MetaMesh Plugin: Full Hash
A MetaMesh plugin that computes SHA-256 hash of the entire file for content identification.
Description
This plugin computes a full SHA-256 hash of files for content-addressable identification. Unlike the quick CID hash used for file tracking, this provides a complete content hash suitable for:
- Content deduplication
- File integrity verification
- Cross-system file matching
Note: This runs on the background queue as hashing large files is I/O intensive.
