Bump. Would like to hear opinions on bloom filter.

Would it be possible to slightly modify the spec to allow for only non-scrypt hashing algorithms?

That would involve adding, say, SHA512 as a KDF, and getting rid of the fixed "scrypt.hash" in the encryption/decryption functions.

2 reasons this might be a good idea:
1. Some people trust SHA more than Scrypt
2. Scrypt is hard on embedded devices. SHA isn't.
