Answer 1

Well, you shouldn't encrypt them with MD5 (which is not really secured, most hackers have conversion tables).

Hence, you can hash it with SHA1 (which is usually used).

If you want more security, you can add more salt which is a key you can add like this (just an example, usually used) :

salt+sha1(salt+pass)

This combination can be used with many language.
