certificates Android

Sign an apk
java -jar out/host/linux-x86/framework/signapk.jar -w .x509.pem .pk8 app_name.apk app_name-signed.apk

How can I check that an Android apk is signed with a release and not debug cert?
$ jarsigner -verify -verbose -certs my_application.apk

.509.pem is the Certificate
.pk8 is the hash

content of a pem file
$ openssl x509 -in acs.qacafe.com.pem -text



jar -xvf ../foo.jar
cd META-INF
openssl pkcs7 -in TEST.RSA -print_certs -inform DER -out foo.cer


keytool -printcert -file ANDROID_.RSA
keytool -list -keystore my-signing-key.keystore
