pgp
If you want to share credentials with me you can encrypt them with my public key using PGP.
In case you don't have PGP installed, you can paste the credentials in the next textarea and hit the "Encrypt" button. The text will then get encrypted using my public key. The encryption happens locally on your machine using OpenPGP.js. The unencrypted input never leaves your machine.
After pressing "Encrypt" you'll have to copy the result from the output textarea and send it to me via a different communication channel.
