ObjectiveOpen interface in order to avoid being called by others, wasting server resources, which involves signing (Signature) encryptionThe API uses the signature method (Signature) to authenticate the interface (authentication). Each request needs
Nodejs Crypto module MD5 and HMAC encryptionIn 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
Test results and Baidu Encyclopedia test examples are consistent.
The implementation of the need to note: The last four variables a B C D link to the results, attention to the order of the variable high and low, specific reference to Linkresult ()
At present, it can be realized: MD5 algorithm, SHA256 algorithm, first MD5 SHA256, SHA256 after MD5, two MD5, two times SHA256, 8-bit MD5 algorithm after the first 8-bit SHA256, 8-bit SHA256 algorithm after the former 8-bit MD5 algorithm, Password
Currently, the MD5 password database has a huge amount of data, and most common passwords can reverse query the plaintext of the password through the MD5 Digest. To prevent internal personnel (persons who can access database or database backup files)

MD5 encryption and md5 decryption
MD5 Encryption Method
MD5 is a secure hashing algorithm. Two different input plain texts do not obtain the same output value. Based on the output value, the original plain text cannot be obtained, that is, the
MD5, the English meaning is the message Digest, namely the Information Digest, is the commonly used information digest algorithm.It is an irreversible algorithm, that is, if a message MD5 digest into a string of code, you will not be able to restore
