[openssl-users] Is SHA hashing algorithm reversable?

[Sugumar]

Hello,

Ya you are correct James.
But my doubt is what is the best method to hash the password securely with
salt.
I mean which method is preferred by openssl, 

HashValue = Hash(password + salt).
HashValue = Hash( Hash(password) + salt). or something else?
HashValue = Hash(password) + Hash(salt).

or this is up to the user decision?
