I’ve gotten most of the first part (including the private key), but somehow not able to decrypt the message. Using OpenSSL I get a size error “rsa routines:rsa_ossl_private_decrypt:data greater than mod len:…/crypto/rsa/rsa_ossl.c:401”
I’ve tried converting the message to other formats but it seems I’m not on the right path with this, possibly to do with padding used in the OpenSSL implementation. I’ve given some attempts at doing this in Python without luck either. A nudge on this part would be great.
