In this research, we are calculating the encryption or decryption time taken by four types of symmetric-key encryption techniques to encrypt or decrypt data which are DES, 3DES, BLOWFISH, and TWOFISH. Each technique possesses different size data with a fixed-size key and also in the case of a fixed size data with keys of different sizes to analyze the excellence of a technique that aids in the comparative study of an encryption technique and make us choose the efficient one. The time taken by symmetric-key encryption or decryption technique to encrypt or decrypt some data with some key varies from one technique to the other and depends on the data size, device configuration, key size, processor load, etc. This paper also assists in choosing an encryption or decryption technique to encrypt or decrypt some data with some key under certain scenarios by providing actual plots and statistics generated for DES, 3DES, BLOWFISH, and TWOFISH encryption techniques for encrypting or decrypting data under different situations with the help of our own web application “PCrypt” that is created by us using technologies such as JavaScript, Bootstrap, JpGraph, PHP, HTML, CSS, etc.
