i have made a text file named examplefile.txt, then used the command in-toto-keygen -t rsa -b 4096 examplefile.txt
, it created 2 files { examplefile.txt, examplefile.txt.pub }, i am not able to upload the examplefile.txt.pub file here as it is greyed out, as i readed the doc the commandline created an rsa key pair, so i have uploaded the first file examplefile.txt ( with some alteration in the rsa key so that i am at a safer side. hope this helps.
examplefile.txt

Hi @ashutoshsao, could you open a PR? Also, consider taking a look at #22 as well. If this is a key created just for this purpose and it's not used for anything, it should be okay to upload without any changes.
