The given code is written in JavaScript.

Step 1: Import the 'crypto' module using the 'require' function.
```javascript
const crypto = require('crypto');
```

Step 2: Create a cipher object using the 'createCipher' method from the 'crypto' module. The cipher algorithm used here is 'aes192', and the password is set as 'a password'.
```javascript
const cipher = crypto.createCipher('aes192', 'a password');
```

Step 3: Encrypt the plaintext 'Hello JavaTpoint' using the 'update' method of the cipher object. The input encoding is 'utf8', and the output encoding is set as 'hex'.
```javascript
var encrypted = cipher.update('Hello JavaTpoint', 'utf8', 'hex');
```

Step 4: Finalize the encryption process using the 'final' method of the cipher object. The output encoding is again set as 'hex'.
```javascript
encrypted += cipher.final('hex');
```

Step 5: Print the encrypted text to the console.
```javascript
console.log(encrypted);
```

The output will be the encrypted version of the plaintext 'Hello JavaTpoint'.
