Workflow Playbook
Protect files and selected data fields, open encrypted PDFs with authorized credentials, set or remove permissions, and verify reversible output and reader compatibility.
Hubs
Use this workflow only for files, fields, and credentials that you are authorized to handle. Keep the original input, a recovery copy, and the working output distinct. Before choosing a tool, write down whether the handoff needs whole-file encryption, selected-field protection, PDF conversion, an open password, permission limits, or an authorized removal of restrictions. A password or encrypted bundle is an access mechanism for the stated scope, not a universal security guarantee.
Use aes-encryption-tool when the complete text or file should be encrypted and later restored with the associated IV-based bundle. For a CSV, use field-encryptor for named columns and field-decryptor for a controlled restore check. For an Excel workbook, use excel-field-encryptor and excel-field-decryptor, then inspect the restored workbook in the application that will receive it. In both field workflows, verify that non-target data and the file contract survive the operation.
If the goal is to read a password-protected PDF, encrypted-pdf-converter needs the correct authorized password before it can export Markdown, JSON, or text. Compare representative pages, headings, tables, and text spans after conversion; an opened file does not guarantee complete extraction. If the goal is a new delivery policy, use pdf-password-protector or pdf-permissions-set to apply the approved open-password and permission settings. Use pdf-permissions-remove only after the document owner has approved the change.
A useful acceptance check has two parts: reversibility and compatibility. Restore an authorized sample and compare it with the source, then open the final file in the named PDF reader, spreadsheet application, or downstream parser. Record changed metadata, unsupported features, permission behavior, and residual uncertainty. This produces a defensible delivery record without claiming that a local tool run replaces key management, governance, or compliance review.
Workflow playbook
For a general text or file payload, use AES encryption when the whole artifact should be protected. Keep the exported IV-based bundle with the authorized recovery instructions, and test decryption on a copy before treating the result as ready for delivery.
Choose the CSV field encryptor for named sensitive columns and retain the original row structure. Use the field decryptor only for an authorized restore check; compare the selected values with the source and verify that unrelated columns, delimiters, and encoding still meet the receiving system's contract.
For XLSX or XLS workbooks, identify the exact fields or columns that may change, run the matching Excel encryptor, and use the decryptor for a controlled round trip. Open the restored workbook in the intended spreadsheet application and check formulas, sheet structure, and non-target values where those are part of the handoff.
Use aes-encryption-tool for a general text or file-level AES operation with its exported IV-based bundle. Choose field-encryptor or excel-field-encryptor when the surrounding CSV or workbook must remain usable and only named values should change; use the matching decryptor only with the authorized method and material.
Use encrypted-pdf-converter when the goal is to read or convert a password-protected PDF and the correct password is available. Use pdf-password-protector or pdf-permissions-set to create a controlled delivery, and pdf-permissions-remove only when the owner has approved removal.
A successful local operation is not enough. Compare an authorized decrypted sample with the source, confirm that non-target fields and PDF pages are preserved, inspect the configured permissions in a representative reader, and test the actual downstream format or handoff.
When an authorized password is available, use the encrypted PDF converter to read the protected document and export the required Markdown, JSON, or text. Confirm that the password belongs to the approved document and compare representative headings, pages, tables, or text spans instead of assuming extraction is complete.
For a delivery PDF, use the password protector or permissions-set tool to apply the approved open-password and print or copy policy. If restrictions must be removed, use permissions-remove only with explicit owner authorization; then open the output in a representative reader and record the observed access behavior and any compatibility limits.
