Manual Decryption

Encrypted content is stored in code blocks with language set to age. For example:

-----BEGIN AGE ENCRYPTED FILE-----
YWdlLWVuY3J5cHRpb24ub3JnL3YxCi0+IHNjcnlwdCBrUWE0cmIxOFA3NUNXK3d1
V25pT1Z3IDE4ClBaMFY5NWc3bjZIMUxSNHRYSm9FUHMxamdsWjJ3UlhPZjM0R1pm
WFEzOEkKLS0tIHkwaFZNbmQybndaa2dxMkpxdUpOR01uZUQwK21oaSszai9hWnB3
ejJHaW8KxIr7k/vxvgqX0Dqun83t1yyupFW4JOYLzS9uwRSo5OxhCqf88SvxXbs=
-----END AGE ENCRYPTED FILE-----

You can always save this to a file and decrypt your content using the age CLI tool:

# Install age CLI tool first
age -d secret.age
