I have the private key done manually couple of times and with known tools
but when i try to read the encrypted flag
openssl rsautl -decrypt -inkey flag.enc < private.key
i get "1398628854702720906D06C:PEM routines:PEM_read_bio:no start line:../crypto/pem/pem_lib.c:691:Expecting: ANY PRIVATE KEY"
googled a lot most of the posts i saw said to make sure i have ----begin rsa.......
it does i have the rsa key an i am pretty sure i got the right one
