功能描述
Add password protection and encryption to a PDF. Supports AES-256, AES-128, RC4-128 encryption and granular permissions.
使用说明 (SKILL.md)
Lock PDF
What It Does
Encrypts a PDF with password protection. Supports AES-256 (default), AES-128, and RC4-128 encryption. Allows setting separate user and owner passwords with granular permission controls.
When to Use
- Protect a PDF with a password before sharing
- Set permissions (allow print but deny copy/modify)
- Re-encrypt an already encrypted PDF with a new password
Required Inputs
password— user password (required to open the PDF)- Plus one of:
url,base64_pdf, or multipartfileupload
Authentication
Send your API key in the CLIENT-API-KEY header.
Get your free API key at https://pdfapihub.com. Full API documentation is available at https://pdfapihub.com/docs.
Use Cases
- Confidential Document Protection — Encrypt contracts, NDAs, or financial reports before sharing
- Read-Only Distribution — Allow viewing and printing but prevent copying or editing
- Client Deliverables — Password-protect reports or proposals sent to clients
- Compliance — Encrypt sensitive PDFs (HIPAA, GDPR) before storage or transmission
- Exam Papers — Lock exam PDFs with a password released only at exam time
- IP Protection — Restrict copying from proprietary documents while allowing viewing
Permissions
| Permission | Description |
|---|---|
print |

copy |
Allow copying text |
modify |

Example Usage
curl -X POST https://pdfapihub.com/api/v1/lockPdf \
-H "CLIENT-API-KEY: your_api_key" \
-H "Content-Type: application/json" \
-d '{
"url": "https://pdfapihub.com/sample.pdf",
"password": "viewerPass",
"owner_password": "adminPass",
"permissions": { "print": true, "copy": false, "modify": false },
"output": "url"
}'
安全使用建议
This skill forwards your PDF content and an API key to pdfapihub.com to perform encryption. Before using it, verify the service and its privacy/retention policies (especially if your PDFs contain PHI or other regulated data), confirm TLS and that the CDN/endpoint domains are legitimate, and avoid sending highly sensitive documents until you've validated compliance. Consider local encryption tools if you need to keep documents on-premises. Also ensure you handle and store the CLIENT-API-KEY securely (don't paste it into chatlogs) and test the service with non-sensitive sample documents first. Finally, note the minor metadata inconsistency: the skill expects an API key header at runtime even though the registry metadata shows no platform-stored credential.
功能分析
Type: OpenClaw Skill
Name: lock-pdf
Version: 1.0.0
The skill is a standard API wrapper for the pdfapihub.com service, designed to provide PDF encryption and password protection. All files (SKILL.md, skill.json, and example.json) consistently describe legitimate functionality, and there are no indicators of malicious intent, data exfiltration, or prompt injection.

Purpose & Capability
The skill's name/description (locking/encrypting PDFs) matches the instructions and skill.json which call an external API (pdfapihub.com) and require an API key header. Requiring an API key and accepting url/base64/file inputs is appropriate for this purpose. Minor metadata mismatch: registry-level 'Required env vars' lists none while skill.json declares apiKey auth required; this is explainable (the API key is provided at request time via header rather than as a platform env var) but should be noted.
Instruction Scope
SKILL.md instructs the agent to POST PDF data (url/base64/multipart file) and an API key to pdfapihub.com. There is no instruction to read unrelated local files, secrets, or system config. Important operational note: using the skill will transmit entire PDF contents (possibly sensitive) to a third-party endpoint — the SKILL.md lists HIPAA/GDPR use cases but provides no proof of compliance or retention policy.
Install Mechanism
Instruction-only skill with no install spec and no code files — nothing is written to disk by the skill itself. This is the lowest-risk installation model.
Credentials
The skill requires an API key sent in the CLIENT-API-KEY header (documented in SKILL.md and skill.json). The platform metadata shows no declared primary credential or required env vars; this is not harmful but is a minor inconsistency in how credentials are represented (runtime header vs platform-stored env var). No other credentials or unrelated secrets are requested.
Persistence & Privilege
always is false and the skill does not request persistent or elevated platform privileges. Autonomous invocation is allowed (default) but not combined with other privilege-escalating flags.
