en.wikipedia.org/wiki/… and more specifically en.wikipedia.org/wiki/OCB_mode are relatively recent advances that provide more robust integrity protection against possible tampering of your data than the standard-OpenPGP MDC (Manipulation Detection Code), but for data you don't exchange with other people/systems (and I sure hope you aren't sending your password file to other people!) this is probably unnecessary. If you want to go into this in more detail, security.SX is probably more suitable. ...– dave_thompson_085Commented Mar 4 at 0:58

... Note this is independent of the keypair(s). You can use AEAD/OCB on any of RSA DSA/EG or ECC keypairs, and you can use not-AEAD/OCB on any of them. Ed25519 cannot encrypt, but is usually used with a cv25519 subkey; as long as your systems (all) support these, they are considered quite secure.– dave_thompson_085Commented Mar 4 at 1:03

Thanks for the hints. I'll ask at security.SX additionally as you advised.– Tobias LeupoldCommented Mar 4 at 6:27

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. windows-7), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
