LinkerDesign.Crypto 0.3.2

LinkerDesign.Crypto

A lightweight crypto library which could run on browser, node, java(jvm), dotnet platform base on openssl libcrypto library.

1. browser, node package

we use webassembly technology to port and encapsulate the native c library(openssl libcrypto). you could access the npm package here

2. dotnet package

we use p/invoke technology to port and encapsulate the native c library(openssl libcrypto) . you could access the dotnet package here

3. java(jvm) package

we use jni(java native interface) technology to port and encapsulate the native c library(openssl libcrypto). you could access the maven central package here

Features

1. Symmetric Encryt Decrypt

• AES-CBC
• AES-CTR

2. Message Digest

• Sha1
• Sha256
• Sha384
• Sha512
• Md5
• Md5Sha1

more features will come soon!

Setup

dotnet add reference LinkerDesign.Crypto

usages

1. AES-CBC

We can use AES-CBC to encryt a string who's encoding is utf8 to a base64 string.

Additional, we can AES-CBS to decrypt a base64 string to it's original utf8 string

using LinkerDesign.Crypto;
using System.Text;

var msg = "《青溪》是唐代诗人王维创作的一首五言古诗。此诗描写了一条青溪的幽秀景色，诗人用多彩的画笔，绘出青溪流经不同地方时呈现的不同画面。其中“声喧乱石中，色静深松里”两句，以喧响的声音和幽冷的色调形成闹与静的强烈对比，如同一幅“有声画”。诗的末四句写出诗人心境的闲谈正如清川的闲淡，把自己的精神和自然的精神融和起来，意味隽永。全诗自然清淡素雅，写景抒情皆轻轻松松，然而韵味却隽永醇厚。诗人笔下的青溪是喧闹与沉郁的统一，活泼与安详的揉合，幽深与素静的融和。";

var aes = new Aes();

string key = aes.GenerateKey(EncodingType.Base64);
string iv = aes.GenerateIV(EncodingType.Base64);

var enc = aes.Encrypt(key, iv, msg, EncodingType.UTF8, EncodingType.Base64, EncodingType.Base64);
var dec = aes.Decrypt(key, iv, enc, EncodingType.Base64, EncodingType.Base64);

var decMsg = Encoding.UTF8.GetString(dec);

Console.WriteLine($"{dec}:::equals:{msg == decMsg}");

2. Message Digest

support regular message digest algorith, like sha1, sha256, md5 etc...
