Apologies if this question is not in the right place.

I've recently been looking through some RSA certificates ( specifically, Android apk .rsa files) and I'm having trouble deciphering the one and two letter combinations in the Owner/Issuer lines.

ex: CN, OU, O, L, ST, C

L, ST, and C are Location, State and Country, I think, but what are the others?

Look for X500 and X.509 – CodesInChaos Mar 21 '13 at 20:27

CN is common name, OU is orginizational unit, O = organization.

So we could have CN="John Johnson", OU="Sales", O="Acme Corp." or something like that. only mentions these, but I've seen Email as well.

Are there any additional entries(?) that could show up on those lines? – Phill.Zitt Feb 19 '13 at 18:40
