vite+vue3 uses aes-cross to report: TypeError: crypto.createCipheriv is not a function Version: "vue": "^3.2.23", "vite": "^2.6.4", "aes-cross": "^1.0.9",
The function crypto.createCipheriv
is a node.js only function meaning it is not available in the browser like in a Vue app. You should look into SubtleCrypto
which provides native web features for many encryption purposes like AES. As always, it should be noted that one should be very careful and methodical when using low-level crypto primitives, especially regarding encryption. This page provides more examples of AES encryption specifically.
To get crypto
working in browser, follow instructions bellow
yarn add stream-browserify browserify-zlib events process util buffer
vite.config.js
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
// https://vitejs.dev/config/
export default defineConfig({
plugins: [vue()],
resolve: {
alias: {
process: "process/browser",
stream: "stream-browserify",
zlib: "browserify-zlib",
util: 'util'
}
}
})
