Title: Coins based on md5 hashing algo ?
Post by: johny1976 on August 16, 2013, 02:59:38 PM
Why is no coin using md5 algo? It's a standard for PHP apps (I'm PHP developer, and all PHP developers ae using md5 for password hashing), is it less safe or what?

Hmm..  md5  has been broken.  It has been the advice since at least the early oughts to not use this in any new development and replace its use in old software asap.   If you are still using md5 except for some very special cases where arguable md4 would be the better choice , you are not doing your homework.  If any devs, php or not, are still using md5 for password hashing they are being  negligent.

Oh, I didn't know that. So what should I use instead ?

Sha256. If you are paranoid then scrypt or bcrypt.

I'm using a scrypt function for all my projects.
