# 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.
|
|
|
|

|
| Field | Description |
|
|
|-------|-------------|
