This is an introductory article on cryptocurrency, a supplement to the Getting Started Guide section of the Nodejs development crypto currency, mainly for small partners who have not been in touch with Bitcoin or cryptocurrency, and the next content will be related to cryptocurrency.Objective"Cryptocurrency is Money" sounds "idiotic". Think of the meaning behind, the implication is that "cryptocurrency may not be a currency", it is worth pondering. In

The zero-based NODEJS series article will show you how to benefit JavaScript as a server-side script through NODEJS Framework web development. The NODEJS framework is a V8-based engine and is the fastest JavaScript engine available today. The Chrome browser is based on V8, and opening 20-30 pages is a smooth one. The NODEJS Standard Web Development Framework Express helps us quickly build web sites that are more efficient than PHP and have a lower learning curve. Very suitable for small websites

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.

computer will take 1.07x1022 years. In the case of a birthday attack, finding two messages with the same hash value requires 264 messages, and it takes 585 years for a computer to test 1 billion messages per second. Practical application, for example I know ' Password ' MD5 value is 5f4dcc3b5aa765d61d8327deb882cf99, then I use a database to save, as long as I see 5f4dcc3b5aa765d61d8327deb882cf99, I know this is the password ' Password ' uses the value after MD5 processing, the original password
