Open Password-Protected PDFs in JavaScript

PSPDFKit for Web supports opening and editing password-protected PDFs. Passwords can be supplied when loading a PDF, when entered by a user when accessing a document, or when included in the JSON Web Token (JWT).

Setting the Default Document Password

To supply the password when loading a PDF, set the password via the initial Configuration#password option:

PSPDFKit.load({
  password: "secr3t",
  ...,
});

PSPDFKit.load({
  password: "secr3t",
  ...
});

Note that setting this property will make loading PDF documents that aren’t protected by a password fail. As such, be sure to only add it for documents protected by a password.

Including the Password in the JWT (PSPDFKit Server Only)

To include the password in the JWT used by the optional PSPDFKit Server to authenticate clients, add the password claim to your JWT:

jwt.sign(
  {
    document_id: document_id,
    password: "secr3t"
    // ...
  },
  fs.readFileSync("./jwt.pem"),
  {
    algorithm: "RS256",
    expiresIn: 10 * 365 * 24 * 60 * 60 // 10 yrs
  }
);

jwt.sign(
  {
    document_id: document_id,
    password: "secr3t"
    // ...
  },
  fs.readFileSync("./jwt.pem"),
  {
    algorithm: "RS256",
    expiresIn: 10 * 365 * 24 * 60 * 60 // 10 yrs
  }
);

User Enters the Password

If the password is neither included in the JWT or set via the Configuration#password option, the user will be asked to enter the password via a password prompt.
