Description:
crypto x
crypto_x #
A Dart library for encryption and decryption. Advanced RSA, AES based on pointycastle.
Features #
RSA with PKCS1 and OAEP encoding.
Generate RSA KeyPairs and import to pem format.
Getting started #
Add the package to your pubspec.yaml:
dependencies:
crypto_x: <latest_version>
copied to clipboard
Usage #
AES #
Supported modes are:
CBC AESMode.cbc
CFB-8 AESMode.cfb8
CFB-128 AESMode.cfb
CTR AESMode.ctr
ECB AESMode.ecb
OFB-128 AESMode.ofb
final key = CipherKey.fromUtf8('your key................');
final iv = CipherIV.fromLength(16);
var aes = AES(key: key, mode: AESMode.cbc);
CryptoBytes encrypted = aes.encrypt(CryptoBytes.fromUTF8('hello world.'), iv: iv);
String encryptedBase64 = decrypted.base64;
CryptoBytes decrypted = aes.decrypt(encrypted, iv: iv);
String plainText = decrypted.toString();

RSA #
encrypt and decrypt
var privateRSA = RSA(
privateKey: privateKey);
var publicRSA = RSA(
publicKey: publicKey);
CryptoBytes signature = publicRSA.encrypt(CryptoBytes.fromUTF8('hello world'));
String ciphertext = signature.base64;
CryptoBytes plainBytes = publicRSA.decrypt(signature);
String plainText = plainBytes.toString();
copied to clipboard
sign and verify
var rsaSigner = RSASigner(digestType = DigestType.sha256, privateKey: privateKey, publicKey: publicKey);
var plainBytes = CryptoBytes.fromUTF8('hello world');
CryptoBytes signature = rsaSigner.sign(plainBytes);
bool isSame = rsaSigner.verify(signature, plainBytes);
