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
You should use the distinguished name that corresponds to your company. Here is a list of the types of components that you can use:
As far as I know, you can use a complete Distinguised Name separating each component by a comma. For instance, in your case you could use: CN=christophercotton.com,L=Franklin.
As far as I know, those information are not used/display by Google Play.
