What is the Uses of MD5 Algorithm?

There are various uses of MD5 Algorithm are as follows −

  • MD5 stands for Message-Digest algorithm 5. It is a broadly used cryptographic hash function with a 128-bit hash value. As an Internet standard (RFC 1321), MD5 has been used in a broad method of security applications, and is also generally used to test the integrity of files. An MD5 hash is generally defined as a 32 digit hexadecimal number.

  • MD5 was invented by Ron Rivest in 1991 to restore an earlier hash function MD4. The algorithm creates an input a message of arbitrary length and make as output a 128-bit fingerprint or message digest of the input.

  • It is granted that is computationally impossible to generate two messages having the similar message digest, or to create some message having a given pre-defined target message digest.

  • The MD5 Algorithm is designed for digital signature application, where a high file should be compressed in a safe manner before being encrypted with a private key under a public key cryptosystem including RSA.

  • The MD5 Algorithm designed to be rapid on 32-bit devices. Moreover, the MD5 algorithm does not needed any high substitution tables and the algorithm can be coded quite compactly.

  • The MD5 Algorithm is an enlargement of the MD4 message digest algorithm. MD5 is somewhat slower than MD4, but is more traditional in design.

  • It can be used for the goals of data verification in transmission protocols

  • In several web applications, MD5 hash can be used to avoid security breaches, hacking etc. by the method of improving security.

  • MD5 algorithm was produced generally for the objective of security as it takes any message and provides 128bit hash value as output.

  • MD5 was invented to store one way hash of a password, and several file servers also support pre-calculated MD5 checksum of a file so that the user can compare the checksum of the downloaded file to it. Some UNIX based Operating Systems such as MD5 checksum service in their distribution packages.

  • MD5 is basically used to authenticate files. It is much simpler to need the MD5 hash to control a copy of a document against an original than to check bit by bit to view if the two copies match.

  • MD5 was used for information security and encryption, but these days its basic requirement is authentication. Because a hacker can make a file that has the exact similar hash as an entirely multiple file, MD5 is not safe in the activity that someone tampers with a file.

  • MD5 creates a hash value in a hexadecimal format. This competes with multiple designs where hash functions take in a specific element of data, and change it to support a key or value that can be used instead of the original value.
