-"""Modular Crypt Format support for scrypt
-
-Compatible with libscrypt scrypt_mcf_check also supports the $7$ format.
-
-libscrypt format:
-$s1$NNrrpp$salt$hash
-NN   - hex encoded N log2 (two hex digits)
-rr   - hex encoded r in 1-255
-pp   - hex encoded p in 1-255
-salt - base64 encoded salt 1-16 bytes decoded
-hash - base64 encoded 64-byte scrypt hash
-
-$7$ format:
-$7$Nrrrrrpppppsalt$hash
-N     - crypt base64 N log2
-rrrrr - crypt base64 r (little-endian 30 bits)
-ppppp - crypt base64 p (little-endian 30 bits)
-salt  - raw salt (0-43 bytes that should be limited to crypt base64)
-hash  - crypt base64 encoded 32-byte scrypt hash (43 bytes)
-
-(crypt base64 is base64 with the alphabet: ./0-9A-Za-z)
-
-When reading, we are more lax, allowing salts and hashes to be longer and
-incorrectly encoded, since the worst that can happen is that the password does
-not verify.
