I started writing code on a second-hand ZX Spectrum before I was 10, then moved to Visual Basic on Windows. At college I learned Turbo Pascal and Delphi. At university I worked with Ada and Java. Along the way, I have also used C, PHP, SQL, HTML, CSS, and a few other technologies.

I enjoy working where development, security, and operations meet. I care about using open source software to build a safer future, where commerce and collaboration can grow. I also enjoy keeping up with cryptography. I am exploring post-quantum cryptography and how it will affect modern IT systems.

Please encrypt sensitive files before sending them to me. I publish a GPG public key and an age-compatible SSH public key:

• GPG: https://github.com/richards-ensono.gpg
• age: https://github.com/richards-ensono.keys

1. Download the public key. Use the command for your shell:

   # curl
   curl -fsSLo richards-ensono.gpg https://github.com/richards-ensono.gpg
   
   # wget
   wget -qO richards-ensono.gpg https://github.com/richards-ensono.gpg

   # PowerShell
   Invoke-WebRequest -Uri https://github.com/richards-ensono.gpg -OutFile richards-ensono.gpg

2. Check that the fingerprint shown matches the one above, then import the key:

   gpg --show-keys --fingerprint richards-ensono.gpg
   gpg --import richards-ensono.gpg

3. Encrypt the file. This creates a text file that you can attach:

   gpg --armor --output message.txt.asc --encrypt \
     --recipient 0DD85D5AECA7F3C938320A35616702CCB034D739 \
     message.txt

4. Send message.txt.asc, not the original message.txt.

1. Download the age public key:

   # curl
   curl -fsSLo richards-ensono.keys https://github.com/richards-ensono.keys
   
   # wget
   wget -qO richards-ensono.keys https://github.com/richards-ensono.keys

   # PowerShell
   Invoke-WebRequest -Uri https://github.com/richards-ensono.keys -OutFile richards-ensono.keys

2. Encrypt the file with the public key:

   age --recipients-file richards-ensono.keys --output message.txt.age message.txt

3. Send message.txt.age, not the original message.txt.
