I'm about to release an application in the Android Market. I need to generate a keystore to sign my application. The docs are a little spares on what I'm support to put into for the -dname param.

Here is the line I'm using:

keytool -genkey -v -alias release -keyalg RSA -keysize 2048 -dname "CN=mydomain.com" -keystore my.keystore -validity 10000

What is required in the -dname (Distinguished Name) field? I found out that I can include the CN field. Are there other fields that I must put in before the Market will accept the app? Any good optional ones to put in?

Updated I found out I can examine other apk's by using:

jarsigner -verify -verbose -certs nameof.apk

Here are some examples:

  • from http://slideme.org/ X.509, CN=SlideME, OU=SlideME, O=SlideME, L=Seattle, ST=WA, C=US
  • Opera Mini X.509, CN=Unknown, OU=Unknown, O=Opera Software ASA, L=Oslo, ST=Unknown, C=NO
  • Another random app, X.509, CN=Romeo Ordos, O=GHOR Corp., L=Donetsk, C=UA
