Reads the certificate's private key from the stream. The key should be contained in NET format.
0 on success.
PKCS#8 error code otherwise.
Use this method to read the certificate's private key from the stream. The read operation is started at current stream position and finished when the end of the stream reached or when the number of bytes specified in Count parameter is read. The private key must have been saved in NET format.
NET format was invented by Microsoft Corp. and is based on PKCS#8 private key format. However, it is not fully compatible with PKCS#8, so passing a buffer with raw PKCS#8 data will cause an 'invalid format' error.
