at_cram_single (digest in one command)

[JeremyTubongbanua]

- What I did

• Create at_cram_single.dart to work with manual input for cram digesting
• Add at_cram_single documentation to at_cram/README.md
• Usage: dart bin/at_cram_single.dart <cramSecret> <challenge>

- How I did it
See at_cram_single.dart

- How to verify it

Might also be a great idea to use

https://pub.dev/packages/args

to help with the command line code

Example here

@cconstab

Thank you for the feedback! :D
I've implemented ArgParser to at_cram's pubspec.yaml (c2d5752),

Implementation can be seen here: 27345ee

An example can be seen below

Incorrect usage output

> dart at_cram/bin/at_cram_single.dart -k c5544195f973eb40375f7f4b504ec631c35a8c7ec90e0a353242010880afac5bb6a9566be8d0f5947da697b5f01f651e92297622e49cf06844afb14d7c8e7a5d

CRAM digesting in one single line
  --cramSecret -k       | cramSecret received when you initially get an @ sign (usually in the form of a QR code)
  --challenge -c        | the challenge response you receive after doing `from:@youratsign`, will respond with `data:<challenge>`
  Example: `dart bin/at_cram_single.dart -k cramSecret123 -c fromChallenge123`
