In WizarPOS terminals, app installation requires APK signature verification through the root certificate chain, in addition to the standard Android signature check. Only APKs signed with the root certificate or a child certificate are permitted. Developers must obtain a signing certificate from WizarPOS. Refer to for detailed application procedures.
A PC with Java Development Kit (JDK) installed.
Use the 'keytool' command in the JDK.
Ensure the domain name reflects your company's actual information.
CN

Set the 'EMAILADDRESS' to your company's official email.
For use in Eclipse as a custom debug keystore, set the alias to “androiddebugkey” and password to “android”. Otherwise, choose any alias and password.
Export CSR:
Follow the standard procedure to generate a CSR using keytool.
Submit CSR to WizarPOS:
Email the CSR with the following details:
Sales Person: Name of your WizarPOS contact.
Company Name: Your company's name.
Attachment: Include the CSR file.
Send to: WizarPOS sales staff (add first), support@wizarpos.com, team.support@wizarpos.com.
Save the WizarPOS reply (in *.crt or *.pem format) in the same folder as your keystore file.:
Store the Certificate File:
Save the *.pem file from WizarPOS's reply in the same directory as your keystore (jks) file. The filename will be as specified in the WizarPOS reply, referred to here as 'file-name-of-CSR-reply'.
Import the Certificate Chain:
Use the appropriate tool to import the certificate chain file into your keystore.
During the import process, when prompted to trust the certificate, select "Yes" or the equivalent affirmative option in your language.
Keytool Access
Location: 'keytool.exe' is found in the JRE directory, typically 'XXX/Java/jreXXX/bin'.
Usage:
If the 'JAVA_HOME' environment variable is set, 'keytool' can be run from any directory.
Without 'JAVA_HOME' set, you must navigate to the JRE directory to execute 'keytool' commands.
Resolving Keysize Issues during Keypair Generation
Solution:
Download the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files for your Java version:
Copy 'local_policy.jar' and 'US_export_policy.jar' into '$JAVA_HOME/jre/lib/security'.
CSR (Certificate Signing Request) Validation
Procedure:
Open the exported CSR in Notepad.
A valid CSR begins with "-----BEGIN NEW CERTIFICATE REQUEST-----" and ends with "-----END NEW CERTIFICATE REQUEST-----", with content in between.
If the CSR contains only an error message, address the specified issue as per the message.
Handling Expired Certificates
Renewal Process:
Email the expired certificate to support@wizarpos.com for renewal.
WizarPOS support will send back the renewed certificate.
Import the renewed certificate into the keystore that holds the expired certificate.
