DES-ECB Encrytion/Decryption
DES encryption is located in the des directory under the root directory The key is named deskey.txt The output from my commands using DES is in the des/output directory.
Each folder has a makefile. To compile the code, simply run the make command. To delete output files and compiled files, run make clean.
To encrypt a file using DES:
./DES_ECB_Enc -k deskey.txt -i plaintext.txt -o ciphertext.mydesecb
To decrypt a file using DES:
./DES_ECB_Dec -k deskey.txt -i ciphertext.mydesecb -o plaintext-des.txt
