                     throws IOException

Returns the object of generic type T that is pem encoded in the supplier.

Parameters:

supplier - the input stream factory

marker - header that begins the PEM block

processor - how to parser the object from a byte array

Returns:

the object of generic type T which was PEM encoded in the stream

Throws:

IOException - if an I/O error occurs

privateKeySpec
