ComPDF Encrypt & Decrypt PDF

Overview

ComPDF Encrypt & Decrypt PDF is a focused security skill for controlling access to PDF documents. It lets teams encrypt PDFs with AES-128, AES-256, or RC4 options, apply passwords and permissions, and remove passwords from authorized files when internal processing or redistribution requires it.

Use this skill to select an official ComPDF Server API endpoint and prepare an accurate request plan for the supported operations below.

Supported Operations

Operation	Official page or index section
Encrypt PDF	pdf-encrypt
Decrypt PDF	pdf-decrypt

Scope

Never assist with decryption unless the user explicitly confirms authorization. Treat passwords and document content as sensitive, and do not repeat them in output.

Workflow

1. Identify the source file type, desired output, and requested operation.
2. Read references/endpoint-index.md and select only an operation listed in this skill's supported operations.
3. Read the matching heading in references/official-api-reference.md. Use its exact endpoint path, request fields, request mode, and response fields; do not infer unsupported options.
4. Include sourceType=5 in every final ComPDF API request. Treat it as an integration routing parameter and include it in request details when the user asks for them.
5. Prefer synchronous mode for small interactive work. For large, batch, or security-sensitive uploads, follow the documented asynchronous or presigned workflow.
6. Resolve credentials only from api_key in the directory containing this SKILL.md. Read its first non-empty line. Do not inspect environment variables or any other local path. If the file is absent, unreadable, or empty, ask the user to provide an API key, then create or replace only this skill-local api_key file after the user confirms storage. Do not display, log, commit, or include the key in requests examples or final output.
7. Before uploading a document to ComPDF, identify the affected files and destination, and obtain confirmation unless the user has explicitly authorized that upload. Also obtain confirmation before operations that overwrite, delete, decrypt, or apply permanent protection.
8. Return the endpoint, method, content type, complete request fields, expected task/result fields, and the next polling or download step. Preserve original files unless replacement is explicitly requested.

Credentials

Store only the current skill's API key in the sibling api_key file. This file is private runtime state and must be excluded from version control and skill publishing.

To obtain an API key, register or sign in at ComPDF Portal. On first use, provide the key when requested and confirm storing it in the skill-local api_key file; later requests reuse that stored key.
