阅读更多关于 MD5 Hash From String

问题 Need to get MD5 hash from string. Get an error MD5 is null. I am tying to get a 32 character MD5 hash from a string. using (System.Security.Cryptography.MD5 md5 = System.Security.Cryptography.MD5.Create("TextToHash")) { byte[] retVal = md5.Hash; StringBuilder sb = new StringBuilder(); for (int i = 0; i < retVal.Length; i++) { sb.Append(retVal[i].ToString("x2")); } } 回答1: Need to get MD5 hash from string. Then first you need to convert your string to binary data in some form. How you do that

Ant: Rename files to include their MD5

阅读更多关于 Ant: Rename files to include their MD5

The question is likely VERY trivial for anyone familiar with ant, of which I only use the basics thus far. I know how to rename files, e.g. I already use: <copy todir="build/css/"> <fileset dir="css/"> <include name="*.css"/> </fileset> <globmapper from="*.css" to="*-min.css"/> </copy> I know how to calculate an MD5: <checksum file="foo.bar" property="foobarMD5"/> I don't know how to include the second into the first , to rename all those files to include their MD5 - the purpose is to serve as webbrowser cache buster. The other cache-busting option, to append "?[something]" is not as good, as

Google Drive MD5 checksum for files

阅读更多关于 Google Drive MD5 checksum for files

问题 I'm not a programmer, just a regular user of Google Drive. I want to see if the files are uploaded correctly. I go through a whole process in the OAuth 2.0 Playground that lists all files, shows the MD5 checksums but also lots of information per file. If I upload a new file it's hard to search for it and verify its md5 checksum. Is there an easier way (through an app, maybe?) to show/list MD5 checksums for the uploaded files? I wonder why the Details pane doesn't have it, only lists the file

Hashing a file in Python

问题 I want python to read to the EOF so I can get an appropriate hash, whether it is sha1 or md5. Please help. Here is what I have so far: import hashlib inputFile = raw_input("Enter the name of the file:") openedFile = open(inputFile) readFile = openedFile.read() md5Hash = hashlib.md5(readFile) md5Hashed = md5Hash.hexdigest() sha1Hash = hashlib.sha1(readFile) sha1Hashed = sha1Hash.hexdigest() print "File Name: %s" % inputFile print "MD5: %r" % md5Hashed print "SHA1: %r" % sha1Hashed 回答1: TL;DR

Is this a good way to encrypt passwords with MD5?

阅读更多关于 Is this a good way to encrypt passwords with MD5?

问题 I have never encrypted a password before, and this is what I came up with to do it, with the aid of this article. The article didn't include salt, so I had to figure it out myself: UTF8Encoding encoder = new UTF8Encoding(); byte[] salt = new byte[8]; new Random().NextBytes(salt); byte[] encodedPassword = encoder.GetBytes(txtPassword.Text); byte[] saltedPassword = new byte[8 + encodedPassword.Length]; System.Buffer.BlockCopy(salt, 0, saltedPassword, 0, 8); System.Buffer.BlockCopy

Can I use an already MD5 encoded password in Digest Authentication

阅读更多关于 Can I use an already MD5 encoded password in Digest Authentication

I have MD5 hashes of passwords in a database that I want to use against HTTP AUTH DIGEST. But in reading the docs, it looks like the digest hash contains a hash of the username,realm and plaintext password. Is there any way to use the MD5 hash of the password in this situation? No. If the hash they need is generated like so: MD5(username + realm + password) You are out of luck. If they are hashing the password like so: MD5(MD5(password) + username + realm) You'd be able to do that with just the hashed password. But it doesn't sound like that's what's going on. Remus Rusanu No, you have to

微信小程序------MD5加密（支持中文和不支持中文）和网络请求（get和post）

阅读更多关于微信小程序------MD5加密（支持中文和不支持中文）和网络请求（get和post）

开发中常常遇到MD5加密，最近做小程序也用到了，简单总结了一下；这要有两个加密文件，一个不支持中文，一个支持，所以你选择支持的来用就行了；也随便说说小程序的get和post网络请求。来看看效果图：网络请求代码： requestData: function (appid, token, itype, callback, offset, count){ wx.request({ url: "xxxxxx", method: "POST",//GET data: { m: 'api', appid: appid, token: token, c: itype, a: 'batchget', offset: offset, count: count }, header: { 'Content-Type': 'application/x-www-form-urlencoded', //POST //'content-type': 'application/json' //GET }, success: function (res) { console.log(res.data.data) callback(res.data.data) } }) }, 当然有点前提，微信小程序网络请求需要去微信平台服务器域名配置，当然也可以有第二种方式，勾选不验证域名，

Can I use md5 authentication with psycopg2?

阅读更多关于 Can I use md5 authentication with psycopg2?

After two hours of reading documentation, source code and help-threads, I'm giving up. I can't get psycopg2 to authenticate with a md5-string. According to this thread I don't have to anything besides enabling md5-auth in pg_hba.conf . This is my current pg_hba.conf : # TYPE DATABASE USER CIDR-ADDRESS METHOD local all all md5 host all all 127.0.0.1/32 md5 host all all ::1/128 md5 host all all 0.0.0.0/0 md5 And I use psycopg2 like this: psycopg2.connect(host='localhost', port=5433, user='me', password='md5xxxx').cursor() Which gives: psycopg2.OperationalError: FATAL: password authentication

Is there an MD5 Sum function in PL/SQL

阅读更多关于 Is there an MD5 Sum function in PL/SQL

In Oracle SQL, is there an MD5 function or something available to me? I would like to do something like... select name, md5_sum( name ) from person; René Nyffenegger See this Tahiti Link . Under MD5 Procedures and Functions it says These subprograms generate MD5 hashes of data. The MD5 algorithm ensures data integrity by generating a 128-bit cryptographic message digest value from given data. Also note, that DBMS_OBFUSCATION_TOOLKIT is deprecated and can/should be replaced with DBMS_CRYPTO , see this Tahiti Link You may want to check the DBMS_OBFUSCATION_TOOLKIT.MD5 procedure. Here is an

Why PHP's md5 is different from OpenSSL's md5?

阅读更多关于 Why PHP's md5 is different from OpenSSL's md5?

问题 I am quite confused as to why I am seeing different results for md5 hashing in PHP and in OpenSSL. Here is the code that I am running: php -r "echo md5('abc');" Results in: 900150983cd24fb0d6963f7d28e17f72 While this: echo abc | openssl md5 Results in: 0bee89b07a248e27c83fc3d5951213c1 Why? 回答1: There is only one way to compute MD5. A blind guess is that the second one also includes a newline inside the string being hashed. Yeh, verified it. That's it. 回答2: As everyone noted, the problem is
