Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

Update Finch

Update finch to version 1.25 or newer.

Material Animations

[Android Transition Framework][transition-framework] can be used for three main things:

Animate activity layout content when transitioning from one activity to another.
Animate shared elements (Hero views) in transitions between activities.
Animate view changes within same activity.

I'm learning about SOPS and setting it up as my preferred mechanism for storing secrets. Here are my notes.

PGP

It’s security mechanism is that we (i.e. client) use a PUBLIC key from the receiver (i.e. server) and encode it with a random key (I’m saying nonce but it could be reused)

This varies from RSA and SSH because the server uses a PUBLIC key to identify the client.

Web of trust

Web of trust operates by still using PGP (i.e. encoding with recipient’s public key) but additionally, we can encrypt/sign the data as our own by signing it with the client’s private key.

This means the recipient will initially decrypt via our (i.e. client’s) public key (verifying the source) and then decrypting via their (i.e. server’s) private key to get the data.

Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

openssl genrsa -des3 -out rootCA.key 4096
