## Usage

### Plain Text

```dart

final plainText = "Lorem ipsum dolor sit amet, consectetur adipiscing elit ........。本文基本上是将dart官网部分内容进行翻译，没兴趣的请出门左转至Dart的官网，有兴趣的同志请继续阅读本文。Flutter教程在这里通常，映射是一个有键和值的对象。 键和值都可以是任何类型的对象。 每个键只出现一次，但您可以多次使用相同的值。Dart的Map支持由映射文字和Map。int和double都是num的子类型。 num类型包括基本运算符，如+， - ，/和*，也是你可以找到abs()，ceil()和floor()以及其他方法的地方。 （按位运算符，如>>，在int类中有定义。）如果num及其子类没有您要想要内容，那dart：math库可能有您想要的。Dart字符串是一系列UTF-16代码单元。 您可以使用单引号或双引号来创建字符串：您可以使用{expression}将表达式的值放在字符串中。如果表达式是标识符，则可以跳过{}。 要获取对应于对象的字符串，Dart调用对象的toString()方法。为了表示布尔值，Dart有一个名为bool的类型。 只有两个对象具有bool类型：true和false，它们都是编译时常量。Dart的类型安全意味着您不能使用if（nonbooleanValue）或assert（nonbooleanValue）等代码。 相反，明确检查值，如下所示：也许几乎每种编程语言中最常见的集合是数组或有序的对象组。 在Dart中，数组是List对象，因此大多数人只是将它们称为列表。Dart列表文字看起来像JavaScript数组文字。 这是一个简单的Dart List：";

```

### Base64

```dart

try {

    // Base64 - Encode

    final base64Encoded = crypto.DYFCryptoProvider.yf_base64Encode(plainText);

    print("[Base64] encode: " + base64Encoded);

    // Base64 - Dncode

    final base64Decoded = crypto.DYFCryptoProvider.yf_base64Decode(base64Encoded);

    print("[Base64] decode: " + base64Decoded);

} catch (e) {

    print("e: $e");

}

```

### MD5

```dart

try {

    // MD5 - 32 Bits Encode

    final md5Hash = crypto.DYFCryptoProvider.md5Encode(plainText);

    print("[MD5] Hash: " + md5Hash);

    // MD5 - 16 Bits Encode

    final md5b16hash = crypto.DYFCryptoProvider.bit16md5Enconde(plainText);

    print("[MD5] 16 Bits Hash: " + md5b16hash);

} catch (e) {

    print("e: $e");

}

```

### AES

```dart

try {

    // AES Key

    // final aesKey = "smMQI8dMK2nOMUR0TdpBYQUnLpbW8kjHrdy86WtU6eB1Ff6mYveYzezopmbjwBZEjPQmg";

    final aesKey = "smMQI8dMK2";

    print("[AES] key: " + aesKey);

    // AES - Encrypt

    String aesEncryptedText = crypto.DYFCryptoProvider.aesEncrypt(plainText, aesKey);

    print("[AES] encryptedText: " + aesEncryptedText);

    // AES - Decrypt

    String aesDecryptedText = crypto.DYFCryptoProvider.aesDecrypt(aesEncryptedText, aesKey);

    print("[AES] decryptedText: " + aesDecryptedText);

} catch (e) {

    print("e: $e");

}

```

### RSA

```

// 公钥

final publicKey =
