Use require ('crypto') to call the encryption module. The encryption module requires the underlying system to support OpenSSL. It provides a security credential encapsulation method that can be used for HTTPS security networks and common HTTP connections. This module also provides a set of hash, hmac, cipher, decipher, sign, and verify for OpenSSL) and other methods. Crypto. createCredentials (details) Crea

Use require (' crypto ') to invoke the cryptographic module. The encryption module requires the support of the underlying system to provide OpenSSL. It provides a way to encapsulate security credentials and can be used for HTTPS secure networks and normal HTTP connections. The module also provides a package for OpenSSL hash (hash), HMAC (key hash), cipher (encoding), decipher (decoding), sign (signature), and verify (authentication) methods. Crypto

Nodejs Crypto module MD5 and HMAC encryption In Nodejs, you can use the Crypto module to implement a variety of encryption and decryption processing, in the Crypto module contains similar MD5 or SHA-1 these hashing algorithms, we can implement the HMAC by the Crypto module. What is an HMAC operation? The Chi

This article will explain to you how to useNode.jsthe Crypto module to add salt to your passwordhash. Here, we will not make a detailed comparison of the password storage methods that we do not understand. What we are going to do is to know theNode.jsmechanism of using salt in thehashpassword store. Rest assured, this is the best way to store passwords before other better methods appear. What is this technology? Adding salt is always the t

Encryption techniques are usually grouped into two broad categories: symmetric and asymmetric. Symmetric encryption: Encryption and decryption using the same key, usually called "session key" this encryption technology is widely used today, such as the United States Government adopted DES Encryption standard is a typical "symmetric" encryption method, its session key length of 56bits.non-symmetric encryption: That is, encryption and decryption are not using the same key, usually have two keys

Previous wordsCryptographic modules provide a way to encapsulate security credentials during an HTTP or HTTPS connection. It also provides encapsulation of OpenSSL's hash, HMAC, encryption (cipher), decryption (decipher), signature (sign), and authentication (verify) methods.
