We explore the idea of creating a hash function that produces an $s$-bit digest from a compression function with an $n$-bit output, where $s > n$. % where $s\le 2^{n/2}n$.This is accomplished by truncating a hash function with a digest size of $\ell n$-bits. Our work answers the question of how large $\ell$ can be while creating a digest of $sn$-bits securely. We prove that our construction is secure with respect to preimage resistance and collision resistance for $s \le 2^{n/2}n$.
