privateKeyFromPkcs8

public static PrivateKey privateKeyFromPkcs8(String privateKeyPkcs8)
                                      throws IOException

Converts a PKCS#8 string to an RSA private key.

Parameters:

privateKeyPkcs8 - the PKCS#8 string.

Returns:

the RSA private key.

Throws:

IOException - if the PKCS#8 data is invalid or if an unexpected exception occurs during key creation.

privateKeyFromPkcs8

public static PrivateKey privateKeyFromPkcs8(String privateKeyPkcs8,
 com.google.auth.oauth2.OAuth2Utils.Pkcs8Algorithm algorithm)
                                      throws IOException
