Problem with scrypt

[kost]

I have a hash I believe is scrypt however I'm not 100%, the hash originally wasnt base64 encoded nor did it have SCRYPT: at the start, I base64 encoded the salt and digest but I'm getting line length exception with and without base64 encoding..

example hash(not real)

Code:

SCRYPT:4096:12:4:XVd2LXBjaFllI1kwMSptWQ==:ZWViZjZjNTLxOTZjMDNYMGFhNGQwMDYxMpc5OTA2OWQ2MmM5NzgxYTJmMDc6ZTYwMDY5MTOjYjkxNjNjOTM5Mw==
