I want to know if my usage of the web crypto API is sensible. I want to use it for symmetric and public-key encryption and decryption, and signatures, but as a non-expert I am scared by the warning on the MDN page: Warning: The Web Crypto API provides a number of low-level cryptographic primitives.

Here's a sample on how to use CryptoJs in webclient: // INIT var myString = "blablabla Card game bla"; var myPassword = "myPassword"; // PROCESS var encrypted = CryptoJS.AES.encrypt (myString, myPassword); var decrypted = CryptoJS.AES.decrypt (encrypted, myPassword); document.getElementById ("demo0").innerHTML 7/10/2018 Crypto APIs supports 3 ways to manage private keys: Use a wallet already generated by you or that you will generate in a more secure way, sign the transaction on your side and send it to us. This means we will never get the private key. Generate a wallet/address using our API, we will generate both public and private keys and will return them to you. 3/6/2021 You can use crypto.subtle.exportKey to convert the keys into many different exportable formats and then export them. Similarly you can use crypto.subtle.importKey to convert the exported keys into an key objects for use. Here is an sample code showing how to import and export the generated private key window.crypto.subtle.wrapKey( "jwk", //can be "jwk", "raw", "spki", or "pkcs8" key, //the key you want to wrap, must be able to export to above format wrappingKey, //the AES-CFB key with "wrapKey" usage flag { … If finalCode exists, the certificate request object is returned to this Javascript method.
