Signing keys clarification needed

[kapitainsky]

Trying to sign AppImage with my pgp keys:

Embedding MD5 digest
gpg2 and sha256sum are installed and user requested to sign, hence signing
Error: cannot embed key in AppImage: size exceeds reserved ELF section size

Could not find any information about what keys are permitted, obviously mine is too long (4096 bits). Any details on this somewhere?

That's an issue for AppImageKit.

Just for your information, the size of the section to save a key is 8192 bytes, and it only saves the public key, not your private key (obviously, it should remain private; also, it would be 4096 bytes raw, but as it is wrapped with some metadata, storing it requires more space).
