Tested on Windows 10, 64 bit
Uses Python 3.6

Run python -m pip install -r requirements.txt to install all dependencies for the program.

The CLI for the program is developed to be separate for RabinKarp as well as RSA.

The general for of the Rabin-Karp CLI is shown below.

python rabin_karp.py match|verify <Text In File> [<Pattern File>] [Out File] [Radix] [Prime Bit Length]

Some example commands are shown below.

• Find all shifts in file text.txt using the pattern in file pattern.txt
  python rabin_karp.py match text.txt pattern.txt
• Find all shifts in file text.txt using pattern entered from the keyboard
  python rabin_karp.py match text.txt
• Find all shifts and save it to a file “out2.txt”
  python rabin_karp.py match text.txt pattern.txt out2.txt
• Verify all shifts found from file “big.txt” using pattern in file “pattern.txt”, with shifts from the Rabin Karp matcher stored in “out2.txt”
  python rabin_karp.py verify big.txt pattern.txt out2.txt

The general form of the CLI for the RSA program are shown below.

python rsa.py genkey|encrypt|decrypt|gendata <Input file> <output file> <Key File>

Some example commands are shown

• Generating a Public-Private Keypair of length 64 bit (default), and save to files <keypair_{public|private}.key>
  python rsa.py genkey
• Generating a Public-Private Keypair of length 128bits, and save it to file “key_{public|private}.key>
  python rsa.py genkey key 128
• Generating 1000 19 digit numbers at random, and store it to file “cc.txt”
  python rsa.py gendata cc.txt 1000
• Encrypting file “cc.txt” and saving the output to file “cc_e.txt” using default keypair
  python rsa.py encrypt cc.txt cc_e.txt
• Decrypting file “cc_e.txt” and save output to file “cc_d.txt” using default keypair
  python rsa.py decrypt cc_e.txt cc_d.txt
• Decrypting file “cc_e.txt” and save output to file “cc_d.txt” using keypair key2_{public|private}.key
  python rsa.py decrypt cc_e.txt cc_d.txt key2
