• Mar 28, 2012  I'm writing this in the hopes that others may find this on Google. I had an issue that I'm using a v-for in Vue.js on a component, but in Vue 2.2+ you required:key to be set with a unique identifier. In my case the Array that it iterates over doesn't have any, so I had to generate one on demand (imagine a Bootstrap alerts manager component, e.g.).
• In RandomAPI, all of your fields are attached to the api object. A field is a Javascript property that holds the data that you want to generate and the api object is the central variable that RandomAPI will end up pushing into a results array. API Codeapi.age = random.numeric(1, 25); api.dogYears = api.age. 7.
• Extractable is a Boolean indicating whether it will be possible to export the key using SubtleCrypto.exportKey or SubtleCrypto.wrapKey. KeyUsages is an Array indicating what can be done with the newly generated key.

APIs are coded in Javascript and are very easy to make! An easy to use implementation, clean interface, and RESTful API make RandomAPI simple to use in all your applications. 'User 1', 'User 2', etc., you can generate random data that is custom tailored to your app that gives it a more realistic preview to how your product will look in. JavaScript exercises, practice and solution: Write a JavaScript program to display a random image (clicking on a button) from the following list.

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

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.

The Crypto.getRandomValues() method lets you get cryptographically strong random values. The array given as the parameter is filled with random numbers (random in its cryptographic meaning).

To guarantee enough performance, implementations are not using a truly random number generator, but they are using a pseudo-random number generator seeded with a value with enough entropy. The PRNG used differs from one implementation to the other but is suitable for cryptographic usages. Implementations are also required to use a seed with enough entropy, like a system-level entropy source.

getRandomValues() is the only member of the Crypto interface which can be used from an insecure context.

Syntax

Parameters

typedArray

An integer-based TypedArray, that is an Int8Array, a Uint8Array, an Int16Array, a Uint16Array, an Int32Array, or a Uint32Array. All elements in the array are overwritten with random numbers.

Return value

The same array passed as typedArrayÂ but with its contents replaced with the newly generated random numbers. Note that typedArray is modified in-place, and no copy is made.

Exceptions

This method can throw an exception under error conditions.

QuotaExceededError

The requested length exceeds 65,536 bytes.

Usage notes

Don't use getRandomValues() to generate encryption keys. Instead, use the generateKey() method. There are a few reasons for this; for example, getRandomValues() is not guaranteed to be running in a secure context.

There is no minimum degree of entropy mandated by the Web Cryptography specification. User agents are instead urged to provide the best entropy they can when generating random numbers, using a well-defined, efficient pseudorandom number generator built into the user agent itself, but seeded with values taken from an external source of pseudorandom numbers, such as a platform-specific random number function, the Unix /dev/urandom device, or other source of random or pseudorandom data.
