God: Scalable in Memory Data Structure Server in Go

Murmurs main issue (in an attacker controlled context) is how it incorporates the seed in to the hash, not unexpected collisions on non-malicious data.

Further, _any_ hash, even cryptographic, will not protect you if it is not used with a random seed unknown & unpredictable to the attacker.

You have a practical way to generate collisions in, say, SHA-256?

You only need to generate collisions for the keyspace used. Brute forcing 20-30 bit collisions in any hash function is trivial.
