Add support for keys with subkeys only about pgpro HOT 4 OPEN

Thanks reporting this!
Importing the secret key in private.gpg-key.txt triggers an assertion failure in the cryptography framework:

2020-07-20 19:58:40.439760+0200 PGPro[35698:1882528] *** Assertion failure in -[PGPSecretKeyPacket buildSecretKeyDataAndForceV4:], /Users/marcinkrzyzanowski/Devel/ObjectivePGP/ObjectivePGP/Packets/PGPSecretKeyPacket.m:354
2020-07-20 19:58:40.458873+0200 PGPro[35698:1882528] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Require IV'

It seems that ObjectivePGP doesn't find an initialization vector in the key packet. I'll try and look further into this.

Thanks for replying so quickly!
Ok, this seems to me, that it is rather a problem with the ObjectivePGP library than in the app? Would it be better to open an issue there?
By the way: if you need the passphrase for the secret key posted above, it's: "very secure passphrase!" (without the quotes but with whitespace and exclamation mark).

Hello Luca,
Many thanks for your app. I realize that the bug report I mailed to you on April 21st was probably about the same problem.
Best regards
Pascal

Details :

• The app crashes each time I try to import my personal keys (exported into an .asc file through gpg keychain (MacOS Catalina).
• The asc file is copied to the iPhone through a usb cable using MacOS finder.
• My keys includes : one main pair of keys, three subkeys for signing, encrypting, authenticating, all using RSA 4096.
• The crash only occurs when the main secret key is not present in the .asc file.
• When both the secret key and subkeys are present, all is fine.
• iPhone X, iOS 14.4.2

Thank you @craisp and @SailingDad! Good news: I've now finally been able to fix this issue. Bad news: Keys with subkeys only are still not supported (because the cryptography framework can't handle them), but at least the app won't crash anymore.
