KunChangLee / PySyft
A library for encrypted, privacy preserving machine learning
KunChangLee/PySyft holds a health index of 28 out of 100, placing it in the At Risk band. It scores highest on Engineering Quality (71/100) and lowest on Security (6/100). It was last updated 2265 days ago. 3 contributors account for most of its recent work.
Software health index
Metrics are grouped into weighted categories on one standardized 1–100 scale. Overall starts as their weighted mean, calibrated against the distribution of the public record so bands carry percentile meaning; when public evidence triggers the High-Risk Jurisdiction Policy, the rating is adjusted and receives an At Risk ceiling of 34.
Score profile
Each axis is a category. The shape matters more than the average — a healthy subject fills the whole shape, while a spike-and-crater profile means strength in one dimension is masking risk in another.
The weighted overall 38 is calibrated to 33 on the published index scale (record calibration 2026-08-02).
Ownership
This repository is owned by a personal account. A single-owner project carries more continuity risk than an organization-backed one.

Metrics by category
Vitality
Is the project alive — is code being written and are releases shipping?
Development activity
Work has arrived and nobody has attended to it
Silence alone is never the finding — a small, finished library may need no commits for years. This alert requires both: no human commit for a long time, and obligations the project is visibly not discharging. Automated commits do not count as maintenance.

An advisory means the version recorded in the dependency graph falls inside an advisory’s affected range. Reachability is not analysed, and the graph includes development and test pins — a finding may concern tooling rather than shipped software.
