The Web Crypto API is defined entirely around asynchronous APIs that return promises, while the existing Node.js crypto module uses a combination of synchronous primitives, callbacks and stream APIs. Adopting Web Crypto into Node.js provides an additional promise-based approach that appeals to many developers.

Oct 29, 2014 · With the web slowly maturing as a platform the demand for cryptography in the browser has risen, especially in a post-Snowden era. Many of us have heard about the upcoming Web Cryptography API but 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. I was writing Symmetric Cryptography (AES) with WebCrypto and Node.js and I was going to include the WebCrypto examples inline, right alongside the Node.js examples, but then this happened and I cried myself to sleep.
