSA PRIVATE KEY----

Parameters:

params - the cipher parameters.

Returns:

a byte array

Throws:

IOException

parsePrivateKeyBlob

public static AsymmetricKeyParameter parsePrivateKeyBlob(byte[] blob)

Parse a private key.

This method accepts the body of the OpenSSH private key. The easiest way to extract the body is to use PemReader, for example:

byte[] blob = new PemReader([reader]).readPemObject().getContent(); CipherParameters params = parsePrivateKeyBlob(blob);

Parameters:

blob - The key.

Returns:

A cipher parameters instance.
