Key Pair Features. Generate RSA, EC and DSA key pairs with self-signed X.509 certificates. Apply X.509 certificate extensions to generated key pairs and Certificate Signing Requests (CSRs). Import key pairs from PKCS #12 files. Import key pairs from PKCS #8 private key/certificate combination files. If you would like to build and sign your app with your upload key, continue to the section about how to Sign your app with your upload key. If only want to generate the key and keystore, click Cancel. Sign your app with your key. If you already have an upload key, use it to sign your app.

1. May 26, 2019  Using Android KeyStore to generate a password. The code create a public/private key pair and uses the base64 encoded form of the certificate to as the password. The code modified the KeystoreHelper class from AOSP demo projects. KeyStoreHelper.java.
2. To generate a new public/private key pair in a Java keystore. Use the -genkeypair option to generate a key and save it to a Java keystore (newkeystore.jks in this example). The example shown here prompts you to enter values for items that make up the distinguished name (DN) in the certificate.

This procedure uses the Java keytool utility to generate a key and save it to a Java keystore.

NOTE:

• The CA you use might have specific options required for creating an HTTPS certificate. Review the instructions provided by the CA before creating your key pair.

• DSA keys used in Reflection Gateway server certificates must be either 2048 or 3072 bits. RSA keys must be between 2048 and 4096 bits.

To generate a new public/private key pair in a Java keystore

1. Use the -genkeypair option to generate a key and save it to a Java keystore (newkeystore.jks in this example). The example shown here prompts you to enter values for items that make up the distinguished name (DN) in the certificate. See the example below to enter these values directly on the command line.

2. The keytool prompts you to enter a password and values for the items that make up the distinguished name (DN) in the certificate (name = CN, organizational unit = OU, organization = O, city or locality = L, state or province = S, two letter country code = C). The generated DN will use the value 'Unknown' for any fields you don't specify.

   • When you are prompted with “What is your first and last name?'

     You must enter the DNS name that is used to access the Reflection Gateway server (for example gateway.mycompany.com). This value is used as the CN (Common Name) in the certificate. If the CN in a certificate doesn't match the actual DNS name used to access the server, you will see a certificate warning when you connect to the server.

   • When you are prompted with 'What is the two-letter country code for this unit?'

     You must enter a valid two-letter country code (for example US).

3. When you are prompted for a password for the alias, press Enter to use the same password you used for the keystore.

Android Keystore Example

An alternate option to responding to prompts is to specify the DN value on the command line using the -dname option. For example:

Generating a Key Pair and a Self-Signed Certificate

The genkey command of the keytool programenables you to generate a key pair.

To Generate a Key Pair and a Self-Signed Certificate

Generate Key Code

1. Navigate to the JAVA_HOME/bin directory,where JAVA_HOME is the installation directory ofthe Java SDK.

2. Enter the following command:

3. When prompted, enter your keystore password. Rsa_generate_key_ex in c.

4. When prompted, enter the Distinguished Name information.

   1. What is your first and last name?

      Caution –

      When prompted for your first and last name, make sureyou enter the machine hostname.

   2. What is the name of your organizational unit?

   3. What is the name of your organization?

   4. What is the name of your City or Locality?

   5. What is the name of your State or Province?

   6. What is the two-letter country code for this unit?

   7. Is CN=first_and_last_name, OU=organizational_unit, O=organization_name,L=city_or_locality, ST=state_or_province, C=two_letter_country_codecorrect?

5. When prompted, enter a password for the keystore entry.If the password is same as the keystore password, press Return.

   Note –

   Ifyou want to use a keystore, it is recommended to use the sbyn.keystore file in the JavaCAPS-install-dir/repository/repository/server directory.
