I'm adding support for multiple public keys per actor in Smithereen for future-proofing purposes.

@silverpill are we allowing Mastodon guide ActivityPub development again, when alternatives exist?

@grishka yeah, you need to let the crypto library autodetect the type of key. OpenSSL manages to do it:
curl -s https://federated.id/actors/a1517c06-7131-4437-84b0-025837e9da39 | jq -r .publicKey.publicKeyPem | openssl pkey -pubin -text
@mariusor Java's built-in crypto API can't do that unfortunately as far as I know. I guess I'll have to try every supported type on every key until I find one that works

@silverpill yep. Your bane, more JSON-LD bullshit.

@silverpill yep. Your bane, more JSON-LD bullshit.
@grishka@mariusor @silverpill Smithereen is one of the few ActivityPub implementations that actually uses JSON-LD contexts not just for LD signatures but also when parsing data, so not a problem for me in particular

@grishka it should be. The ASN package that gets encoded to PEM should have the algorithm value set:
curl -s https://federated.id/actors/a1517c06-7131-4437-84b0-025837e9da39 | jq -r .publicKey.publicKeyPem | openssl asn1parse

@silverpill I see... Got a link to that, I should update my stuff...

@silverpill nevermind, I found it in the FEP.
