How does Firebase Auth compute the stored password hash?

User password is fed through crypto_scrypt (https://github.com/firebase/scrypt/blob/master/lib/crypto/crypto_scrypt.c) with the following parameters to generate a 512-bit key:

parameter	value
password	bytes from user password
passwordlen	length of user password in bytes
salt	80 bit salt from a pseudo-random number generator as specified in section 10.1.2 of the NIST SP 800-90 standard + 8-bit separator
saltlen	11
N	16384
