Send me a secret

If you want to send me a secret like a password or some login details, follow these steps on an ubuntu machine:

echo "<your-secret-password>" > secretfile.txt

openssl rand -out secret.key 32

openssl aes-256-cbc -in secretfile.txt -out secretfile.txt.enc -pass file:secret.key

curl https://github.com/wipfli.keys > recipients-key.pub

openssl rsautl -encrypt -oaep -pubin -inkey <(ssh-keygen -e -f recipients-key.pub -m PKCS8) -in secret.key -out secret.key.enc

rm secret.key

Send me two files:

• secretfile.txt.enc
• secret.key.enc

How I will decrypt it

openssl rsautl -decrypt -oaep -inkey ~/.ssh/import-thinkpad/github_oliver/github_oliver -in secret.key.enc -out secret.key

openssl aes-256-cbc -d -in secretfile.txt.enc -out secretfile.txt -pass file:secret.key
