esse PDF não tem senha

Error message

esse PDF não tem senha

What it means

password_one in 'remove' mode requires an actually-encrypted document. If doc.is_encrypted() is false AND no current_password was supplied, there is nothing to strip, so the function returns 'esse PDF não tem senha' instead of pointlessly rewriting the file.

Solutions

1. Check the PDF is actually encrypted before invoking (qpdf --show-encryption file.pdf, or doc.is_encrypted())
2. Only call password(mode="remove") for documents reported as password-protected
3. If the intent was to add a password, use the add/set mode instead of "remove"

Example fix

// before
password_one(&PasswordOptions { mode: "remove", ..Default::default() }, input)?;
// after
if is_pdf_encrypted(input) {
    password_one(&PasswordOptions { mode: "remove", ..Default::default() }, input)?;
}

if mode == "remove" && !is_pdf_encrypted(input) && current_password.is_empty() {
    anyhow::bail!("nada a remover: o PDF já está aberto");
}

match password_one(&opts, input) {
    Ok(item) => item,
    Err(e) if e.to_string().contains("não tem senha") => Ok(WriteItem::noop(input)),
    Err(e) => return Err(e),
}

When it happens

Trigger: Calling password with mode="remove" on a PDF that has no encryption dictionary and no current_password set in PasswordOptions.

Common situations: User drags an unprotected PDF into a 'remove password' flow; a previous run already removed the password; caller misinterprets 'remove' mode as generic re-save.
