Long time to encrypt/decrypt age secret files

[frlan]

I'm using batou 2.4.1

git:(master) ✗ cat requirements.txt 
batou==2.4.1
boto3
batou_ext>=2.4
ConfigUpdater==3.0.1

and using the age feature to encrypt/decrypt files

git:(master) ✗ ls -l environments/staging 
total 264

The process of simple open the secrets took quiet some time

git:(master) ✗ time ./batou secrets edit staging 
No changes from original cleartext. Not updating.
./batou secrets edit staging  13,84s user 0,49s system 39% cpu 36,478 total

In this case I did not save any changes -- however saving also takes some time.

While saving I'm getting

WARNING: The age encryption public-key metadata file has changed!
This means that some secrets are now encrypted with a different set of keys.
