This paper mainly describes the process of computing the Information digest using the SHA1 algorithm.Security System (0)--encryption and decryption algorithm, message digest, message authentication technology, digital signature and public key

usually, the encryption algorithm used is simple and efficient, the key is short, the encryption and decryption speed is fast, the decoding is extremely difficult. This article describes the use of Md5/sha1,dsa,desede/des,diffie-hellman. The

Recently in the project to use the network Request signature authentication method, so on the internet to find the OC sha1加密 method, quickly found a public use of the package good method, the following code isFirst you need to add a header

Digest algorithm MD5, SHA1 introduction and application instance code in Python, pythonsha1 For algorithm learning, I think most of the algorithms in programming languages are in the same place. The main aspect is to understand what this algorithm

As the SHA1 signature algorithm into the phase of elimination, gradually discarded, SHA1 upgrade to SHA2 is the trend.Microsoft has officially released the SHA1 deprecation strategy: http://blogs.technet.com/b/pki/archive/2013/11/12/sha1-deprecation-

First, let's introduce the concept of MD5 and SHA1.MD5The full name of MD5 is message-digest algorithm 5 (Information-Digest algorithm). 128-bit length. At present, MD5 is an irreversible algorithm.It has high security. It corresponds to any string
