Detailed Description

The type to store ssdeep digest after parsing.

This structure contains all information in the ssdeep digest in machine-friendly format. You can accelerate comparing fuzzy hashes by storing this type first.

Field Documentation

ffuzzy_digest::block_size

Block size of the ssdeep digest.

Technically, this is the block size of first block of the digest. Block size of the second block is twice as this.

ffuzzy_digest::digest

Digest buffer for both blocks of the digest.

This buffer stores the digest in a compressed form. From the beginning, the buffer is formed like this:

• len1-sized characters of the first block
• len2-sized characters of the second block

Valid blocks in the buffer do not contain sequences of four or more identical characters.
