What is with the so-called MD5 class?
Also referred to as the MD5 (Message-Digest algorithm 5), it is widely used as the official Message Digest hashing algorithm. Its Inheritance Hierarchy and access can be found in and through the System.Security.Cryptography..::.MD5CryptoServiceProvider space.
It is most commonly used for application of encrypting and decrypting data, adding and ensuring security and integrity of data, files, formats, access, information, enabled through validating such with hashes and cryptography solutions. Using the ComputeHash methods returns as an array of 16 bytes. Some may have a 32-character, hexadecimal-formatted hash, to ensure interoperability small alterations will have to be made. There are newer hash functions (Secure Hash Algorithms SHA-256 and SHA-512) instead of the MD5 class.
An internet standard for a variety of security applications, like integrity of files, data and information, not collision resistant
Some describe it as a unique check-sum to a specific file or piece of data. Determine if/that no modifications were made to it, monitoring, tracking and ‘testing’, verifying it to a degree for added and improved safety and security. Hashes are one-way solutions and operations that you cannot extract the data from Enables password security and cannot store the password, verifies it by calculating it, comparing it against the stored hash.
Hash algorithms in the .NET Framework – there are six keyed and two non-keyed hashes. To be found in the System.Security.Cryptography namespace, class and is derived from the hash algorithm. Representing the abstract class, from which all implementations of the MD5 hash algorithm inherit.
These types of security type functionality and action, map binary strings of an arbitrary length, to small binary strings of a fixed length.
It is a cryptographic hash. It functions infeasible to find two distinct inputs that hash to the same value. Even the smallest of changes to the data result in large, unpredictable changes in the hash. The hash size for the MD5 algorithm is 128 bits
