md5

问题 This question already has answers here : Is it possible to decrypt MD5 hashes? (24 answers) Closed 3 years ago . I have encoded a string with md5() and I want to decrypt the same string. I have written the following code: <?php $rr = md5(utf8_encode('hello')); echo $rr; $rr1 = md5(utf8_decode('5d41402abc4b2a76b9719d911017c592')); echo '<br/>' .$rr1; ?> Now I am able to encrypt the string. But now, I want to decrypt the string. I have tried: md5(utf_decode('string')); But it is not working.

问题 I'm having a question regarding the uniqueness of md5 function. I know that md5 (with microtime value) are not unique, however, they are pretty unique :) How can I calculate the probability of a collision between two portions of an md5 hashes? For example: The following in php that generates a 8 chars string from md5 result: substr(md5(microtime()), 0, 8); A second scenario - What if the index of it is unique (so it gets a different portion of the hash each time)? substr(md5(microtime()),

问题 when i try to get the md5 of my computer by the command "keytool -list –alias androiddebugkey –keystore d:\debug.keystore" , there comes with the error "keytool error ： java.lang.RuntimeException:error，–alias is not a legal command" 回答1: If u r using eclipse, try using "Keytoool for Eclipse" . Hope it reduces the burden of getting MD5 key. FYI you need to use "keytool -v -list" instead of "keytool -list" if you need all the type keys(MD5 , SHA etc.,). 回答2: did you copy and paste the command?

问题 I am passing id no to Url and get the id from GET function but id no which I passed to URL that not accepting the update query because of MD5. I tried $id=md5($_GET['user']); but still getting issue. My user_id is 1 and that is converting into the md5 number and passing to update function to update the table. Would you help me in this? $User_id1=1; $user_id=md5($User_id1); http://www.domaine.com/process.php?user=$user_id if(isset($_GET['user'])) { $id=$_GET['user']; $sql="UPDATE request SET

问题 I discovered that when I use php md5_file function to get the md5 checksum of the image, the checksum is different everytime. Is it the gif image or is the md5_file() function that is dynamic? 回答1: Unless the file contents change this is impossible md5_file("path/file"); If file stays the same the output will be the same hash every time 来源： https://stackoverflow.com/questions/14055780/php-md5-file-function-with-gif-file

问题 I'm trying to md5 some file with as3corelib , but if I compare the as3 hash with a php one, I get different strings. That's what I do: _loader = new URLLoader(); _loader.load( new URLRequest( "image.jpg" ) ); _loader.addEventListener( Event.COMPLETE, completeHandler ); private function completeHandler( event:Event ):void { var data:ByteArray = new ByteArray(); data.writeUTFBytes( _loader.data ); var hash:MD5Stream = new MD5Stream(); trace(hash.complete(data)); } I've already googled for this

问题 I have a file hashed to a standard md5 Hash Correction: OpenSSL Hashes are HEXDECIMAL representations. MD5 Hash: 57ED2E029BF9CA39383D2A671EF4FB50 I have a program that requires a byte encoding base64 md5 hash. MD5 BASE64 byte: 8se7isyX+S6Yei1Ah9AhsQ== How do you use pythons 'binascii' b2a methods to convert the standard MD5 hash to a Base64? The below is wrong. import binascii bin = binascii.a2b_uu('57ED2E029BF9CA39383D2A671EF4FB50') base = binascii.b2a_base64(bin) Output +>

问题 I'm having this piece of code that computes the MD5 hash for a given input file. public static String ComputeMD5(String filename) { using (var md5 = MD5.Create()) { try { using (var stream = File.OpenRead(filename)) { return BitConverter.ToString(md5.ComputeHash(stream)).Replace("-", "").ToLower(); } } catch (Exception) { // File is not accessible, return String.Empty return String.Empty; } } } I'm running this time consuming operation in a separate thread. For very big files this operation

问题 I am trying to identify files with duplicate contents. Decided to do a comparison using a hashing mechanism (MD5, SHA1 or any other). Works fine with ".txt" files. However, with MS Office files (.doc,.docx,.xls, etc) this fails. MD5/SHA1 hash is not constant for MS Office files, even if they have the same "text" content. I assume MS Office stores some kind of meta-data in the file, which changes each time you save the file. Thus the hash is different. e.g. I have a file ABC.doc and I compute
