WeakRsa issue

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 “139862885470272:error:0906D06C: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

any suggestions?

Thanks :slight_smile:

Get familiar with RsaCtf tools :wink:
