Saving environment variables in gopass

How can I save environment variables (sensitive) in gopass and retrieve them and set in my bash terminal them from command line.

I know this can be done in 1password where the password are stored:

myaccount

• key1 - value1
• key2 - value2
• key3 - value3

Internally this is in json format and can be pull with a command like:

   op get item "myaccount" | jq .
 
   source <(op get item ${1} | jp -r --arg key2 "${2} '.details.section[] | 
   select(.title==$title) | .fields[0].v' | base64 -D ")

The whole idea is my environment variables must be set in a automate way from a secure vault rather than me exporting them like this:

export key1=value1
export key2=value2
export key3=value3

This is a bit of a late answer, but you could save them into gopass like this:

echo $key1 | gopass insert store/environment/key1

Or if you need them to be base64 ecoded:

echo $key1 | base64 -w 0 | gopass insert store/environment/key1

Then you could source them still using export, but sourcing them from gopass, rather than hard coding them.

key1=$(gopass store/environment/key1)

key1=$(gopass store/environment/key1 | base64 -d)
