Securing Images Using Encryption & Decryption

A quick and reliable security systems or APIs are required since the communication domain and interactive media data, such as movies and photographs, are expanding exponentially. Encryption is one method of protecting our data from unauthorized users when communicating and sharing files. The proposed API in this paper aims to secure images by utilizing a well-known Data Encryption Standard (DES) algorithm. The National Institute of Standards and Technology adopted IBM's Data Encryption Standard (DES) algorithm, a symmetric-key block cypher, in the early 1970s (NIST). Using 48-bit keys, the method transforms plain text, which is provided in 64-bit blocks, into ciphertext. Because DES can only convert plain text into secure cypher text, the Image encryption API first converted the image into a binary array so that the DES algorithm could be applied to the image in binary form. Using the API, each image to be transferred is first encrypted by selecting an encryption key. The image can only be opened by the receiver using the same key and API that the sender used during encryption. The primary need for this API or model is to ensure communication security and privacy.
