Encrypt and Decrypt username and Password in Automation

Recently, I came across a situation where we need to encrypt usernames and passwords so that they can not be hardcoded. This was my first experience to encounter this kind of situation in automation. So I read some java articles on how can we achieve it. 

I used java cipher, to do this activity. 

In java, You can create an instance for the cipher class and provide a mode that can be used for encryption.

Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");

Before using the cipher obect, you need to initialise it.

cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec);

The first argument is for to set mode (Encrypt/decrypt) and the second argument is to

for creating the secretKeySpec.

The secret key spec you can generate by:

public static void setKey(String mykey) {

    {

        try {

            key = mykey.getBytes(UTF_8);

            sha = MessageDigest.getInstance(CIPHER_ALGORITHM_SHA);

            key = sha.digest(key);

            key = Arrays.copyOf(key, 16);

            secretKeySpec = new SecretKeySpec(key, AES_ALGORITHM);

        } catch (NoSuchAlgorithmException e) {

            e.printStackTrace();

        } catch (UnsupportedEncodingException e) {

            e.printStackTrace();

        }

    }

}

The CIPHER_ALGORITHM_SHA is "SHA-1".

The base encoding is "UTF-8".

The ES_ALGORITHM is "AES".

When all is set, you can invoke the encrypt and decrypt with the help of doFinal method.

Base64.encodeBase64String(cipher.doFinal(StringToEncrypt.getBytes(UTF_8)));

String(cipher.doFinal(Base64.decodeBase64(encodedText)));

Let me know if anyone needs this utility. I will upload it to my GitHub repo.
