Why md5 hash of a word from a file doesn't match the hash of a string?

问题 I'm trying to create a python program that would read words from a dictionary, create a md5 hash and compare it to a given hash. Everything works fine when I try to compare two hashes of words that haven't been read from a file: if hashlib.md5(b"string").hexdigest() == "b45cffe084dd3d20d928bee85e7b0f21": print("Equal!") But when I read the words line by line from a file, the hash of the word is different. The code looks like this: f = open('short.txt', 'r') stringHash =

Hashset for MD5 Checksum of Files in Google Drive

问题 I here am able to generate the MD5 hash of the files in the Google Drive. The next step is I want to like compare those hashes and should there be an identical hash , the program will prevent the application from uploading that file due to the same hash. I tried declaring a hashset and calling the MD5checksum in the parameters and declaring a function to generate the hash but neither both these are working, public static List<GoogleDriveFiles> GetDriveFiles() { DriveService service =

问题 I know that there are alots of questions about this subject but i really need to ask this. Today I've been working on encrypting passwords with md5. So what I've done is. I got 4 salts. (they changes depending on user values) from email id and substr then md5 them from email and id substr other positions a long string, substr it and then md5 it another long string, substr it and then md5 it Then i md5 salt1 and 3 and the password with salt 2 and salt4 After this I have to change the password

MD5 Hash in C# doesn't match MD5 Hash in Action Script

问题 I'm hashing some data in Action Script then comparing the hash to one computed in C#, but they don't match. Anyone know why? Here's what I do in Action script: var hash : String = MD5.hash(theString); And here's what I do in C#: var md5Hasher = MD5.Create(); byte[] data = md5Hasher.ComputeHash(Encoding.UTF8.GetBytes(theSameString)); var sBuilder = new StringBuilder(); for (int i = 0; i < data.Length; i++) { sBuilder.Append(data[i].ToString("x2")); } var hash = sBuidler.ToString(); I'm

suppressing or not allowing the access time to be modified java

心不动则不痛 提交于 2019-12-11 03:27:47
问题 I'm writing a Java Class which extends Ant Zip Task to do a particular job for me. I want to create a zip file and once that file is created, I want to suppress the access time in the inode so I can't be modified or find a way to not let it change, even if the file is modified. The reason for that is I made a md5 hash which depends on the access time. Thus that's giving me a lot of trouble, and making the access time constant will solve my problem. Does someone now how would I accomplish that

MySQL: UNIQUE text field using additional HASH field

问题 In my MySQL DB I have a table defined like: CREATE TABLE `mytablex_cs` ( `id` mediumint(8) unsigned NOT NULL AUTO_INCREMENT, `tag` varchar(6) COLLATE utf8_bin NOT NULL DEFAULT '', `value` text COLLATE utf8_bin NOT NULL, PRIMARY KEY (`id`), KEY `kt` (`tag`), KEY `kv` (`value`(200)) ) ENGINE=MyISAM AUTO_INCREMENT=7 DEFAULT CHARSET=utf8 COLLATE=utf8_bin I need to implement a UNIQUE constraint (key) on the value field. I know that is not yet possible to define a unique index on the entire value

Best practices for efficiently storing md5 hashes in MongoDB

问题 Assuming we have an md5 hash: With ruby: >Digest::MD5.hexdigest("ZZtop") => "d3e5c7c22df12b70e882f593432a3bdd" Possible field types: :type => String :type => Hash Which should I choose? 回答1: Use a String. A Hash in BSON refers to a key-value pair set. 回答2: In MongoDB, hash does not mean a cryptographic fingerprint (as in MD5 or SHA-1). It means hash as in hash table (a data structure that allows the storage of key-value pairs). You have to use a string to store a MD5 fingerprint. 回答3: String,

How to get File both MD5 and SHA1 checksum at the same time when upload a new file?

问题 I am working on a storage system. Users upload files to the server. On the server side, I want to implement a program to get the checksums of the file using both MD5 and SHA1. I know how to calculate checksums using DigestInputStream functions, but it seems only supports one method (either MD5 or SHA1) a time. How can I calculate both MD5 and SHA1 a the same time when dealing with the upload stream in JAVA? Thanks guys 回答1: Use two MessageDigest instances (one for MD5 and one for SHA1) and

问题 I'm trying to run the md5 source code on my linux machine. I got the code from here: https://tools.ietf.org/html/rfc1321. At the bottom of the link, it claims that the output of the MD5 test suite should be the following: MD5 test suite: MD5 ("") = d41d8cd98f00b204e9800998ecf8427e MD5 ("a") = 0cc175b9c0f1b6a831c399e269772661 MD5 ("abc") = 900150983cd24fb0d6963f7d28e17f72 MD5 ("message digest") = f96b697d7cb7938d525a2f31aaf161d0 MD5 ("abcdefghijklmnopqrstuvwxyz") =

SQL Server : what is best datatype to store MD5 hash?

问题 I need to store in SQL Server a list of items uniquely identified by a hash. In C# I compute my hash as MD5 hash of concatenation of the item ids ( Guid ). Currently, my hash has datatype byte[] in C# , and binary(16) in SQL Server. Here's the DDL : CREATE TABLE [dbo].[ItemSet]( [GUID] [uniqueidentifier] NOT NULL, [HashCode] [binary](16) NOT NULL, [Item1GUID] [uniqueidentifier] NOT NULL, [Item2GUID] [uniqueidentifier] NOT NULL, ... [UtcModified] [datetime] NULL, CONSTRAINT [ItemSet_PK]
