Generate RSA Public/Private Key Pair and Export to PEM

See more RSA Examples

_LANGUAGE_ example code showing how to generate an RSA public/private key pair and export to PEM files. Zig

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

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

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

    const rsa = try chilkat.Rsa.init();
    defer rsa.deinit();

    // Generate a 2048-bit key.  Chilkat RSA supports
    // key sizes ranging from 512 bits to 8192 bits.
    const priv_key = try chilkat.PrivateKey.init();
    defer priv_key.deinit();
    rsa.genKey(2048, priv_key) catch {
        std.debug.print("{s}\n", .{try rsa.getLastErrorText(alloc)});
        return;
    };

    const pub_key = try chilkat.PublicKey.init();
    defer pub_key.deinit();
    priv_key.toPublicKey(pub_key) catch {};

    // Save the private key in PEM format:
    priv_key.savePemFile("privateKey.pem") catch {
        std.debug.print("{s}\n", .{try priv_key.getLastErrorText(alloc)});
        return;
