URGENT: RSA clean source code in C

Hi,
I am looking for a clean source code of RSA written in C, without any libs or licenses attached. I checked most of the previous questions regarding this subject in EE but most of the provided links were broken, or they were prompting a licensed code.
Another important requirement is that the code will encrypt string or stream.
Thank you

Have a look at OpenSSL (http://www.openssl.org/) or libgcrypt (http://www.gnupg.org/). For C++, have a look at Crypto++ (http://www.cryptopp.com/).

aledev,
thank you for the prompt reply but the specific code can only have a key size of 32 bit and not 1024 bit in order to be secure. Moreover it's in C++ and the code quality is not good.

Infinity08,
I checked them, but I want something on its own and not as a part of a lib. Thank you

May I ask why ?

When it comes to security, it's best to go with a tried and tested solution (like one of the libraries I suggested), rather than rolling your own, or copying some code that floats around on the internet, or has been given to you in some other way.

You are absolute right but for the specific project i need it for I am not allowed to import any library

Anyway guys I think I am going to try and write the code by myself (although i do not know C). If i finally do it I ll post a link in order for others to find it. Thank you both for your time. Points will be split.

In that case, you can always look at the source code for those specific libraries, and get some inspiration from it, or simply copy the code you need (check the specific license, but usually that's allowed).
