On any Windows computer, you can use the Certificates MMC snap-in to create custom certificate signing requests, including wildcard and multi-SAN certificates for web server authentication. How do make a custom certificate signing request. First open the Certificates MMC snap-in. Steps to create RSA private key, self-signed certificate, keystore, and truststore for a client. Generate a private key. Openssl genrsa -out diagclientCA.key 2048. Create a x509 certificate. Openssl req -x509 -new -nodes -key diagclientCA.key -sha256 -days 1024 -out diagclientCA.pem. Create PKCS12 keystore from private key and public certificate. Android keystore system The Android Keystore system lets you store cryptographic keys in a container to make it more difficult to extract from the device. Once keys are in the keystore, they can be used for cryptographic operations with the key material remaining non-exportable.

This article covers the creation of a new Java keystore using Java keytool.
Process
Or, you can check the step by step guidelines below.
1. Create a new keystore:
Open a command prompt in the same directory as Java keytool; alternatively, you may specify the full path of keytool in your command. Pay close attention to the alias you specify in this command as it will be needed later on.
keytool -genkey -alias mydomain -keyalg RSA -keystore KeyStore.jks -keysize 2048
2. Generate a CSR based on the new keystore:
keytool -certreq -alias mydomain -keystore KeyStore.jks -file mydomain.csr
Answer each question when prompted. Use the chart below to guide you through the process:

Field | Example |
---|---|
First & Last Name | Domain Name for SSL Certificates Entity Name for Code Signing |
Organizational Unit | Support (Optional, e.g. a department) |
Organization | GMO GlobalSign Inc (Entity's Legal Name) |
City / Locality | Portsmouth (Full City name) |
State / Province | New Hampshire (Full State Name) |
Country Code | US (2 Letter Code) |
Confirm or reject the details by typing 'Yes' or 'No' and pressing Enter
Press Enter to use the same password as the keystore, alternatively specify a separate password and press enter.
You should now have a file called mydomain.csr which can be used to order or reissue a digital certificate from GlobalSign.
3. While the order processes, download the root & intermediate certificates for your order. You can identify the correct root & intermediate certificate based on hash algorithm and product type.
4. Import the root & intermediate certificates into your keystore. Import the root certificate first, followed by the intermediate. Make sure you specify the correct alias of 'root' and 'intermediate' respectively.
keytool -import -trustcacerts -alias root -file root.crt -keystore KeyStore.jks
keytool -import -trustcacerts -alias intermediate -file intermediate.crt -keystore KeyStore.jks
5. Download & import your new certificate
Download your new certificate; save it as mydomain.crt.
Use the same alias as the private key so it associates them together. The alias here must match the alias of the private key in the first command.
keytool -import -trustcacerts -alias mydomain -file mydomain.crt -keystore KeyStore.jks
The keystore is now complete and can be used for signing code or deploying on a Java based web server depending on the product you ordered.
