Obs: The version 1.0.0 have a problem with Asymmetric keys

Usage Symmmetrical Key

Your key need 14 bytes to work.

Encryption

import io.github.mrspock182.Encryption;
import io.github.mrspock182.constant.Cipher;
import io.github.mrspock182.constant.TypeEncryption;
import io.github.mrspock182.constant.Unicode;
import io.github.mrspock182.encryption.EncryptionSymmetrical;

Encryption encryption = new EncryptionSymmetrical(TypeEncryption.AES, Unicode.UTF8,
                "{YOUR_KEY}", Cipher.PKCS5PADDING);
        String encryptSymmetrical = encryption.encrypt("WORD TO ENCRYPT");
        System.out.println(encryptSymmetrical);

Decryption

import io.github.mrspock182.Decryption;
import io.github.mrspock182.constant.Cipher;
import io.github.mrspock182.constant.TypeEncryption;
import io.github.mrspock182.constant.Unicode;
import io.github.mrspock182.decryption.DecryptionSymmetrical;

Decryption decryption = new DecryptionSymmetrical(TypeEncryption.AES, Unicode.UTF8,
                "{YOUR_KEY}", Cipher.PKCS5PADDING);
        String decryptSymmetrical = decryption.toString("TIlt3ujfxpp_bLrOLL3S-A==");
        System.out.println(decryptSymmetrical);

Usage Asymmetric Key

Generate Public And Private Keys

import io.github.mrspock182.GenerateKey;
import io.github.mrspock182.constant.TypeEncryption;
import io.github.mrspock182.generate.GenerateAsymmetricKey;

GenerateKey generate = new GenerateAsymmetricKey(TypeEncryption.RSA, 
"{FILE_PATH}", {SIZE_KEY});
generateKey.generate();

Encryption

import io.github.mrspock182.Encryption;
import io.github.mrspock182.constant.TypeEncryption;
import io.github.mrspock182.constant.Unicode;
import io.github.mrspock182.encryption.EncryptionAsymmetric;

Encryption encryption = new EncryptionAsymmetric(Unicode.UTF8,
                TypeEncryption.RSA, "{FILE_PATH}/public.key");
String value = encryption.encrypt("WORD TO ENCRYPT");
System.out.println(encryptSymmetrical);

Decryption

import io.github.mrspock182.Decryption;
import io.github.mrspock182.constant.TypeEncryption;
import io.github.mrspock182.constant.Unicode;
import io.github.mrspock182.decryption.DecryptionAsymmetric;

Decryption decryption = new DecryptionAsymmetric(Unicode.UTF8,
            TypeEncryption.RSA, "{FILE_PATH}/private.key");
String value = decryption.toString("VALUE ENCRYPTED");
