Encryption and Decryption using Devglan.com

                        Encryption and Decryption using Devglan.com

Aim

To understand and demonstrate the process of encryption and decryption of data using the online encryption/decryption tool available at Devglan.com.

 

Introduction

In the modern digital world, data security is of utmost importance. Encryption is a process of converting readable data (plaintext) into an unreadable format (ciphertext) to protect it from unauthorized access. Decryption is the reverse process that converts the encrypted data back into its original form.
Devglan.com provides an easy-to-use online tool for testing and demonstrating various encryption algorithms like AES, DES, RSA, and Base64 encoding.

 

Encryption

Encryption is the process of encoding information in such a way that only authorized parties can read it. It uses an algorithm and an encryption key to transform plain text into ciphertext.
For example, AES (Advanced Encryption Standard) is a symmetric key encryption technique that ensures data confidentiality.

 

Decryption

Decryption is the process of converting the encrypted text (ciphertext) back into its original readable form (plaintext) using the correct key. Only users who possess the correct decryption key can successfully recover the original data.

 

Procedure

1. Open the website https://www.devglan.com/online-tools.
2. Select the desired encryption algorithm (e.g., AES Encryption).
3. Enter the plaintext message you want to encrypt in the input box.
4. Provide a secret key (and initialization vector, if required).
5. Click on Encrypt to generate the ciphertext.
6. Copy the ciphertext.
7. To decrypt, open the Decryption section of the same tool.
8. Paste the ciphertext and use the same key (and IV).
9. Click on Decrypt to get back the original plaintext.

Output

Example

Step	Input / Action	Output

Conclusion

Through this experiment, we learned how to use Devglan.com to perform encryption and decryption of data. This process helps ensure data security and privacy by converting readable text into secure, encoded formats that can only be decoded by authorized users. Understanding these techniques is essential for protecting sensitive information in communication and storage.
