md5

问题 I have raised my concerns in the following thread: how i can get MD5 hash in jdk.7.o? and seen threads like: Cannot use Java 7 installation if Java 8 is installed and I have also studied: https://docs.oracle.com/cd/E74665_01/MOSHP/settings.htm#CIHEFHEF but no use. Since I am using JRE/JDK version > 10, I am unable to obtain MD5 from any keystore of my choice using keytools. It is said that MD5 can be obtained from the keystore, if my JRE version is 7. Also, I have tried and known that when

问题 I have built a new development machine and installed Android SDK. I tried to obtain the Android MD5 debug fingerprint but cannot seem to get it to generate. I have deleted the debug.keystore to create a new one and only the SHA1 fingerprint is present. Please advise Here is my debug.keystore contents: c:>"C:\Program Files\Java\jdk1.7.0\bin\keytool" -list -keystore "C:\users\me\.android\debug.keystore Enter keystore password: ** * ** * * WARNING WARNING WARNING * ** * ** * * The integrity of

问题 I've run into a problem attempting to authenticate from within my web services.

问题 I am looking to use java or groovy to get the md5 checksum of a complete directory. I have to copy directories for source to target, checksum source and target, and after delete source directories. I find this script for files, but how to do the same thing with directories ? import java.security.MessageDigest def generateMD5(final file) { MessageDigest digest = MessageDigest.getInstance("MD5") file.withInputStream(){ is -> byte[] buffer = new byte[8192] int read = 0 while( (read = is.read

问题 This question already has answers here : HEX to Base64 converter for JavaScript (4 answers) Closed 4 years ago . Now I have a string of a MD5 hex digest for a file, and I want to convert it to base64 in order to use the Content-MD5 HTTP header when uploading it. Any help would be appreciated 回答1: var hexArray = myHexString .replace(/\r|\n/g, "") .replace(/([\da-fA-F]{2}) ?/g, "0x$1 ") .replace(/ +$/, "") .split(" "); var byteString = String.fromCharCode.apply(null, hexArray); var base64string

问题 Why is this different? text="tralala" echo -n $text | md5sum - result: def7d827536761c20f449f69262ff20f echo -n "tralala" | md5sum - result : 7e4ef92d1472fa1a2d41b2d3c1d2b77a what am I doing wrong? 回答1: I suspect you mistakenly did not provide the -n (output no newline) flag to echo. See sample from my machine below: $ echo tralala | md5sum def7d827536761c20f449f69262ff20f - $ echo -n tralala | md5sum 7e4ef92d1472fa1a2d41b2d3c1d2b77a - $ text="tralala" $ echo $text | md5sum

问题 I am writing a batch file and I need it to verify a file's MD5 hash before continuing on with the script. For example: @echo off if MD5 equ 79054025255fb1a26e4bc422aef54eb4 ( echo MD5 identical! ) else ( echo MD5 does not match. ) Thanks! 回答1: The standard Windows utility CERTUTIL can be used to generate MD5 (and other) hashes. For example: certutil -hashfile yourFile MD5 However, the output (versions prior to Windows 10) will not be formatted as a single string of contiguous hex digits.

问题 I want to create a MD5 hash code in Qt. My code : QString queryStr; queryStr = QString("%1") .arg(QString(QCryptographicHash::hash(ui->txtPassword->text(),QCryptographicHash::Md5).toHex())); but my code does not work! hash method does not work in Qt ! Any suggestion? 回答1: text() returns QString , QCryptographicHash::hash requires QByteArray and there is no implicit conversion, so you should do this by yourself. Use something like this: QString queryStr; ui->lineEdit_2->setText("hash");

问题 Using the HTML5 File API and any JavaScript crypto library, how can I generate an MD5 hash of the file? To read the file: var reader = new FileReader(); reader.onload = function(e) { var contents = e.target.result; // What goes here? }; reader.readAsBinaryString(data.files[0]); 回答1: This goes there: var reader = new FileReader(); reader.onload = function(e) { var contents = e.target.result; // This goes here: var hash = CryptoJS.MD5(CryptoJS.enc.Latin1.parse(contents)); }; Be sure you include

问题 I'm storing unique user-agents in a MySQL MyISAM table so when I have to look if it exists in the table, I check the md5 hash that is stored next to the TEXT field. User-Agents { id - INT user-agent - TEXT hash - VARCHAR(32) // md5 } There is any way to do the same but using a 32-bit integer and not a text hash? Maybe the md5 in raw format will be faster? That will requiere a binary search. [EDIT] MySQL don't handle hash searches for complete case-sensitive strings? 回答1: Let MySQL do the hard
