Support the generation of an age key via Golang library

[ChrisJBurns]

Not sure if this is possible currently (I've had a go to see if it's possible), but I would really love the ability to generate an age key in Golang.

Otherwise I'm having to call the age-keygen command line, which is flaky because that means I have to read the file that was created and read the public-key in order to start encrypting things.

Example of using exec to run age-keygen:

	cmd := exec.Command("age-keygen", "-o", "age.agekey")
	stdout, err := cmd.Output()

	if err != nil {
		fmt.Println(err)
		return
	}

What would be better

publicKey, privateKey := ageKeygen.GenerateKeys()

So apologies from me. I raised this issue because I saw that the generate() method in the age-keygen module is private - which is why I raised the issue. To make it somewhat public or accessible to users. But I inspected the actual method itself and saw that it called age.GenerateX25519Identity(). So I had a gander at that (as it is public), and saw that I could use it to create the pub and priv keys.

My solution for others who are wondering same thing is the following:

My Solution

import 	(
    "filippo.io/age"
)
identity, err := age.GenerateX25519Identity()
if err != nil {
fmt.Println(err)
return
}
fmt.Println(identity.String())
fmt.Println(identity.Recipient().String())

Output was then the keys that you would get in the age.agekey file if using the following command age-keygen -o age.agekey.

Output

AGE-SECRET-KEY-1K3LYN3MGC379XKNUZT0GRX9DNHZGPZS7E48GPM5CRWV3CXMMGT6SZYWN7N
