Method Detail

readX509Certificate

public static X509Certificate readX509Certificate(InputStream in)
                                           throws IOException

Reads an X509Certificate PEM file from an InputStream.

Parameters:

in - InputStream to read the certificate from. The InputStream is closed after use.

Returns:

X509Certificate that was read

Throws:

IOException

writeX509Certificate

public static void writeX509Certificate(X509Certificate cert,
                                        OutputStream out)
                                 throws IOException

Writes an X.509 certificate PEM file.

Parameters:

cert - X509Certificate to write

out - OutputStream to write the PEM file to. The OutputStream is closed after use.

Throws:

IOException

writeX509Certificate

public static void writeX509Certificate(X509Certificate cert,
                                        Writer w)
                                 throws IOException
