Generate self-signed PKCS#12 SSL certificate and export its keys using Java keytool and openssl.

Steps to generate self-signed PKCS#12 SSL certificate and export its keys:

1- Create PKCS#12 keystore (.p12 or .pfx file)

keytool -genkeypair -keystore myKeystore.p12 -storetype PKCS12 -storepass MY_PASSWORD -alias KEYSTORE_ENTRY -keyalg RSA -keysize 2048 -validity 99999 -dname "CN=My SSL Certificate, OU=My Team, O=My Company, L=My City, ST=My State, C=SA" -ext san=dns:mydomain.com,dns:localhost,ip:127.0.0.1
  • myKeystore.p12 = keystore filename. It can with .pfx extension as well.
  • MY_PASSWORD = password used for the keystore and the private key as well.
  • CN = commonName, it will be shown as certiciate name in certificates list.
  • OU = organizationUnit, department name for example.

Fetches the latest Linux Widevine binary so that it can be used by Vivaldi.

With the release of Vivaldi 2.2, this page is now obsolete and unmaintained. Widevine is fetched automatically on post install of our official packages. The information below and the script are left for historical reasons but will not be updated.
