Hello list. What is the best key stretching method that can be used?
Best for what?
If you are trying to stretch from a password to a key and wish to add some
resistance to password cracking then currently your “mainstream” choices are
scrypt, PBKDF2, and bcrypt. None of those are perfect, but each will do. PBKDF2
is the best established, but it is also the most quirky. If you want to play at
the bleeding edge of this, you can look what has been proposed as part of the
Password Hashing Competition.

If you don’t need a “slow” hash, then perhaps something like HKDF is right for
your particular needs.

But without having a better sense of what you are trying to achieve, nobody can
be confident that they are recommending the right thing to you.

That link actually helped me. Thanks.
