Decrypt an RSA message from browser with window.crypto.subtle APIs

由 雨燕双飞 提交于 2020-04-30 04:28:51
问题 I'm trying to decode an RSA 2048 bit message encoded with a public key using the corresponding private key. The environment is google chrome and I'm using the window.crypto.subtle APIs. I generated the key couple and encoded the message using openssl tools: # generate keys and put the private one in file private_key.pem openssl genpkey -algorithm RSA -out private_key.pem -pkeyopt rsa_keygen_bits:2048 # extract public key in file public_key.pem openssl rsa -pubout -in private_key.pem -out

How to get HMAC with Crypto Web API

由 岁酱吖の 提交于 2020-03-17 10:50:28
问题 How can I get HMAC-SHA512(key, data) in the browser using Crypto Web API ( window.crypto )? Currently I am using CryptoJS library and it is pretty simple: CryptoJS.HmacSHA512("myawesomedata", "mysecretkey").toString(); Result is 91c14b8d3bcd48be0488bfb8d96d52db6e5f07e5fc677ced2c12916dc87580961f422f9543c786eebfb5797bc3febf796b929efac5c83b4ec69228927f21a03a . I want to get rid of extra dependencies and start using Crypto Web API instead. How can I get the same result with it? 回答1: Answering my

How to use Jest to test functions using crypto or window.msCrypto

由 陌路散爱 提交于 2020-01-01 19:45:34
问题 When running unit tests with Jest in react the window.crypto API is causing problems. I haven't found a way to incorporate crypto in Jest without installing other packages which is something I can't do. So without using another npm package is there a way to test functions that use: crypto.getRandomValues() in them that doesn't crash Jest? Any links, advice, or tips are appreciated 回答1: This should do it. Use the following code to set up the crypto property globally. This will allow Jest to

What is wrong with crypto.getRandomValues in Internet Explorer 11?

问题 The following code generates 3 random numbers by using window.crypto.getRandomValues . According to the developer's documentation (Microsoft MSDN and Mozilla MDN), this should work both in IE and in Chrome. But in reality it works only in Chrome, not Internet Explorer 11. According to Microsoft, this code should work - they have given a similar code sample as the one listed below (see MSDN link above). What is wrong? And how can it be fixed so it will work in both browsers? var

js signature on chrome with OS keystore

W3C is working on a http://www.w3.org/TR/WebCryptoAPI/ to define a way to generate digital signatures, encrypton and so on from javascript. Basically defines a new object crypto inside a window object in DOM which must provide javascript with signature and encrypton features. Chrome starts to implement this object which is currently available in its javascript engine (I think in beta stage), I make some tries to generate some signatures with it an seems to work correctly, however I think the most util way to generate digital signatures with this new object is using the private keys in the OS
