Add PFX Bytes as a Decryption Source

See more MIME Examples

Loads a CMS/PKCS #7 encrypted S/MIME message and decrypts it back to the original MIME content.

AddPfxSourceBd registers PFX/P12 bytes held in a BinData as a source of certificates and private keys for later decryption.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    const mime = try chilkat.Mime.init();
    defer mime.deinit();
    mime.loadMimeFile("qa_data/encrypted.eml") catch {
        std.debug.print("{s}\n", .{try mime.getLastErrorText(alloc)});
        return;
    };

    // Add PFX/P12 bytes (from a BinData) as a source of certificates and private keys for later
    // decryption.  The 1st argument is the BinData and the 2nd is the password (from a secure source).
    const bd_pfx = try chilkat.BinData.init();
    defer bd_pfx.deinit();
    bd_pfx.loadFile("qa_data/recipient.pfx") catch {
        std.debug.print("{s}\n", .{try bd_pfx.getLastErrorText(alloc)});
        return;
    };

    const pfx_password = "myPfxPassword";
    mime.addPfxSourceBd(bd_pfx, pfx_password) catch {
        std.debug.print("{s}\n", .{try mime.getLastErrorText(alloc)});
        return;
    };

    mime.decrypt() catch {
        std.debug.print("{s}\n", .{try mime.getLastErrorText(alloc)});
        return;
    };

    std.debug.print("Decrypted.\n", .{});
