The hash produced by MD5 is supposed to be unique (it cannot be since 128-bits even if very large is finite), so for instance You can find out more about collisions here.ĭespite being insecure, MD5 is still widely used as a file fingerprint (such as SHA-1) and password storageīy webmasters that are not well informed about security. ![]() In 1996 actual collisions were also found on MD5 which is considered as insecure since Suffered from security breaches (collisions were found very early). MD5 was created in 1991 as a replacement of MD4 algorithm, that, however being a 128-bits algorithm too, This produces a digital fingerprint of the file or text and thus allows to sign it ![]() MD5 (or Message Digest 5), is a cryptographic function that allows you to create a 128-bits (32 characters in hexadecimal since you only needĤ bits to code hexadecimal) "hash" from any input up to 2^64 bits.
