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

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

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
