Consider using `secure_string` crate (or similar) for `Password`

[m4tx]

To avoid having plain-text passwords swapped to disk or read after dropping, we might consider using secure_string crate or something similar.

Perhaps we could consider the same thing for SecretKey.

Thinking of picking up this one, is there anything else I need to know?

@eibrahim95 I think this one is pretty much fully described in the issue description—this is just about making things slightly more secure. Let me know if you need any help!

Do you want me to assign the issue to you?

Thanks @m4tx .
Yes, please assign it to me.
