feat: use allocUnsafe to allocate hash digests

[wemeetagain]

Motivation

• allocation is typically slow, using allocUnsafe to allocate hash digests can help

Description

• use allocUnsafe where possible to allocate hash digests
• use subarray to avoid an additional data copy when using digest with long inputs.
