This will very often be on a very untrusted network, such as a free wifi network you found in some random place. In this lab we'll set up your MTA to accept encrypted incomming connections, so that it won't matter what sort of network your workstation computer or phone is connected to. 800px|border|center Sadly tod..."

• 13:0213:02, 1 August 2023 diff hist +10,381‎ N OPS345 Lab 7 Newversion ‎ Created page with "= Email services components = Originally there was only one "email" protocol: SMTP. It was designed to address, route, and receive messages for a destination user on a destination server. Later an extra couple of protocols (POP3 and IMAP) were developed so that people wouldn't have to read their email on the command-line on the SMTP server. Now there are many components, making a powerful, reliable, but complex system. Here's a simplified diagram of what typically happen..."

The cyphertext created by a good encryption algorithm is impossible (or, for weak algorithms: at least impractical) to decrypt (covert back into plain text) without a key. You've been using public key cryptography for your entire life (unless you were born before the 1990s). And you've been setting up public key cryptograph..."
• 11:2411:24, 1 August 2023 diff hist +8,613‎ N OPS345 Lab 5 Newversion ‎ Created page with "= DNS overview = The Domain Name System converts human-friendly domain names to IP addresses. Computers on the internet can only communicate with each other using IP addresses. But people aren't very good at remembering long strings of numbers (up to 12 digits for ipv4) or even longer strings of numbers and characters mixed (24 characters for ipv6). Therefore DNS is a critical part of the internet infrastructure, and just about everyone who has a website needs to do so..."

It won't be even close to production-ready but you will get more practice with the basics, which is what you need most now. This assignment assumes that your www.youruserid.ops345.ca is a working web server. If you didn't complete that part of Lab 3: you'll need to do it first. The format of the assignment is similar to a lab..."

Only people in the Matrix can look at a stream of binary data and see pictures. Real people need a library to convert that stream of data to RGB values for pixels in XY coordinates, and a video card to place those on a screen. The same applies to apparently simple data like strings of text. You could store text as AS..."
