SCRYPT Token length exception when derived key length not 32 bytes?

[TheRammer]

It appears "hashcat -m 8900" (scrypt) only recognizes hashes with a derived key length of 32.

My shorter key length of 24 causes an exception:

Code:

Hashfile 'my_sample_hashes.txt' on line 2 (SCRYPT...[hash redacted]): Token length exception

The two hashes in "my_sample_hashes.txt" were created with Perl:

Code:

#!/usr/bin/perl -l
use Crypt::ScryptKDF qw(scrypt_hash);
print scrypt_hash('password1', 'salt', 4096,  8,  1, 32);
print scrypt_hash('password2', 'salt', 4096,  8,  1, 24);

Any suggestions?

Thanks!
