This implementation takes a passphrase and a salt (and optionally an
|
||||
iteration count, a digest module, and a MAC module) and provides a
|
||||
file-like object from which an arbitrarily-sized key can be read.
|
||||
|
||||
If the passphrase and/or salt are unicode objects, they are encoded as
|
||||
UTF-8 before they are processed.
|

||||
The idea behind PBKDF2 is to derive a cryptographic key from a
|
||||
passphrase and a salt.
|
||||
|
||||
PBKDF2 may also be used as a strong salted password hash. The
|
||||
'crypt' function is provided for that purpose.
|
||||
|
||||
Remember: Keys generated using PBKDF2 are only as strong as the
|

passphrases they are derived from.
