Is there some tool to write out the actual content of a GnuPG public key in a way a human can unserstand? I mean not only ascii-armor which a human can read and type, but something which really breaks down the data into large decimal numbers for the crypto part, strings for the UIDs, and so on? I'd really like to see what's in there.
Actual application today: I've two keys from the same person, created at the same date, but differing in fingerprint. The assumption is that one of them was created from the other by some kind of conversion, probably by importing the older key into a keychaing using recent software. I'd like to see what actually changed. Perhaps it's only the fingerprinting algorithm which changed, but perhaps there is more to it.
