zpem

A pem parse and encode library for Zig.

Env

• Zig >= 0.14.0-dev.2851+b074fb7dd

Adding zpem as a dependency

Add the dependency to your project:

zig fetch --save=zpem git+https://github.com/deatil/zpem#main

or use local path to add dependency at build.zig.zon file

.{
    .dependencies = .{
        .zpem = .{
            .path = "./lib/zpem",
        },
        ...
    },
    ...
}

And the following to your build.zig file:

    const zpem_dep = b.dependency("zpem", .{});
    exe.root_module.addImport("zpem", zpem_dep.module("zpem"));

The zpem structure can be imported in your application with:

const zpem = @import("zpem");

• parse pem

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

    const bytes =

    const allocator = std.heap.page_allocator;
    var p = try zpem.decode(allocator, bytes);
    defer p.deinit();

    std.debug.print("pem type: {s}\n", .{p.type});
    std.debug.print("pem bytes: {x}\n", .{p.bytes});

    // get header data
    const header = p.headers.get("ABC").?;
    std.debug.print("pem header: {s}\n", .{header});
}

• encode pem

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

pub fn main() !void {
    const alloc = std.heap.page_allocator;
    
    // var pp = zpem.Block.initWithType(alloc, "RSA PRIVATE");
    var pp = zpem.Block.init(allocator);
    pp.type = "RSA PRIVATE";
    try pp.headers.put("TTTYYY", "dghW66666");
    try pp.headers.put("Proc-Type", "4,Encond");
    pp.bytes = "pem bytes";

    const allocator = std.heap.page_allocator;
    var encoded_pem = try zpem.encode(allocator, pp);

    std.debug.print("pem encoded: {s}\n", .{encoded_pem});
}
