Uses the crypt() function to do password encryption. This function handles
several schemes such as: MD5, Blowfish, SHA1, SHA2.
SHA-512 is used in Authelia for best security.
The algorithm is fully described in
https://www.akkadia.org/drepper/SHA-crypt.txt
The 'crypt3' npm package has been added as a dependency to use the crypt()
function. The package needs to be compiled in order to call the c function,
that's why python, make and C++ compiler are installed temporarily in the
Docker image.
One can now plug its own SMTP server to send notifications
for identity validation and password reset requests.
Filesystem has been removed from the template configuration file
since even tests now use mail catcher (the fake webmail) to
retrieve the email and the confirmation link.
