key is a raw key used in algorithm. iv is an Initialization vector. key and iv must be 'binary' encoded string (See the Buffers for more information). Note that this happens when using crypto.createCipher or crypto.createCipheriv, with the secret as the initialization vector. The fix is to replace lines 6 and 7 with the following: var step = cipher.update(source) + cipher.final(); var end = decipher.update(step) + decipher.final(); This code works great in previus versionnow i upgrade to Node v8.9.0 on ubuntu 14.04 and i get warnings to not to use crypto.createCipher and to use crypto.createCipheriv so could please some expirienced rewrite above code to use crypto.createCipheriv ? i read Node documnetation and i see that i need to add at the end of crypto From the Node.js docs: Initialization vectors should be unpredictable and unique; ideally, they will be cryptographically random. They do not have to be secret: IVs are typically just added to ciphertext messages unencrypted.

You need to set the authentication tag via decrypt.setAuthTag(), which is currently only available if you use crypto.createCipheriv(algorithm, key, iv) with an initialization vector.

We also use 16 bytes of salt (IV - Initialisation Vector) for the encryption process. Фактический ключ будет получен из этого пароля. Кажется, что вы хотите использовать ключ вместо пароля, поэтому вам нужно использовать crypto.createCipheriv(algorithm, key, iv). The Crypto CreateCipheriv method in node.js In node.js there is the crypto.createCipheriv method than can be used to create an return a cipher object for the purpose of encrypting data. It is typically used as a way to better secure web traffic, but it can also be used as a way to encrypt files on your computer as well. See full list on nodejs.org The implementation of crypto.createCipher () derives keys using the OpenSSL function EVP_BytesToKey with the digest algorithm set to MD5, one iteration, and no salt. The lack of salt allows dictionary attacks as the same password always creates the same key.

As such, the many of the crypto defined classes have methods not typically found on other Node.js classes that implement the stream API (eg update(), final(), or digest()). Oct 31, 2018 · Node.js provides built-in library called ‘crypto’ which you can use to perform cryptographic operations on data. You can do cryptographic operations on strings, buffer, and streams. In this article, we will go through some examples of how you can do these operations in your project. Фактический ключ будет получен из этого пароля.
