revert hash passwords to md5


Recommended Posts

Why would you ever want to hash back to md5 almost every other hashing method is better 



The MD5 message-digest algorithm is a cryptographically broken but still widely used hash function producing a 128-bit hash value. Although MD5 was initially designed to be used as a cryptographic hash function, it has been found to suffer from extensive vulnerabilities. It can still be used as a checksum to verify data integrity, but only against unintentional corruption. It remains suitable for other non-cryptographic purposes, for example for determining the partition for a particular key in a partitioned database, and may be preferred due to lower computational requirements than more recent Secure Hash Algorithms algorithms.[3]

Or a code to check the password matches their current hash password when logging in.

Same advice as above: keep the password hashed. It's the better option and you are not prohibiting that in your question but we need to know more about the platform you are using. Which language? Do you use a framework? How did you hashed the password when you stored it into the database (with a salt step?)
