(yet another pytest port needing PY_IGNORE_IMPORTMISMATCH=1 to avoid
"imported module .../lib... is not the same as the test file we want to
collect [file without lib...]")
This is a set of Python bindings for the scrypt key derivation function.
Scrypt is useful when encrypting passwords as it is possible to specify a
*minimum* amount of time to use when encrypting and decrypting. If, for
example, a password takes 0.05 seconds to verify, a user won't notice
the slight delay when signing in, but doing a brute force search of
several billion passwords will take a considerable amount of time. This
is in contrast to more traditional hash functions such as MD5 or the SHA
family which can be implemented extremely fast on cheap hardware.
