Sign a PDF-document using PKCS#7 digital signatures.

    pub fn sign_pkcs7(
        &self,
        num: i32,
        sign_data: &[u8],
        psw_sign: &str,
        set_x_indent: i32,
        set_y_indent: i32,
        set_height: i32,
        set_width: i32,
        reason: &str,
        contact: &str,

        is_visible: bool,
        appearance_data: &[u8],
        filename: &str,
    ) -> Result<(), PdfError>

Arguments

• num - the page number (1-based)
• sign_data - the raw bytes of the signature (PKCS#7 specification in Internet RFC 2315)
• psw_sign - the password of the signature
• set_x_indent - the x indent of the signature
• set_y_indent - the y indent of the signature
• set_height - the height of the signature
• set_width - the width of the signature
• reason - the reason of a signature
• contact - the contact of a signature
• location - the location of a signature
• is_visible - the visiblity of signature
• appearance_data - the raw bytes of the graphic appearance for the signature
• filename - the path to the resulting PDF-document with signature

Returns

• Ok(()) - if the operation succeeds
• Err(PdfError) - if the operation fails

Example

use asposepdf::Document;
use std::fs;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Read certificate and image files into byte vectors
    let cert = fs::read("sign.pfx")?;
    let img = fs::read("sign.png")?;

    // Open a PDF-document with filename
    let pdf = Document::open("sample.pdf")?;

    // Sign a PDF-document using PKCS#7 digital signatures
    pdf.sign_pkcs7(
        1,
        &cert,
        "Pa$$w0rd2023",
        100,

        "Location",
        true,
        &img,
