Suggestion: Adding link to scrypt docs

[githubUser982]

Suggestion: Since index.md suggests that you should use scrypt instead, perhaps it could link to nodes scrypt docs: https://nodejs.org/api/crypto.html#crypto_crypto_scrypt_password_salt_keylen_options_callback Otherwise new users, that may think everything good is a module, may install node-scrypt which already recommends using crypto.scrypt instead.

I believe the rst markdown would be:

scrypt <https://nodejs.org/api/crypto.html#crypto_crypto_scrypt_password_salt_keylen_options_callback>_

Thank you for your time.

This is a Python module, linking to node docs would not make sense
