A terminal program that parses & encrypts/decrypts data according to its
provided algorithm, mode, & key arguments. The program is also able to
read/write data to/from selected files within the default .test directory inside
the program's parent directory. If in/out files are not specified, then the
program prints the encrypted/decrypted results to the console. Flags
are interchangeable across one another & their ordering does not matter.
| FLAGS | ARGUMENTS | DEFAULTS |
|---|---|---|
| -alg | shift, unicode | shift |
| -mode | enc, dec | enc |
| -key | <number> | 0 |
| -data | "<string_data>" | "" |
| -in | <file_name.extension> | "" |
| -out | <file_name.extension> | "" |
-alg shift -mode enc -key 10 -data "Hello, World!"
Rovvy, Gybvn!
-key 10 -data "Rovvy, Gybvn!" -mode dec -alg shift
Hello, World!
Files to be encrypted/decrypted must be placed within a .test folder in the
repository's parent directory to allow the program to discover them by default,
else defaultPath in parseEncryptDecrypt function must point to the preferred directory.
val defaultPath = System.getProperty(USER_DIR) + "${File.separator}.test${File.separator}"- Map
