I found I needed to import them as two subkeys of the same key, rather than separate split keys.

I had them in NSStrings (secKeyArmorSecret, and secKeyArmorPublic), but the concept is the same:

secKey=[[PGPKey alloc] initWithSecretKey:[[ObjectivePGP readKeysFromData: [secKeyArmorSecret dataUsingEncoding:NSUTF8StringEncoding] error:&error] objectAtIndex:0].secretKey publicKey:[[ObjectivePGP readKeysFromData:[secKeyArmorPublic dataUsingEncoding:NSUTF8StringEncoding] error:&error] objectAtIndex:0].publicKey];

[ozobken]

Hmm -

SIGSUBPKT_ISSUER_FPR = 33, /* Issuer fingerprint. */

• Also could just be that your GnuPG keys contain packets that are indeed not supported

[kllmctrl]

I found that Tests/PGPTests.m

case testSigningSubKey and testIssue91Tag9

I use test testIssue62 it work in my iOS app, using issue62-keys.asc. How should I gen keys and export pub,sec keys on OSX system.

[ozobken]

I generate my keys from Objective PGP:

PGPKeyGenerator *generator = [[PGPKeyGenerator alloc] init];
    secKey = [generator generateFor:UID passphrase:nil];

33 is currently unsupported, and experimental. It's part of draft specification: https://datatracker.ietf.org/doc/html/draft-ietf-openpgp-rfc4880bis-10#section-5.2.3.28
