PKCS7 Decrypt MIME

See more MIME Examples

Loads a PKCS7 encrypted MIME file and decrypts. The cert and private key used for decryption is loaded from a PFX file. Zig

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

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

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    const mime = try chilkat.Mime.init();
    defer mime.deinit();

    // Load the MIME
    mime.loadMimeFile("encryptedMime.txt") catch {
        std.debug.print("{s}\n", .{try mime.getLastErrorText(alloc)});
        return;
    };

    // The AddPfxSourceFile and/or AddPfxSourceData
    // methods may be called one or more times (one per PFX)
    // to add sources from which the MIME component will
    // search for certificates and private keys when decrypting.
    const pfx_password = "myPassword";
    mime.addPfxSourceFile("myCertAndPrivateKey.pfx", pfx_password) catch {
