    - #### convertToDefiniteLength

          public static byte[] convertToDefiniteLength(byte[] berPKCS12File)
                                                throws java.io.IOException

      Just re-encode the outer layer of the PKCS#12 file to definite length encoding.
      Parameters:
        `berPKCS12File` - - original PKCS#12 file
      Returns:
        a byte array representing the DER encoding of the PFX structure
      Throws:
        `java.io.IOException`

    - #### convertToDefiniteLength

          public static byte[] convertToDefiniteLength(byte[] berPKCS12File,
                                       char[] passwd,
                                       java.lang.String provider)
                                                throws java.io.IOException

      Re-encode the PKCS#12 structure to definite length encoding at the inner layer as well, recomputing the MAC accordingly.
      Parameters:
        `berPKCS12File` - - original PKCS12 file.
        `provider` - - provider to use for MAC calculation.
      Returns:
        a byte array representing the DER encoding of the PFX structure.
      Throws:
        `java.io.IOException` - on parsing, encoding errors.
