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)


To use the plugin, add simple_rsa as a dependency in your pubspec.yaml file.


First, add private and public key

final PUBLIC_KEY = "...";
final PRIVATE_KEY = "...";

After, you can encrypt text

and decrypt


See the example application source for a complete sample app using the Simple RSA encryption.
