how to use sha1 in php

MD5 and sha1 are one-way encryption Algorithm It is often used for password verification and other scenarios requiring encryption operations. In general, developers can write related functions themselves or use their own functions through Delphi or

Instance Computes the SHA-1 hash of the string "Hello": Definition and usage The SHA1 () function computes the SHA-1 hash of the string. The SHA1 () function uses the United States Secure Hash algorithm 1. Explanation from RFC 3174-the US Secure

Today in docking other people's system, found a very pit problem, SHA1 encryption problem Others system SHA1 encryption is written in PHP, we are C #. The same is true for string 123456 encryption, C # 's SHA1 encrypted string is

I have been studying base64 and sha1 in Delphi today, using units in cnvcl of http://www.cnpack.org, cnsha1.pas and cnbase64.pas. I am very grateful for the contributions of the cnpack group, we can easily use base64 and sha1 encryption in Delphi,

Use PHP for HMAC-SHA1 signing and Authorization header authentication Deom$app _id= ' id ';$host= "Test.abc.com";$port= "80";$app _key= "Key";$app _timestamp= Time();$app _nonce= "8FINTYTUSKBSZGFL". Time().Rand(10,1000);$uri= "/account/ass/verify.do"

Because of different languages, the rules for encryption are slightly different. Then this problem in the Niang can not search a correct answer, hereby record. 1. First, the two basic algorithms need to be consistent, here are the basic rules of SHA1

Why is it wrong to judge whether the sha1 encrypted string after the POST is equal. For example, the encrypted string 356a192b7913b04c54574d18c28d46e6395428ab is returned in the form post. Then, if ($ _ POST ['s '] = '356a192b7913b04c54574d18c28d46e6

For example, my form post came up SHA1 (' 1 ') this encrypted string 356a192b7913b04c54574d18c28d46e6395428ab. Then I if ($_post[' s ']== ' 356a192b7913b04c54574d18c28d46e6395428ab ') Why is it judged false? echo $_post[' s '] is also 356a192b7913b04

Originally intended to write their own, but see the complexity of the algorithm described on the shrink. Forget it, there are ready-made COM object calls, why to care about the algorithm, directly to use on the line. If the following example code
