Password Encryption: DES, MD5, Blowfish.
Password Encryption: DES, MD5, Blowfish.
What should be considered when choosing Password Encryption format ? Why do some distributions default to Blowfish when according to Linux Install DES is reported as Linux Default ? What effect has the Password Encryption format when using Linux in multi operating systems environment. Let's say Linux, Windows, NetWare and MacOS. What effect has the Password Encryption format when Linux network spans across North America, Europe, Asia and Africa ? How can Password Encryption Format be changed after Linux system is already installed and configured ? Are there other Password Encryption format beside DES, MD5, Blowfish ? |
When is it due?

Please note: md5 passwords used for *nix are salted, I have a feeling you're referencing a MySQL issue or a file integrity issue, both of which are vastly different. If I am wrong, I really would be interested in seeing something about it. |
With MD5, people have found "collisions", i.e. two different files having the same MD5 hash. This is the reason some people are questioning it. As far as I know, noone has been able to start with a fixed (in the sense of mathematics) file A, and produce a different file B having the same MD5 hash.

While I do not place unfailable trust in any method of encryption, I have selected md5 passwords across my network (and other computers I have setup)... if there is a reason to change this, I would be interested in seeing it. I have looked myself after I first read the comment above but been unable to find anything on it. |
