The all-in-one ultimate online toolbox that generates all kind of keys! Every coder needs All Keys Generator in its favorites! It is provided for free and only supported by ads and donations. Whenever we save data in Firebase, it generates a unique identification ID for each object. Sometimes it's hard to maintain or traverse the data on the basis of these randomly generated IDs, because the only way to access data in Firebase is via URL reference (refObject/books//title) for the particular node.

Angular: 1.5.3

Firebase: 3.0

AngularFire: 2.0.1

This is my old method:

New method?

commented Jun 7, 2016

There's no AngularFire code here. Not really sure how this relates to the bindings lib.

For an example of the API usage of push(), see here.

key is now a read-only property, not a function. So, you would do this:

var newAppKey = appRef.push().key;

See here for the full list of changed methods.

Generate Random Key In Firebase Keys Key

KeysThis class provides the functionality of a secret (symmetric) key generator.

Key generators are constructed using one of the getInstance class methods of this class.

KeyGenerator objects are reusable, i.e., after a key has been generated, the same KeyGenerator object can be re-used to generate further keys.

There are two ways to generate a key: in an algorithm-independent manner, and in an algorithm-specific manner. The only difference between the two is the initialization of the object:

  • Algorithm-Independent Initialization

    All key generators share the concepts of a keysize and a source of randomness. There is an init method in this KeyGenerator class that takes these two universally shared types of arguments. There is also one that takes just a keysize argument, and uses the SecureRandom implementation of the highest-priority installed provider as the source of randomness (or a system-provided source of randomness if none of the installed providers supply a SecureRandom implementation), and one that takes just a source of randomness.

    Since no other parameters are specified when you call the above algorithm-independent init methods, it is up to the provider what to do about the algorithm-specific parameters (if any) to be associated with each of the keys.

  • Algorithm-Specific Initialization

    For situations where a set of algorithm-specific parameters already exists, there are two init methods that have an AlgorithmParameterSpec argument. One also has a SecureRandom argument, while the other uses the SecureRandom implementation of the highest-priority installed provider as the source of randomness (or a system-provided source of randomness if none of the installed providers supply a SecureRandom implementation).

In case the client does not explicitly initialize the KeyGenerator (via a call to an init method), each provider must supply (and document) a default initialization.

Every implementation of the Java platform is required to support the following standard KeyGenerator algorithms with the keysizes in parentheses:

  • AES (128)
  • DES (56)
  • DESede (168)
  • HmacSHA1
  • HmacSHA256
These algorithms are described in the KeyGenerator section of the Java Cryptography Architecture Standard Algorithm Name Documentation. Consult the release documentation for your implementation to see if any other algorithms are supported.
