# create a PEM pub key (will be useful later)
openssl rsa -in .ssh/id_rsa -pubout -out id_rsa.pub.pem
# check it
chmod 700 id_rsa.pub.pem
openssl rsa -in id_rsa.pub.pem -pubin -text -noout

# 1) encrypt small file, using only RSA private and pub key 
# create a secret
echo "my secret" > secret.txt
# encrypt the file using your public key

# file encryption using private and public key : the recipent public key is used in this case
alice$ gpg --output secret.bin --encrypt --recipient bob.public.key secret.txt
bob$ gpg --output secret.txt --decrypt secret.txt

# file encryption without using priv/pub key
gpg --output secret.bin --symmetric --cipher-algo AES256 secret.txt
gpg --output secret.txt --decrypt secret.bin
