App.js Interpretation of Entrance procedureAt the time of this posting, the Bitcoin price ￥2873.95/$443.95. Why is a crypto currency designed so popular? Why did Microsoft, IBM and other giants enter? Why would a technician who tries to understand Bitcoin be deeply attracted? What's so tempting about it? "Nodejs development Crypto currency", let's explore the password behind it.The Nodejs development

This article explains a very simple cryptocurrency, the goofy currency, before the advent of Bitcoin. It aims to understand the operation mechanism of Bitcoin gradually. The regular goofy coin (goofycoin), the creator is goofy. Is the simplest crypto currency known at the moment. There are only two rules: (1) Goofy can create a new currency at any time, and the newly created coin belongs to him; (2) The person who owns the currency can transfer it to

This article mainly introduces common methods of CRYPTO in the NODE. JS encryption module. For more information, see 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 h

Crypto++ is a set of open source libraries on the application of cryptography, which provides many useful algorithms such as hashing (MD5, SHA), Data encryption (DES, AES), digital signature (RSA, Elliptic curve Signature Algorithm ECDSA), and the algorithm security has been through FIPS 140-2 (http:/ /csrc.nist.gov/cryptval/140-2.htm) validation. crypto++ Library contains a large number of algorithms 1, gr

In the follow-up development of billions of books, it will also use a lot of good experience in functional programming, good practices, further compression of code, improve robustness and maintainability.All things too much,

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's crypto module public key encryption and decryptionNodejs has the following 4 classes related to public key cryptography.1. Cipher: Used for encrypting data;2. Decipher: Used to decrypt data;3. Sign: Used to generate signatures;4. Verify: Used to verify the signature;When using public key cryptography, public and private keys are used to create encrypted data that only the owner of the private key can read, and to authenticate the signature of

is often used to verify that the message is intact and not tampered with.The digest operation is irreversible. In other words, the input is fixed and produces a fixed output. However, if the output is known, the input cannot be rolled back.The pseudo code is as follows. Digest = Hash (message) The common summary algorithm and the corresponding output bits are as follows: md5:128 bit sha-1:160 bit sha256:256 bit sha512:512 bit Examples in Nodejs:var

After the certificate with the X.509 structure is revoked, the serial number will appear in the Certificate Revocation List (CRL). We can save it as one. CRL file, you can view the information of the revoked certificate,. net Framework does not provide classes that can access the attributes of CRL (x509crl is provided in Java). To implement such a function, we need to use. net Framework: Bouncy castle crypto or mono SDK. First, we will introduce how
