Creating your .keystore file to sign your Android APK

/in , /by

The APK signing process for android, although much simpler than iOS IPA signing, can still be another challenge for first time app developers. Again, it’s all about finding the right starting point, and syntax.

To Create our keystore We will use the keytool.exe included in the Java JDK. Open a command-line and navigate to your Java bin directory. For Windows 7, mine is located at
C:Program Files (x86)Javajre7bin
Next, run the following command. Be sure to replace the NAME & ALIAS with your values.
keytool -genkey -v -keystore [NAME HERE].keystore -alias [ALIAS NAME HERE] -keyalg RSA -keysize 2048 -validity 10000
The keytool will prompt you for the other required information for the keystore, Like Name, location, and password, but it’s all very basic.

That’s it. The .keystore file will be placed in your java bin directory, and you’re ready to go.

Sign iOS apps on a PC

The following information can be used to create profiles and certificates on a PC to sign a iOS app. Info in this post was taken from a great playlist of video instructions found at http://www.youtube.com/playlist?list=PL57C122F59F8F1A43

These operations require OpenSSL Fow Windows. You can get this at http://slproweb.com/products/Win32OpenSSL.html Download & install the Win32 or Win64 OpenSSL Light Client.

VARIABLES TO FIND/REPLACE
##PATH_TO_OPEN_SSL_BIN## - Ex: C:OpenSSL-Win64bin
##KEY_NAME## - Ex: reUrgencyMobileApp
##CONTACT_EMAIL## - Ex: apps@reUrgency.com
##CONTACT_NAME## - Ex: John Doe
##ENVIRONMENT## - Ex: Dev

Open a Command Prompt & cd to your OpenSSL bin directory

Run the following command to set your OpenSSL config path:

set OPENSSL_CONF=##PATH_TO_OPEN_SSL_BIN##openssl.cfg

Run the following command to create your Application Key

openssl genrsa -out ##KEY_NAME##.key 2048

Run the following command to create your Certificate Signing Requuest

openssl req -new -key ##KEY_NAME##.key -out ##KEY_NAME##_CSR.certSigningReq­uest -subj "/emailAddress=##CONTACT_EMAIL##, CN=##CONTACT_NAME##, C=US"

Run the following command to create your Signing Profile

openssl x509 -in ##KEY_NAME##_##ENVIRONMENT##.cer -inform DER -out ##KEY_NAME##_##ENVIRONMENT##.pem -outform PEM

Run the following command to create your .p12 signing certificate

openssl pkcs12 -export -inkey ##KEY_NAME##.key -in ##KEY_NAME##_##ENVIRONMENT##.pem -out ##KEY_NAME##_##ENVIRONMENT##.p12
