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.
