$1)$ Implement the DES system in C$++,$ java, Perl, etc., and the purpose of it is to train and enhance your programming skills using bit operations and manipulating bits in fluency. Then, decrypt the ciphertext string using the key$=$A$68$FDB$5$C$81430$E$92($in hexadecimal$).$ The decrypted plaintext should be in standard English text, not in hexadecimal.

The parameters for DES are listed below:
