generate sha1 key

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

Detailed description using the HMAC-SHA1 signature method. Encryption Algorithm: Copy the code using the HMAC-SHA1 signature method: *** @ brief use the HMAC-SHA1 algorithm to generate the oauth_signature signature Value *** @ param $ key * @ param $

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

First, write in frontNow more and more API interface requirements are required to provide our project SHA1 value, the development version is currently not high, but the release is required. And the current positioning in the major app is also more
