About MD5 Generator


A typical application of MD5 is to generate a message digest (Message-Digest) for a piece of information (Message) to prevent tampering. For example, under Unix, there are a lot of softwares that have the same file name and file extension .md5 when downloading. There is usually only one line of text in this file. The approximate structure is as follows:

MD5 (tanajiya.tar.gz) = 38b8c2c1093dd0fec383a9d9ac940515

This is the digital signature of the tanajiya.tar.gz file. MD5 treats the entire file as a large text message, and through its irreversible string transformation algorithm, produces this unique MD5 message digest.

A typical application of MD5 is to generate a fingerprint for a segment of Message to prevent it from being "tampered." For example, you write a paragraph in a file called readme.txt, and generate a MD5 value for this readme.txt and record it, then you can propagate this file to others, if others modify the file Anything you find when you recalculate MD5 on this file (the two MD5 values are not the same).

MD5 is also widely used in operating system login authentication, such as Unix, various BSD system login passwords, digital signatures and many other aspects. For example, in a Unix system, the user's password is stored in the file system by hashing with MD5 (or other similar algorithm). When the user logs in, the system performs the MD5 Hash operation on the password entered by the user, and then compares it with the MD5 value stored in the file system to determine whether the entered password is correct. Through such a procedure, the system can determine the legitimacy of the user's login system without knowing the plain code of the user's password. This prevents the user's password from being known to users with system administrator privileges.

Using this md5 generator is very simple, you only need to enter your string, click the Generate button to generate it, and we have added a new feature, you can hash multiple times for a string. Click on the hash text and the hash will be automatically selected. It is convenient for you to copy and save.
