Description

Is your feature request related to a problem? Please describe. I need to protect the user's information, and the business requires us to use symmetric encryption. But I found that SHADOWNODE does not support symmetric encryption.

Describe the solution you'd like Like node.js, it supports cipher and related symmetric encryption functions such as crypto.createCipheriv(algorithm, key, iv[, options])

Describe alternatives you've considered Use napi to supplement symmetric encryption with c++

Research direction
Examine the existing crypto module implementation in ShadowNode (likely in src/ or deps/). Look at how Node.js implements crypto.createCipheriv in its C++ layer using OpenSSL. The issue suggests using N API to add symmetric encryption; study N API examples in the repo. Check if there are any linked PRs or discussions. Implement the cipher initialization and update/final methods, wrapping OpenSSL EVP cipher functions. Test with known vectors.
