Usage

From source file:aajavafx.Kripto.java

public String decrypt(String cipherText) throws Exception {
    Base64 decoder = new Base64();
    byte[] decodedBytes = org.apache.commons.codec.binary.Base64.decodeBase64(cipherText.getBytes());
    Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
    SecretKeySpec key = new SecretKeySpec(encryptionKey.getBytes("UTF-8"), "AES");
    cipher.init(Cipher.DECRYPT_MODE, key, new IvParameterSpec(IV.getBytes("UTF-8")));
    return new String(cipher.doFinal(decodedBytes), "UTF-8");
