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, 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');
See the example application source for a complete sample app using the Simple RSA encryption.
Adlan Arif Zakaria (adlanarifzr) iOS compatibility, sign and verify method.
- Migrate to AndroidX
- Edit encryptData for support input size greater then 512 bytes
- Fixed iOS functions and optimize the code
- Add method for decrypt string (more 512 byte) with public key (ANDROID)
- Add iOS compatibility
- Add signData and verifyData method
- Initial experimentation
Demonstrates how to use the simple_rsa plugin.

Package is pre-v0.1 release. (-10 points)
While nothing is inherently wrong with versions of
0.0.*, it might mean that the author is still experimenting with the general direction of the API.
