Quick answer
Your evidence page is the proof record behind your certificate.
The integrity hash is a SHA-256 fingerprint that makes post-issue tampering detectable.
What the evidence page shows
Every SkillLift Labs certificate has a companion page at /verify/[credentialId]/evidence.
Included records
- Quiz scores: passed quizzes with date and score
- Project completions: evaluated module projects
- Peer-review data: where applicable
- Capstone evidence: for Capstone-tier certificates
- Score breakdown: how final score components were derived
This lets employers validate how you earned a credential, not just that you earned it.
Integrity hash (SHA-256)
The integrity hash is generated when your certificate is issued and stored with the record.
Why it matters
If any evidence field is altered later, the computed hash no longer matches.
That mismatch signals tampering immediately.
What the hash covers
The canonical payload includes fields such as:
- holder name
- credential ID
- course name
- tier
- issue date
- score components
Changing any of these values produces a different 64-character hash.
Verify the hash independently
- Open your evidence page and expand Integrity Hash.
- Copy the hash value.
- Hash the canonical payload with a SHA-256 tool (for example
openssl dgst -sha256). - Confirm the computed value exactly matches the displayed hash.
Visibility and privacy
Evidence pages are public for verification purposes.
Anyone with the credential link can view them without login.
If you only want to share certificate summary, share /verify/[credentialId] instead of the evidence URL.
