Yeah - I know. I have specific security requirements. The main is
first preimage attack resistance. Standard hash functions have more
properties, such as strong collision resistance and second preimage
resistance which has high computational cost and I don't need it.

As I know it has to lower first preimage attack resistance. Anybody
knows more about it's security properties?
