crypto Cipher/Decipher validation issues

This also affects Decipher methods.

Here's an example:

const { createCipheriv, randomBytes } = require('crypto');

const cipher = createCipheriv('aes-256-cbc', randomBytes(32), randomBytes(16));

cipher.update('test', 'utf-8', 'bad');

Gives an internal assertion:

Error [ERR_INTERNAL_ASSERTION]: Cannot change encoding
This is caused by either a bug in Node.js or incorrect usage of Node.js internals.
Please open an issue with this stack trace at https://github.com/nodejs/node/issues

final has the same issue:

const { createCipheriv, randomBytes } = require('crypto');

const cipher = createCipheriv('aes-256-cbc', randomBytes(32), randomBytes(16));

cipher.update('test', 'utf-8', 'utf-8');
cipher.final('bad');

Other issue:

const { createCipheriv, randomBytes } = require('crypto');

const cipher = createCipheriv('aes-256-cbc', randomBytes(32), randomBytes(16));

let result = cipher.update('test', 'bad', 'hex');
result += cipher.final('hex');
console.log(result);

Gives no error at all for the wrong input encoding.

Compara el manejo de las codificaciones de entrada y salida no válidas en update y final. Se considera terminado cuando las codificaciones no válidas reciben errores de validación adecuados en lugar de una aserción interna o una aceptación silenciosa.
