Why are you hasing in the browser?
Also, what hashing algorithm would break with large input?
bcrypt has a maximum password length of 72 bytes.
https://en.wikipedia.org/wiki/Bcrypt#Maximum_password_length
wouldn't you then just break it up into chunks of 72 bytes, hash them individually, and concatenate the hashes? And if that's still too long, split the hash into 72 byte chunks and repeat until it's short enough?
I don't know the specifics behind why the limit is 72 bytes, but that might be slightly tricky. My understanding of bcrypt is that it generates 2^salt different possible hashes for the same password, and when you want to test an input you have to hash the password 2^salt times to see if any match. So computation times would get very big if you're combining hashes
