Demonstrates the old way of encrypting/decrypting a string via Node.js crypto.createCipher and crypto.createDecipher, in addition to decrypting an older string that was generated via crypto.createCipher using the new crypto.createDecipheriv method.
It is strongly advised to generate a new encrypted string via crypto.createCipheriv...but sometimes that option isn't always available.
This should work with Node.js v10-18. Tested locally with v18.13.0.
Ensure all npm packages are installed by running: npm i
Three scripts are included:
"start:deprecated": "node ./crypto-legacy.js", -- runs deprecated encrypt/decrypt with createCipher and createDecipher
"start:decryptiv": "node ./crypto-legacy.js", -- runs deprecated encrypt createCipher but uses createDecipheriv to decrypt
"test": "mocha ./**/*.spec.js" -- unit tests showing the code works
