What is an MD5 hash?
An MD5 hash is a cryptographic hashing algorithm that creates a 128-bit fixed-length string of characters which serves as a digital fingerprint to represent an input string of any length. This allows the user to verify the authenticity of files, such as program executables or downloaded files, by checking if the calculated hashes match and confirming that the file has not been tampered with.
When to use MD5 hash?
MD5 is a commonly used cryptographic hash algorithm and is widely used for file verification and identification. Highly sensitive information such as passwords should not be stored using MD5, however, it can be used to check the integrity of large files, as it is both fast and hard to break. One use-case for which MD5 could be ideal is checking that digital photographs haven’t been tampered with.
The algorithm calculates the data checksums in such a way that any distortion or alteration will show up if compared against the original, making it an effective means of authentication. Additionally, users who need to navigate large numbers of files will find MD5 as an efficient means of indexing; by comparing checksums users can quickly determine which files are alike even if they have different names and extensions.
