generateKey(algorithm:String, extractable:Bool, keyUsages:Array<String>):Promise<Dynamic>

Returns a Promise of a newly generated CryptoKey, for symmetrical algorithms, or a CryptoKeyPair, containing two newly generated keys, for asymmetrical algorithm, that matches the algorithm, the usages and the extractability given as parameters.

Throws:

null

DOMError

importKey(format:String, keyData:Dynamic, algorithm:Dynamic, extractable:Bool, keyUsages:Array<String>):Promise<Dynamic>

importKey(format:String, keyData:Dynamic, algorithm:String, extractable:Bool, keyUsages:Array<String>):Promise<Dynamic>

Returns a Promise of a CryptoKey corresponding to the format, the algorithm, the raw key data, the usages and the extractability given as parameters.
