Node.JS Ciphers Info in version 15.x

After the deprecation of methods createCipher(…) and createDecipher(…) due to the introduction of createCipheriv(…) and createDecipheriv(…) a lot of us had issues when specifying the keys and IVs because sometimes the key would be the incorrect size and same for the IVs. I developed a kind of brute force tester to determine the correct values and keep them in a JSON file but honestly it was not ideal.

Today I was having a look at Crypto’s documentation and I saw that for version 15.x of Node.JS there is a method that gives us that information. It’s called getCipherInfo(…) and here’s how to use it:

const crypto = require('crypto');
crypto.getCiphers().forEach((cipher) => {
    // console.log(cipher);
    console.log(crypto.getCipherInfo(cipher)); // Added in: v15.0.0
});

The console output maybe similar to this:
