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.

Inizia eseguendo gli esempi di Cipher e Decipher nell’issue ed esamina i percorsi dei metodi crypto Cipher/Decipher che attraversano. Confronta la gestione delle codifiche di input e output non valide in update e final. Il lavoro è completato quando le codifiche non valide ricevono errori di validazione appropriati invece di causare un’asserzione interna o essere accettate silenziosamente.
