Generate weak X509 certificate

Asked 2022-Apr-09 at 20:17

I need to generate weak certificate for CTF challenge using RSA and small modulus so it's factorable. It should be about 64 bits.

I've tried to generate that using OpenSSL as I would the normal one, but it forbids creating certificate with modulus lower than 512 bits for security reasons. So I've changed the source files of OpenSSL so it doesn't checks the bit length and recompiled that again. I was then able to create private key using smaller modulus, but trying to create certificate using that key (or new small one) evoked new error which I don't fully understand. I even wanted to evade the OpenSSL problem at all using Python, but that just showed that it uses OpenSSL too and had exactly same problems.

I need to generate weak certificate for CTF challenge using RSA and small modulus so it's factorable. It should be about 64 bits.

It's impossible to do that as a self-signed certificate, because proper RSA signing can't work with keys that small.

RSA-SSA-PKCS1_v1.5 is the shortest structured RSA signature padding, and it's structured as (per https://datatracker.ietf.org/doc/html/rfc8017#section-9.2):

How to include library in Erlang\OTP

Asked 2022-Mar-07 at 11:38

I'm new in RabbitMQ, I want to use rabbitmq with ssl (AMQPs). Now the issue is when I read the Erlang/OTP Requirements for TLS Support, and checked my erlang setup with command code:all_loaded(). I got list of modules that are loaded in erlang but not found which are required to use ssl over rabbitmq (public_key, crypto, asn1, and ssl).

Upon checking my C:/program files/ erl-24.2.1/lib, I have the folder for respective library but I'm not sure how can I enable those libraries.

Please help me to enable those libraries in erlang otp.

You're using it wrong :-)

You are trying to decrypt a MIME message stream. You can't do that.

The SecureMimeContext.Decrypt() and DecryptAsync() methods expect the encrypted content of the MIME message.

If your goal is to load the MimeMessage and decrypt it, you would change your code to this:

Issue installing cryptography on Raspberry Pi 2B (armv7h Arch Linux ARM) (python 3.9.8)

Asked 2022-Feb-05 at 19:41

I'm having some trouble installing the python cryptography package on my raspberry pi, specifically with python version 3.9.8 (installed with pyenv). The cryptography package is installed on my system using pacman (python-cryptography package), and thus works using the main python interpreter (3.10.1). However, I need some version of python 3.9 specifically for another package I am using in this project. Any time I try to install cryptography through the python 3.9.8 environment, I get the following error:

ANSWER

Answered 2022-Jan-14 at 19:59

@jakub's solution ended up solving the problem for me. I uninstalled the version of rust that was installed through pacman. To replace it, I installed rustup and then using rustup, installed the latest nightly version of rust (1.60). Once I did that, installing the cryptography package worked just fine.

If you are using rustup, just make sure that you add ~/.cargo/bin to your PATH before installation. Also, the command I used to install rust through rustup was rustup toolchain install nightly.
