With the increasing concerns about data security and privacy, encrypting sensitive information has become crucial. This extends beyond just text data to multimedia files like videos. Encrypting videos adds an extra layer of security, ensuring that even if unauthorized individuals gain access to the files, they cannot view the content without the decryption key.

In this guide, we'll explore how to implement video encryption and decryption in Java, a popular programming language known for its versatility and robustness.

Video Encryption

Read Video File: Use Java I/O classes like FileInputStream to read the video file into a byte array or a stream.

Encrypt the Video: Utilize the chosen encryption algorithm to encrypt the video data. This involves creating an encryption key and initializing a cipher with this key.

Write Encrypted Data to File: Once the video is encrypted, save the encrypted data to a new file using FileOutputStream or other appropriate methods.

Video Decryption

Read Encrypted Video File: Similar to encryption, use Java I/O classes to read the encrypted video file into memory.

Decrypt the Video: Initialize a cipher with the decryption key and use it to decrypt the encrypted video data.

Write Decrypted Data to File: After decryption, save the decrypted video data to a new file using appropriate I/O operations.

Sample Code
