Usage (Flutter/Dart)

Implementation

pubspec.yaml

encrypto_flutter: lastest

RSA

RSA Init

Encrypto encrypto = Encrypto(Encrypto.RSA); // or Encrypto(Encrypto.RSA, bitLength: 1024) or Encrypto(Encrypto.RSA, pw: 'foofoo78')
//this generates public and private keys for e2ee or initiates DES encryption

RSA Encrypt

String val = "alo";
String base64encrypted = encrypto.encrypt(val, publicKey);
//passing public key as 2nd parameter is MANDATORY for RSA encryption

RSA Decrypt

String decrypted = encrypto.decrypt(base64encrypted);
System.out.println(decrypted);
//prints original message i.e. "alo"

Other methods for RSA

Sr. number	Methods	Info
1	Encrypto.dart / getPublicKey()	is a method that returns generated ZotPublicKey
2	Encrypto.dart / desterilizePublicKey()	is a static method which converts ZotPublicKey string to ZotPublicKey
3	Encrypto.dart / sterilizePublicKey()	returns a ZotPublicKey string which can be sent to the other person.
4	Encrypto.dart / getPrivateKeyString() and getPublicKeyString()	returns plain text of private/public key exponent and modulus
5	Encrypto.dart / encrypt(String value, ZotPublicKey publicKey)	used to encrypt String with RSA
6	Encrypto.dart / public String decrypt(String value)	used to decrypt string using the password or ZotPrivateKey (no need to pass ZotPrivateKey or Password as parameter for decryption)
7	ZotPublicKey.dart / public String sterilizePublicKey() and public String encrypt(byte[] val)	same as no. 3 and no. 5 of the table
8	ZotPrivateKey.dart / public String decrypt(byte[] decode)	same as no. 7 of the table

DES

NOTE: DES might throw error for version 1.*

DES Init

Encrypto encrypto = new Encrypto(Encrypto.DES, "the moon is scary sometimes");
//MANDATORY to pass password as 2nd parameter for DES
//It's suggested to pass the hash of the password instead of plain text

DES Encrypt

String base64DESencrypted = encrypto.encrypt("alo");
//do not pass anything as 2nd parameter or pass null

DES Decrypt

String decrypted = encrypto.decrypt(base64DESencrypted);
//you get back the text
