Description. DES.java generates the sysmetric key using DES algorithm. Key size assigned here is 64 bits. It works only for the key size of 64 bits. 56 bits is mentioned in the coding remaining 8bits is accessed from inbuilt package.
In my program, before you can decrypt a string, you are prompted to enter a key. After you enter the correct c key,the string is decrypted. The problem is that the plaintext appears at the same time with the key form.The key should be entered first and verified then the plaintext to appear later. I have the following objects on my form.

When we have our nonce and ciphertext separated, we can decrypt the data and return it as plaintext. Encrypting and Decrypting Files. Encrypting and decrypting data as we demand is cool, but what if we wanted to encrypt and decrypt files. One way to handle file encryption is to take what we’ve already done and just use the file commands.
