md5

问题 Recently I have used same code on PHP and it's working fine but when I tried Node Js, it's not working for me. Please check once: PHP $signature = $ACCID . "POST" . strtolower(urlencode($url)).$requestContentBase64String; $hmacsignature = base64_encode(hash_hmac("sha256", $signature, base64_decode($APIKey), true)); NODE CODE : var signature = ACCID+"POST"+encodeURI(url).toLowerCase()+requestContentBase64String; var hmacsignature = base64.encode(crypto.createHmac('sha256', APIKey).update

问题 I've been in discussion with this security guy. He's probably the most I can afford for my new project. Anyways, it is a service that saves sensitive data (Password, PINs) that can be requested by the user via phone. The user has a password (4 digits) which he uses to access the sensitive data. The security guy told me he would use MD5 to hash the password that is used to access the sensitive data. Here the discussion started, as I thought, and am quite sure, that MD5 is too vulnerable since

问题 for some reasons I can't use MessageDigest.getInstance("MD5") , so I must write the algorithm code in manual way, my project is scan duplicate document (*.doc, *.txt, *.pdf) on Android device. My question is, what must I write before entering the algorithm, to scan the duplicate document on MY ROOT directory on Android device? Without select the directory, when I press button scan, the process begin, the listview show. Is anyone can help me? My project deadline will come. Thank you so much.

问题 Are there algorithms for putting a digest into the file being digested? In otherwords, are there algorithms or libraries, or is it even possible to have a hash/digest of a file contained in the file being hashed/digested. This would be handy for obvious reasons, such as built in digests of ISOs. I've tried googling things like "MD5 injection" and "digest in a file of a file." No luck (probably for good reason.) Not sure if it is even mathematically possible. Seems you'd be able to roll

问题 Just now I'm working in a financial project. Here, the team is thinking to use MD5 for password hashing . But, today is easy copy a SHA1 or MD5 password to decrypt, inclusive if they are complex password like: My$uper$ecur3PAS$word+448 , you might use a online page to decrypt it and there is it. Small and mid-range developers (including me) uses those hashing methods , but I think is not enough to provide security over the database. (Excluding firewalls , network security , iptables , etc.).

问题 I have problem with importing md5 library I just use the code below: import md5 filemd5 = md5.new(password.strip()).hexdigest() I also have tried this code : from hashlib import md5 filemd5 = md5.new(password.strip()).hexdigest() also this code : from md5 import md5 But none of them are working ! when I run the code,it gives me this error: 11.py", line 1, in <module> import md5 ImportError: No module named 'md5' What Should I Do ? Am I Importing The Wrong Library ? 回答1: md5 is not a module,

问题 Hi I have some strings generated using the following code: private static string CalcHashCode(byte[] data) { MD5CryptoServiceProvider md5Provider = new MD5CryptoServiceProvider(); Byte[] hash = md5Provider.ComputeHash(data); return Convert.ToBase64String(hash); } How can I get a unique long from a encoded base64 string, I mean, the opposite operation, and then convert it to long? private long CalcLongFromHashCode(string base64Hashcode) { //TODO } Thanks in advance. 回答1: You can't convert a

问题 I have a form in which I am taking username and password from user, and I am converting the password to md5. Then I insert it into database. In user login form, I take the password and convert it to md5. Then I compare both passwords. It matches in some condition but fails if password = p@$$w0rd . What is the issue ? And what is the solution for this issue? From my form to database password of p@$$w0rd to md5 is b7463760284fd06773ac2a48e29b0acf and from login form it is

问题 I am converting PHP code to Node JS. I am facing a issue with MD5 binary raw that is MD5('String',true) and getting �S���<]zVC..zv�� . I have tried in Node js but i am not getting same string on Node js. Please check my code. var md5 = require('md5'); var requestArray = [{ "fname": "mobilenumber", "fvalue": '1234568970' }, { "fname": "phone", "fvalue": '000000000' }]; var post_data = JSON.stringify(requestArray); var m = md5(post_data); I have tried to pass true parameter but it's

问题 I have the following code in C u_char buf[64] = "hahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahaha"; //Make MD5 hash over buffer MD5_Init(&ctx); MD5_Update(&ctx, buf, sizeof(buf)); MD5_Final(buf, &ctx); MD5_Init , MD5_Update and MD5_Final are from openssl library. The above code make a MD5 hash over the buffer buf . I want to make the same thing with linux command using md5sum $echo -n "hahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahaha" | md5sum but I did not get
