General iOS Server Configurations

Follow the instructions below to configure the iOS server-side configurations:

Generate an Apple Push Notification Service (APNS) certificate.

Follow the steps under the Configuring Push Notifications section to generate an APNS certificate.

Make a copy of the openssl.cnf file, move it to another location and edit the following:
The Certificate Authority (CA) and Registration Authority (RA) certificates should be created as version 3 certificates. This step is carried out for the latter mentioned purpose.

[ v3_req ] 
# Extensions to add to a certificate request 
basicConstraints=CA:TRUE 
keyUsage = Digital Signature, Key Encipherment 

[ v3_ca ] 
# Extensions for a typical CA 
# PKIX recommendation. 
subjectKeyIdentifier=hash 
authorityKeyIdentifier=keyid:always,issuer 
# This is what PKIX recommends but some broken software chokes on critical 
# extensions. 
basicConstraints = critical,CA:true 
# So we do this instead. 
#basicConstraints = CA:true 
# Key usage: this is typical for a CA certificate. However since it will 
# prevent it being used as an test self-signed certificate it is best 
# left out by default. 
keyUsage = Digital Signature, Certificate Sign, CRL Sign

Generate a self signed Certificate Authority (CA) certificate (version 3) and convert the certificate to the .pem format using the following commands:

It is assumed that the script is executed from the location where the modified openssl.cnf file was saved.
1. openssl genrsa -out <CA PRIVATE KEY> 4096
  For example: openssl genrsa -out ca_private.key 4096
2. openssl req -new -key <CA PRIVATE KEY> -out <CA CSR>
  For example: openssl req -new -key ca_private.key -out ca.csr
3. openssl x509 -req -days <DAYS> -in <CA CSR> -signkey <CA PRIVATE KEY> -out <CA CRT> -extensions v3_ca -extfile <PATH-TO-MODIFIED-openssl.cnf-FILE>
  For example: openssl x509 -req -days 365 -in ca.csr -signkey ca_private.key -out ca.crt -extensions v3_ca -extfile ./openssl.cnf
4. openssl rsa -in <CA PRIVATE KEY> -text > <CA PRIVATE PEM>
  For example: openssl rsa -in ca_private.key -text > ca_private.pem
5. openssl x509 -in <CA CRT> -out <CA CERT PEM>
  For example: openssl x509 -in ca.crt -out ca_cert.pem
Generate a Registration Authority (RA) certificate (version 3), sign it with the CA and convert the certificate to the .pem format using the following commands:

It is assumed that the script is executed from the location where the modified openssl.cnf file was saved.
1. openssl genrsa -out <RA PRIVATE KEY> 4096
  For example: openssl genrsa -out ra_private.key 4096
2. openssl req -new -key <RA PRIVATE KEY> -out <RA CSR>
  For example: openssl req -new -key ra_private.key -out ra.csr
3. openssl x509 -req -days <DAYS> -in <RA CSR> -CA <CA CRT> -CAkey <CA PRIVATE KEY> -set_serial <SERIAL NO> -out <RA CRT> -extensions v3_req -extfile <PATH-TO-MODIFIED- openssl.cnf-FILE>
  For example: openssl x509 -req -days 365 -in ra.csr -CA ca.crt -CAkey ca_private.key -set_serial 02 -out ra.crt -extensions v3_req -extfile ./openssl.cnf
4. openssl rsa -in <CA PRIVATE KEY> -text> <RA PRIVATE PEM>
  For example: openssl rsa -in ra_private.key -text > ra_private.pem
5. openssl x509 -in <RA CRT> -out <RA CERT PEM>
  For example: openssl x509 -in ra.crt -out ra_cert.pem
Generate the SSL certificate (version 3) based on your domain/IP address:

Your domain/IP address needs to be added as the Common Name, otherwise provisioning will fail.
1. Generate a RSA key.
  openssl genrsa -out <RSA_key>.key 4096
  For example:
  openssl genrsa -out ia.key 4096
2. Generate a CSR file.
  openssl req -new -key <RSA_key>.key -out <CSR>.csr
  For example:
  openssl req -new -key ia.key -out ia.csr
  Enter your server IP address/domain name (e.g., 192.168.1.157) as the Common Name else provisioning will fail.
3. Generate the SSL certificate
  openssl x509 -req -days 730 -in <CSR>.csr -CA ca_cert.pem -CAkey ca_private.pem -set_serial <serial number> -out ia.crt
  For example:
  openssl x509 -req -days 730 -in ia.csr -CA ca_cert.pem -CAkey ca_private.pem -set_serial 044324343 -out ia.crt
Export the SSL, CA and RA files as PKCS12 files with an alias.
1. Export the SSL file as a PKCS12 file with an "wso2carbon" as the alias.
  openssl pkcs12 -export -out <KEYSTORE>.p12 -inkey <RSA_key>.key -in ia.crt -CAfile ca_cert.pem -name "<alias>"
  For example:
  openssl pkcs12 -export -out KEYSTORE.p12 -inkey ia.key -in ia.crt -CAfile ca_cert.pem -name "wso2carbon"
2. Export the CA file as a PKCS12 file with an alias.
  openssl pkcs12 -export -out <CA>.p12 -inkey <CA private key>.pem -in <CA Cert>.pem -name "<alias>"
  For example:
  openssl pkcs12 -export -out ca.p12 -inkey ca_private.pem -in ca_cert.pem -name "cacert"
  In the above example, cacert has been used as the CA alias.
3. Export the RA file as a PKCS12 file with an alias.
  openssl pkcs12 -export -out <RA>.p12 -inkey <RA private key>.pem -in <RA Cert>.pem -chain -CAfile <CA cert>.pem -name "<alias>"
  For example:
  openssl pkcs12 -export -out ra.p12 -inkey ra_private.pem -in ra_cert.pem -chain -CAfile ca_cert.pem -name "racert"
  In the above example, racert has been used as the RA alias.
Copy the three P12 extension files to the <EMM_HOME>/repository/resources/security directory.
Import the generated P12 extension files as follows:
1. Import the generated <KEYSTORE>.p12 file into the wso2carbon.jks and client-truststore.jks in the <EMM_HOME>/repository/resources/security directory.
  keytool -importkeystore -srckeystore <KEYSTORE>.p12 -srcstoretype PKCS12 -destkeystore <wso2carbon.jks/client-truststore.jks>
  
  Ensure to enter the keystore password and keystore key password as wso2carbon
  For example:
  keytool -importkeystore -srckeystore KEYSTORE.p12 -srcstoretype PKCS12 -destkeystore wso2carbon.jks
  keytool -importkeystore -srckeystore KEYSTORE.p12 -srcstoretype PKCS12 -destkeystore client-truststore.jks
2. Import the generated <CA>.p12 and <RA>.p12 files into wso2EMM.jks in the <EMM_HOME>/repository/resources/security directory.
  keytool -importkeystore -srckeystore <CA/RA>.p12 -srcstoretype PKCS12 -destkeystore wso2mdm.jks
  
  For example:
  keytool -importkeystore -srckeystore ca.p12 -srcstoretype PKCS12 -destkeystore wso2mdm.jks
  Enter the keystore password as wso2carbon and the keystore key password as cacert.
  keytool -importkeystore -srckeystore ra.p12 -srcstoretype PKCS12 -destkeystore wso2mdm.jks
  Enter the keystore password as wso2carbon and the keystore key password as racert.
  Troubleshooting
  
  Why does the following error occur: "keytool error: java.io.IOException: Invalid keystore format"?
  If you enter the wrong private key password when importing the <CA>.p12 or <RA>.p12 files, the wso2emm.jks file will get corrupted and the above error message will appear.
  In such a situation, delete the wso2emm.jks file and execute the following command to import the generated <CA>.p12 and <RA>.p12 files into the wso2emm.jks file again.
  keytool -importkeystore -srckeystore <CA/RA>.p12 -srcstoretype PKCS12 -destkeystore wso2emm.jks
  
  When the above command is executed, WSO2 EMM will automatically create a new wso2emm.jks file with the imported file.

The default EMM keystore details are defined in the <CertificateKeystore> XML element. Therefore, if any of the following details are changed, it needs to be reflected in <CertificateKeystore> :

Certificate Keystore file location
Certificate Keystore type
Certificate Keystore password
Certificate authority certificate alias
Certificate authority private key password
Registration authority certificate alias
Registration authority private key password

Example:

<?xml version="1.0" encoding="ISO-8859-1"?>
<CertificateConfigurations>
    <CertificateKeystore>
        <!-- Certificate Keystore file location-->
        <CertificateKeystoreLocation>${carbon.home}/repository/resources/security/wso2certs.jks</CertificateKeystoreLocation>
        <!-- Certificate Keystore type (JKS/PKCS12 etc.)-->
        <CertificateKeystoreType>JKS</CertificateKeystoreType>
        <!-- Certificate Keystore password-->
        <CertificateKeystorePassword>wso2carbon</CertificateKeystorePassword>
        <!-- Certificate authority certificate alias -->
        <CACertAlias>cacert</CACertAlias>
        <!-- Certificate authority private key password -->
        <CAPrivateKeyPassword>cacert</CAPrivateKeyPassword>
        <!-- Registration authority certificate alias -->
        <RACertAlias>racert</RACertAlias>
        <!-- Registration authority private key password -->
        <RAPrivateKeyPassword>racert</RAPrivateKeyPassword>
    </CertificateKeystore>
</CertificateConfigurations>

After configuring the above obtain the signed CSR form and follow the proceeding step to complete the iOS server configurations.
