How dangerous it is to share public keys and share information which keys is used to encrypt file?

Hi,
I'm thinking of sharing secrets in team based on age. But In order to identify who is the owner of the secret, re-encrypt, I am trying save information about plain public keys used to encrypt file.

There's a mention about this in README. But I'm not a security expert and not sure how much dangerous it is to share plain recipients(public key).

Note that SSH key support employs more complex cryptography, and embeds a public key tag in the encrypted file, making it possible to track files that are encrypted to a specific public key.

Sorry for stupid question.

There are no stupid questions, only incomplete docs :)

There is no risk in storing public keys with encrypted files, except the obvious ones: it will be possible to know what files were encrypted to what keys, and it will be possible to re-encrypt different files to those keys.

Thanks! Always love to see your work!
