Keymaster 1 implementations support the PKCS#8 format (without password protection) for importing RSA and EC key pairs, and support RAW import of AES and HMAC key material. Returns the list of export formats supported by the Keymaster hardware implementation of a specified algorithm. 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.

Secure context
This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

Use the generateKey() method of the SubtleCrypto interface to generate a new key (for symmetric algorithms) or key pair (for public-key algorithms).

Syntax

Parameters

• algorithm is a dictionary object defining the type of key to generate and providing extra algorithm-specific parameters.
  • For RSASSA-PKCS1-v1_5, RSA-PSS, or RSA-OAEP: pass an RsaHashedKeyGenParams object.
  • For ECDSA or ECDH: pass an EcKeyGenParams object.
  • For HMAC: pass an HmacKeyGenParams object.
  • For AES-CTR, AES-CBC, AES-GCM, or AES-KW: pass an AesKeyGenParams object.
• extractable is a Boolean indicating whether it will be possible to export the key using SubtleCrypto.exportKey() or SubtleCrypto.wrapKey().
• keyUsages Â is an Array indicating what can be done with the newly generated key. Possible values for array elements are:
  • encrypt: The key may be used to encrypt messages.
  • decrypt: The key may be used to decrypt messages.
  • sign: The key may be used to sign messages.
  • verify: The key may be used to verify signatures.
  • deriveKey: The key may be used in deriving a new key.
  • deriveBits: The key may be used in deriving bits.
  • wrapKey: The key may be used to wrap a key.
  • unwrapKey: The key may be used to unwrap a key.

Return value

• result is a Promise that fulfills with a CryptoKey (for symmetric algorithms) or a CryptoKeyPair (for public-key algorithms).

Exceptions

The promise is rejected when the following exception is encountered:

SyntaxError

Raised when the result is a CryptoKey of type secret or private but keyUsages is empty.

SyntaxError

Raised when the result is a CryptoKeyPair and its privateKey.usages attribute is empty.

Requirements

• An Android mobile app, Chrome app or extension, or an Amazon app. This is not for websites.
• A Google account
• A OneSignal Account, if you do not already have one.

Step 1: Create A Firebase Project

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. neat video premiere mac download

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.

Android Generate Aes Gcm Keyboard

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. 🥳
