在线MD5散列发生器

i read many answers about converting hex to binary in SO. I tried to implement it with md5:

import hashlibc = hashlib.md5("123hello123".encode('ascii'))print(c.hexdigest())for _hex in c.hexdigest():    _hex = int(_hex, 16)    print(bin(_hex)[2:], end="")

i get the output:

b303fa684382db471658016690101792 1011110111111101011010001001110001011011011100111111010110000111011010010101111100110

where as when i convert in an online converter i get:

10110011000000111111101001101000010000111000001011011000000000000000000000000000000000000000000000000000000000000000000000000000

what is the right answer? how should i correct my program?

I am writing a basic password cracker for the MD5 hashing scheme against a Linux /etc/shadow file. When I use commons.codec's DigestUtils or Crypt libraries, the hash length for them are different (among other things).

When I use the Crypt.crypt(passwordToHash, "$1$Jhe937$") the output is a 22-character string. When I use the DigestUtils.md5[Hex](passwordToHash + "Jhe937")(or the Java MessageDigest class) the output is a 32-character string (after converted). This makes no sense to me.

aside: is there no easy way to convert the DigestUtils.md5(passwordToHash)'s byte[] to a String. I've tried all* the ways and I get all non-valid output: Nz_èJÓ_µù[î¬y

*all being: new String(byte[], "UTF-8") and convert to char then to String

I'm learing Vala and i'm trying to build a Gtk+ Gui wich output an MD5 hash of a file. Currently i'm using valadoc.org to code my application and i'm using GLib.Checksum to calculate the checksum. GLib.Checksum handle MD5, SHA1, SHA256 and SHA512 (Found in the documentation).So i used the code in the documentation in order to calculate the hash of an input file's path. I found that Vala didn't free the GChecksum automatically and i don't how to do it manually.

Thanks for the help.

This is my Vala code:

private string HashSum( string path, string hash){    Checksum checksum = new Checksum (ChecksumType.MD5);    FileStream stream = FileStream.open (path, "rb");    //var stream = File.new_for_path(path).read();   uint8 fbuf[100];   size_t size;   while ((size = stream.read (fbuf)) > 0){      checksum.update (fbuf, size);    }   unowned string digest = checksum.get_string ();   stdout.printf ("%s: %s\n", path, digest);   return @"$hash hash: $digest";}

I used ord to check @ and @‪ are same char. But ord output the same value while md5 does not.

php -aInteractive shellphp > echo ord('@');64php > echo ord('@‪');64php > echo md5('@');518ed29525738cebdac49c49e60ea9d3php > echo md5('@‪');e6124653b6620abe51d7c401a7644674php >

Here is the screenshot,

I'll planed use AES128 with md5 for short messaging (16-64 bytes) with server. I know about MD5 use, it's bad idea, but I think MD5 the best hash solution for iot embedded processors. My messages will be pretty short. Hash will contain decrypted data + some constant "fingerprint" from firmware. I have question about using CBC mode + MD5. When I encrypt first 16 bytes message I got some results from AES and MD5, and then next 16bytes with same input data give me different AES and same MD5. How that fact reduce encryption reliability for AES? Or need use ECB mode?
