# 1. Generate the encryption Key
#
# This will save the *private* (secret) key to `private_key.age`
# and print the *public* (shareable) key to the terminal
age-keygen -o private_key.age

# 2. Send your public key to your co-conspirators via email or text

# 3. Save your co-conspirators' public keys to a file:
echo "age1ualzj2zuuja23xwmeldmmp669yylclpgnnvp8fj857qj55klh4ns620lxa" > robert.pubkey.age

# 4. Encrypt a file called `document.odf` for distribution
age -o encrypted_document.odt.age -R robert.pubkey.age document.odt

# 5. Email this file to your co-conspirators

# 6. Robert sends you a file called "hello.txt.age" and you want to decrypt it:
age -d -i private_key.age hello.txt.age

# 1. To set up ssh key:

# 4. Email this pub key to your collaborators
