the only thing that wasn't fun was installing libcrypto.so.1.1, but apart from that it's a good and fun chall

change jnz to jmp in IDA. ;)

i can't debug

Solved with z3 and Cutter. I didn't notice any anti-debugging techniques, and I'm curious. Can someone that experienced that tell me about it? Thanks.

wouldn't call myself more experienced but i guess "debugging" here means actually running the application and debugging the live state as opposed to static analysis?

ptrace(0,0,0,0) functions prevents you debug the program.

I liked the challenge, was annoying that I I had to have a specific version of openssl installed. Was quicker just to manually recover.
