Calculate MD5 Hash of File (or SHA1, SHA256, and other hash algorithms)

See more Encryption Examples

Demonstrates how to calculate a hash for a file's contents. 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 crypt = try chilkat.Crypt2.init();
    defer crypt.deinit();

    // Set the name of the hash algorithm.
    // Other choices include "sha1", "sha256", "sha384", "sha512", "md2", "md5", and "haval".
    crypt.setHashAlgorithm("md5");

    // EncodingMode specifies the encoding of the hash output.
    // It may be "hex", "url", "base64", or "quoted-printable".
    crypt.setEncodingMode("hex");

    // Files of any type may be hashed -- it doesn't matter
    // if the file is binary or text...
    const hash_str = crypt.hashFileENC(alloc, "/temp/something.dat") catch {
        std.debug.print("{s}\n", .{try crypt.getLastErrorText(alloc)});
        return;
    };
