Is my code implementing a Factory pattern ? Is this a bad design?

I am new to software design patterns and trying factory design (creational pattern) to implement in my application for encryption/decryption using key.

I want to make sure this is Factory pattern and if its a bad design. Also if you can help how to improve it .

My code is follows :

abstract base class :

public abstract class EncryptDecrypt {
protected Key getKey() {
    Key key = new SecretKeySpec(getKeyValue().getBytes(), getAlgorithm());
    return key;
}
protected Cipher getCipher() throws NoSuchAlgorithmException, NoSuchPaddingException {
    Cipher c = Cipher.getInstance(getAlgorithm());
    return c;
}

protected abstract String getKeyValue();
protected abstract String getAlgorithm();

public final String encryptText(String valueToEnc) throws IllegalBlockSizeException, BadPaddingException, InvalidKeyException, NoSuchAlgorithmException, NoSuchPaddingException {
    String keyValue = getKeyValue();
    String algorithm = getAlgorithm();
    Key key = getKey();
    Cipher c = getCipher();
    c.init(Cipher.ENCRYPT_MODE, key);
    byte[] encValue = c.doFinal(valueToEnc.getBytes());
    String encryptedValue = new String(Base64.getEncoder().encode(encValue));
    return encryptedValue;
}

public final String decryptText(String encryptedValue) throws InvalidKeyException, IllegalBlockSizeException, BadPaddingException, NoSuchAlgorithmException, NoSuchPaddingException {
    String keyValue = getKeyValue();
    String algorithm = getAlgorithm();
    Key key = getKey();
    Cipher c = getCipher();
    c.init(Cipher.DECRYPT_MODE, key);
    byte[] decordedValue = Base64.getDecoder().decode(encryptedValue);
    byte[] decValue = c.doFinal(decordedValue);
    String decryptedValue = new String(decValue);
    return decryptedValue;
}
}

and following is a sample AES implementation :

public class AESEncryptDecrypt extends EncryptDecrypt {

@Override
protected String getKeyValue() {
    return "ThisIsA Key 1234";
}

@Override
protected String getAlgorithm() {
    return "AES";
}
}

Client class :

public class Test {

public static void main(String[] args) throws Exception {
    EncryptDecrypt ed = new AESEncryptDecrypt();
    String msg = "Text message@yahoo.com";
    String e = ed.encryptText(msg);
    System.out.println(e);
    System.out.println(ed.decryptText(e));
}

}

Thank you so much for taking the time to answer.
