crypt(3) interface to scrypt

[Solar Designer <solar@openwall.com>]

Colin,

As far as I understand, scrypt-1.1.6 is a file encryption program only,
however one of the primary uses for the scrypt key derivation function
is to hash operating system and website users' passwords.

Does a crypt(3) interface to scrypt exist?  Do you have a proposed
encoding to use for the "setting" string (consisting of a hash type
identifier, a salt, and parameters)?

Or do you consider scrypt not mature enough, with incompatible changes
pending?

Thanks,

Alexander
