Ciphering CLI Tool

Command utility for encoding / decoding ciphers:

• Caesar
• Atbash
• ROT-8/ROT-13

Command syntax

$ node cli-ciphering -c <configuration> [-i <input file path>] [-o <input file path:>]

where:

• "-с or --config" - names and sequence of execution of ciphers, example, "C1-C1-R0-A"
  • Caesar -> C1-encryption and С0-decryption with Caesar cipher
  • Atbash -> A encryption / decryption with Atbash cipher
  • ROT-8/ROT-13 -> R1-encryption and R0-decryption with ROT cipher
• "-i or --input" - input data file path
• "-o or --output" - output data file path

If the "-i or -o" options are not specified, then the input and output streams are considered stdin and stdout, respectively.

Examples of running the cli command

$ node cli-ciphernig -c "C1-C1-R0-A" -i "./input.txt" -o "./output.txt"
# C1-C1-R0-A: encodes with Caesar cipher => encodes with Caesar cipher => decodes with ROT cipher => Atbash transformation
# read from file, write to file

$ node cli-ciphernig --config "C1-C1-R0-A" --output "./output.txt"
# ... transformation ...
# read from stream `stdin`, write to file

$ node cli-ciphernig -с "C1-C1-R0-A"
# ... transformation ...
# read from the `stdin` stream, write to the `stdout` stream
