<aside> ℹ️ If you want we can communicate encrypted. For this I provide some public keys which you can use to encrypt your files or messages. To check my public keys check my own site: mattiamueggler.ch/security

How to use my provided keys

RSA

Notice that the size is limited to 501 Bytes.

1. Safe your message in a file. echo "Hi, this is my encrypted message" >> message.txt
2. Encrypt this file and convert it to an base64 encoded text. openssl rsautl -encrypt -inkey mattiamueggler_public_key.pem -pubin -in message.txt -out encrypted_message.bin && base64 -i encrypted_message.bin >> encrypted_message.txt
3. Print the encoded value from your file. cat encrypted_message.txt
4. Send me either the value of this base64 encoded file or the file directly.

PGP

1. Install GnuPG
2. Import the public key from another person with: gpg --import mattia-at-mattiamueggler-ch_public.key
3. Safe your message in a file. echo "Hi, this is my encrypted message" >> message.txt
4. Encrypt the file by the mail your key is generated for: gpg -e -r [email protected] -o encrypted_output.txt message.txt
5. Send me either the value of this base64 encoded file or the file directly.

S/MIME

You don’t need to encrypt your message manually, like before. Download my certificate and add it to your keychain. (If I wrote you a mail before from my email address, your mail client probably stored my certificate automatically on your keychain.)
