Mar 28, 2017 Cyphr - Encrypted messaging simplified. Cyphr makes encrypted messaging easy. All messages are encrypted, private and 100% yours. Generate your public and private key pair so only you can read your messages, start group conversations with friends, and share attachments privately. ONLY YOU CAN READ YOUR MESSAGES. Cyphr generates a unique public and private key pair so only you and your friend. Add your SSH private key to the ssh-agent and store your passphrase in the keychain. If you created your key with a different name, or if you are adding an existing key that has a different name, replace idrsa in the command with the name of your private key file. $ ssh-add -K /.ssh/idrsa.

What is a Firebase Server Key?
A Firebase Server Key and Firebase Sender ID are required in order to send push notifications to Android mobile app devices.
The goal of this section is to provision your Firebase Server Key and Firebase Sender ID for use in OneSignal.
Requirements
Step 1: Create A Firebase ProjectGoogle Private Browsing
If you already have an FCM project you would like to use with OneSignal, you will need to retrieve your Sender ID and Firebase Cloud Messaging token. You may then skip to Step 2.
Visit the Firebase Console and sign in with your Google account.
Click CREATE NEW PROJECT or select an existing one below.
Enter a project name and press CREATE PROJECT.
Step 2: Getting Your Firebase Cloud Messaging Token And Sender ID
Click the gear icon in the top left and select Project settings.
Select the CLOUD MESSAGING tab.
Save the two values listed under Server key and Sender ID.
Step 3: Configure Your OneSignal App's Android Platform Settings
In the OneSignal dashboard, select your app from the All Apps page, then go to Settings. Under Native App Platforms, click Google Android.
Paste your Firebase Server Key and Firebase Sender ID into the fields and click Save.
Done! You now have a key to send push notifications from your app. 🥳
Next, install the OneSignal SDK in your app. If you need help, we have a few SDK-specific guides:
What's Next
Step 1: Verify that you have
openssl installed.
If not, install
openssl using:
If you are using Microsoft(r) Windows, checkout http://gnuwin32.sourceforge.net/packages/openssl.htm for details about the
openssl package on Windows.
If you using Linux, you can use the default package manager to get the
openssl package installed on your box. For example:
Step 2: Create a RSA private key.
server.key is a PEM RSA private key. To know more about what is a PEM file and it’s significance, read What is a Pem file and how does it differ from other OpenSSL Generated Key File Formats? at serverfault.com.
Step 3: Create the Certificate Signing Request (CSR) utilizing the RSA private key we generated in the last step.
The ‘challenge password’ is used by the Certificate Authority (CA) to authenticate the certificate owner when they have to revoke the certificate. There is no way to revoke a Self-Signed Certificate via Certificate Revocation List (CRL) (refer: https://devcenter.heroku.com/articles/ssl-certificate-self#generate-private-key-and-certificate-signing-request]
As a result of executing the above command, you will find a file named
server.csr (‘csr’ stands for Certificate Signing Request) in the same directory.
Step 4: Generate a file named,
v3.ext with the below listed contents:
This step is required because when you load the certificate in the Chrome browser, it would display an error portrayed in the below screenshot.
Setting the
DNS.1 value in v3.ext file to be same as the Common Name that you mentioned while generating the certificate signing request would resolve the error. Refer https://stackoverflow.com/questions/43665243/chrome-invalid-self-signed-ssl-cert-subject-alternative-name-missing for more details about the subject alternate name missing error and the solution.
The above command will use the Certificate Signing Request and the RSA Private Key that we generated as part of executing the previous steps and generate a Certificate file named,
server.crt (‘crt’ is an abbreviation of ‘Certificate’) and place it in the same directory.
Step 5: Import the newly generated certificate in your Keychain (Mac OSX only).
Since this is a self-signed certificate, the browser would display a warning mentioning that the certificate is self-signed and the website should not be trusted as portrayed in the below-listed screenshot captured on the Chrome browser.
Click the
Advanced hyperlink at the bottom of the warning page and click Proceed to hyperlink.
The browser will allow you to proceed and open the homepage but will mark the site as
Not-Secure as portrayed in the image below.
To avoid this accepting the self-signed certificate everytime you restart chrome or restart your web server, follow the steps outlined at Google Chrome, Mac OS X and Self-Signed SSL Certificates to add the certificate to your Mac OSX Keychain. Restart Chrome.
Other platforms like Microsoft(r) Windows and Linux have similar techniques to import a certificate into a browser. A quick Google(r) search should be able to provide you with the exact steps based on the browser that you use.
Now Chrome should happily display the green ‘Secure’ icon against the URL when you navigate to your locally deployed website. Also, the
Security tab within the Developer Tools should list the site as ‘Secure’ as portrayed in the screenshot below.
