What is MD5? Overview of MD5
What is MD5?
MD5 or in technology it is also known as MD5 Message-Digest Algorithmis a cryptographic hash function, used to check the integrity of files downloaded by users on the network or copied between storage devices.
Instead of checking and confirming that there are no changes between two data files by comparing the raw data, MD5 will do this by summarizing the values on the two data files, then comparing. to verify the integrity of the files.
However MD5 is also proven to contain some security holes and is not really useful for highly encrypted data files, but can check MD5, check MD5 of the file to verify integrity. of standard encrypted data files.
Use MD5 Checker or MD5 Generator

The free Microsoft File Checksum Integrity Verifier (FCIV) utility allows you to generate MD5 code from all files, not just text files.
The simplest way to get the MD5 code of a sequence of letters, numbers and symbols using the Miracle Salad MD5 Hash Generator tool. Also you can refer to some more software change MD5 of files, Videos such as MD5 Hash Generator, PasswordsGenerator, and OnlineMD5.
When using the same hashing algorithm will return the same results. That is, you can use the same MD5 calculator to get the MD5 code of some specific text, then use another MD5 calculator to get the same result. This is reproducible on MD5 hash-based checksum generators.
Overview of MD5
MD5 is one of three algorithms that Ronald Rivest created. Where MD2 is the first hash function that Ronald Rivest created in 1989, integrated in 8-bit computers. Although still used, MD2 is not applicable to applications requiring high security, moreover MD2 has proven to be vulnerable.
One year later, MD4 was born in 1990 to replace MD2. MD4 was created for 32-bit computers and is rated much faster than MD2, but also has vulnerabilities and weaknesses.
MD5 was released in 1992, and was also developed for 32-bit computers. Although MD5 is not as fast as MD4, it is considered more secure than previously implemented versions of MDx.
Although rated as more secure than MD2 and MD4, MD5 has also been proven to contain security vulnerabilities, users are recommended to use some other hash function such as SHA-1 instead.

According to researchers from Carnegie Mellon University of the Institute of Software Engineering, "software developers, digital certificate providers (CAs), website owners and users should limit the use of using the MD5 algorithm. Previous studies have shown that MD5 is cryptographically fragile and is no longer suitable for use.”
In 2008, MD6 was also proposed to the US National Institute of Standards and Technology as an alternative to SHA-3.
Some more information about MD5 . code
The MD5 code is 128-bits long and is usually represented by a 32-character hexadecimal number.
Example text: "this is a test, text length doesn't matter” when changing to another value will display as: “6c16fcac44da359e1c3d81f19181735b“.
MD5 will check the integrity of files and data, ie users do not need to check and compare raw data to determine the integrity of data.
In addition, some MD5 "decrypters" tools and programs are advertised as decrypting MD5 values, but are actually generating checksums from multiple values, and then allowing users to checksums in the database. your database to check if the data has been changed or lost.
MD5Decrypt and MD5 Decrypter are 2 free online tools that allow users to do this, but they only work with some common words and phrases.
