Simple RSA Encryption
Flutter plugin to encrypt, decrypt (RSA/ECB/PCSK1), verify and sign string with a public and a private key
Support for ANDROID and iOS(thanks to adlanarifzr)
Installation
To use the plugin, add simple_rsa as a
dependency in your pubspec.yaml file.
Usage
First, initialize private and public key. Preferably in BASE64 format.
final publicKey = '...';
final privateKey = '...';
After that, you can encrypt or decyrpt text
let plainText = 'something';
final encryptedText = await encryptString(plainText, utf8.decode(base64.decode(publicKey)));
final decryptedText = await decryptString(encryptedText, utf8.decode(base64.decode(privateKey)));
// Test
print(plainText == decryptedText ? 'true' : 'false');
Or you might want to sign and verify text
let plainText = 'something';
final signedText = await signString(plainText, utf8.decode(base64.decode(privateKey)));
final verified = await verifyString(plainText, signedText, utf8.decode(base64.decode(publicKey)));
// Test
print(verified ? 'true' : 'false');
Example
See the example application source for a complete sample app using the Simple RSA encryption.
