md5

问题 This question already has answers here : Is it possible to decrypt MD5 hashes? (24 answers) Closed 2 years ago . I have password stored in database and its showing on browser as md5 because its saved there as md5 below is the code am using $result=$link->query("select * from adminpanel"); echo "<tr><th>User Name</th><th>Password</th></tr>"; // loop through results of database query, displaying them in the table while($row =mysqli_fetch_array($result,MYSQLI_ASSOC)) { // foreach( $result as

问题 I've got a problem where the MD5 string that my method returns has all uppercase letters. Is there a way other than using [string lowerCaseString] to make the output of the method return a lowercase string? The above method seems hackish to me. Here is the method that I'm using: - (NSString *)MD5String { const char *cstr = [self UTF8String]; unsigned char result[16]; CC_MD5(cstr, strlen(cstr), result); return [NSString stringWithFormat: @"%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X

问题 I'm comparing the performance of two MD5 libraries. When I send them both a string, they return the same hash: Hashing data with 'md5' library... Hash: d8b1e68f2f36743cdf302ed36f9347dc Duration: 0.003s Hashing data with 'create-hash' library... Hash: d8b1e68f2f36743cdf302ed36f9347dc Duration: 0.003s However, when I send them the same UInt8Array, they give me different hashes: Hashing data with 'md5' library... Hash: 77fcf76d3f8c6a0f685f784d7ca6c642 Duration: 0.001s Hashing data with 'create

问题 I want to check that my program is not modified (cracked). So I want program to calculate md5 from self exe and compare. if(GetMD5FromSelf() != "hash") Application.Exit(); //modified so exit But when I put hash to string then the md5 of file will get changed. Is there any way to do this? 回答1: These are some ways you could do it, Option 1 You could store the hash online, This is probably safer because if someone is going to change your program they can also change the hash. Option 2 You could

问题 I am comparing two strings, one String I receive from a server with 32 characters with another one I calculate with the following code: string getMd5(string fileName) { using (var md5 = MD5.Create()) { using (var stream = File.OpenRead(fileName)) { return BitConverter.ToString(md5.ComputeHash(stream)).Replace("-", "‌​").ToLower(); } } } The problem is, that even when the two strings seems identical, the comparison fails because the string returned by the function above contains more

问题 I have a solution in MS VS 2010 that compiles and builds properly after a rebuild all (1). However, after I make a change to a source file and begin debugging, VS recognizes the project is out of date and builds the project (2) successfully (as expected). The problem is that it seems VS begins debugging the project using obj/pdb/etc.. from (1) above instead of (2). If I break into the debugger and navigate to the module that changed in the file of interest, I'm told "the source file is

问题 It is known that 1. if ( md5(a) == md5(b) ) 2. then ( md5(a.z) == md5(b.z) ) 3. but ( md5(z.a) != md5(z.b) ) where the dots concatenate the strings. EDIT --- Here you can find a and b : http://www.mscs.dal.ca/~selinger/md5collision/ Check these links: hexpaste.com/qzNCBRYb/1 - this is a.md5(a)."kutykurutty" hexpaste.com/mSXMl13A/1 - this is b.md5(b)."kutykurutty" They share the same md5 hash, yet they are different. But you can call these strings a' and b' , because they have the same md5. --

问题 I am by no means a security expert or even a novice. I'm a newbie at security at best. Someone suggested I use SHA1 instead of MD5 - why would I choose one over the other? Is one more secure? 回答1: I would use SHA2(256) at the minimum - however: There is little or no point in simply hashing a password in a database due to rainbow table attacks. Equally, salted hashing is better, but if someone has access to your database, then the chances are that they have access to your code in which case

问题 Any one knows why BSD md5 program produces hash output in this format ... MD5 (checksum.md5) = 9eb7a54d24dbf6a2eb9f7ce7a1853cd0 ... while GNU md5sum produces much more sensible format like this? 9eb7a54d24dbf6a2eb9f7ce7a1853cd0 checksum.md5 As far as I can tell, the md5sum format is much easier to parse and makes more sense. How do you do md5sum -check with md5? And what do the -p, -q, -r, -t, -x options mean? man md5 says nothing about those options! :| 回答1: Historical reasons, i guess.
