[Czino]

I encountered an error on iOS (at least 14.5)

I am trying to verify a signature of following message (IBAN is a fake number I got from here )

{"id":"sepa-IE29AIBK93115212345678","type":"sepa","iban":"IE29 AIBK 9311 5212 3456 78","beneficiary":"Czino"}

Signature is the following

When verifying the signature in react, following error is thrown:

Error: boolResponse: signature error: openpgp: unsupported feature: unknown critical signature subpacket type 33
To make sure the signature itself is indeed correct, I imported the pubKey to my gpg keychain and verified the signature via gpg --verify which yields a good result

In react, I use the following to sign and verify:
const signature = await OpenPGP.sign(message, publicKey, privateKey, '')

and

await OpenPGP.verify(signature, message, publicKey)

$ gpg --verify message.txt.asc
