Pass-through Authentication on an IIS Intranet site

We wish to use Single Sign On  to pass Windows Authentication through our Intranet site called LibPrograms.

Firstly, we need enable Windows Authentication in IIS. In   IIS / Sites / LibPrograms / Authentication set as follows:
  • Anonymous Authentication: disabled
  • Windows Authentication: Enabled
Secondly, add LibPrograms site to Local Intranet:
  • IE 11
- Internet Option / Security / Local Intranet / Sites / Check Automatically detect intranet work / Advanced / Manually add this site to Local Intranet

- Check Custom Level for Local Intranet: scroll down to the bottom, in User Authentication section, make sure Automatic logon only in Intranet zone is selected.

Note: there is no such settings in IE Edge - so called "modern" browsers.
  • Chrome
Settings / Advanced /Search "proxy" / click Open proxy settings / this is the same one settings as in IE 11

Use GnuPG Tools or C# Code for PGP Encryption and Signature

For PGP encryption and signature, usually we use PGP command line tools for test purpose and finally use C# application for production. Mine is a Net Core 2.0 console application using NuGet package PgpCore,  https://github.com/mattosaurus/PgpCore. PgpCore is based on BouncyCastle.NetCore which supports the standard OpenPGP keys. Here w use the popular GnuPG (GPG) tools to generate OpenPGP key pair. Download and Install GPG for Windows Download from  https://gpg4win.org/download.html . By default the installation will create two folders (here we use command line tools only): Gpg4Win UI (Kleopatra): C:\Program Files (x86)\Gpg4win Command line tools: C:\Program Files (x86)\GnuPG\bin Generate a GPG Key Pair For GnuPG 2.2.1 and above:     C:\Program Files (x86)\GnuPG\bin> gpg --full-generate-key For old versions of GnuPG:     C:\Program Files (x86)\GnuPG\bin> gpg --gen-key Common GPG Commands List public keys: gpg --list-key or gpg -k List private keys: gpg

Confusing Concepts about SFTP: SSH2 vs OpenSSH

Credit and copied from https://dada.tw/2008/01/03/70/ Terminology: SSH Protocols and Products SSH A generic term referring to SSH protocols or software products. SSH-1 The SSH protocol, Version 1. This protocol went through several revisions, of which 1.3 and 1.5 are the best known, and we will write SSH-1.3 and SSH-1.5 should the distinction be necessary. SSH-2 The SSH protocol, Version 2, as defined by several draft standards documents of the IETF SECSH working group. SSH1 Tatu Ylönen's software implementing the SSH-1 protocol; the original SSH. Now distributed and maintained (minimally) by SSH Communications Security, Inc. SSH2 The "SSH Secure Shell" product from SSH Communications Security, Inc. This is a commercial SSH-2 protocol implementation, though it is licensed free of charge in some circumstances. ssh (all lowercase letters) A client program included in SSH1, SSH2, OpenSSH, F-Secure SSH, and other
