About MD5

MD5 (Message Digest 5) is a widely used cryptographic hash function that produces a 128-bit hash value. It was designed by Ronald Rivest in 1991 as an improvement over MD4. Although MD5 was once considered secure, it has since been found to have significant vulnerabilities, including the ability to generate collision attacks, making it unsuitable for cryptographic purposes.

På trods af dets sikkerhedsfejl bruges MD5 stadig i ingenn-Secure-programmer som f.eks. kontrol af filintegritet, fejlkontrolsystemer og ældre systemer, hvor kompatibilitet er påkrævet. Det er vigtigt at bemærke, at MD5 ikke bør bruges til applikationer, der kræver stærk sikkerhed, såsom adgangskodehashing eller digitale signaturer.
