Overview

Package mrhash implements the mailru hash, which is a modified SHA1. If file size is less than or equal to the SHA1 block size (20 bytes), its hash is simply its data right-padded with zero bytes. Hash sum of a larger file is computed as a SHA1 sum of the file data bytes concatenated with a decimal representation of the data length.
