# Visual Crypto Coding

- Visual Crypto Coding is a cryptographic technique that involves encrypting an input image using a randomly generated key.

- The encrypted image can then be decrypted using either the same key (in symmetric encryption) or different keys (in asymmetric encryption methods).

- This technique is particularly useful for ensuring the secure transmission and storage of sensitive images.

- In addition to generating encrypted images, this process also yields decrypted images to verify data integrity.

- This involves ensuring that the decrypted images obtained from all cryptographic algorithms match the original input image, thereby confirming the accuracy of the encryption and decryption processes.

- Further improvements can be done to improve data confidentiality, efficiency of the codes. Please feel free to submit a pull request.

## Encryption Time

- The encryption time of all the four algorithms are obtained as follows in EncryptTime.txt file

  | Algo | Time         |

  |------|--------------|

  | DES  | 4939747699 ns|

  | 3DES | 4500023999 ns|

  | AES  | 4476420593 ns|

  | RSA  | 5360362883 ns|

## Key Takeaways

- Conducted thorough performance analysis, revealing the AES algorithm with an encryption time of 4.47 secs, outperforming other algorithms by 10.02% on average.

- This highlights the superior efficiency and security of AES compared to the other algorithms.
