I had used the earlier version OpenSSL 1.0.2s which ran perfectly as there was no such usage of DEPRECATEDIN_1_1_0 in bio.h while the new version 1.1.1d encloses the functions like BIO_get_port using DEPRECATEDIN_1_1_0 as bel… Continue reading OpenSSL 1.1.1d gives the error on DEPRECATEDIN_1_1_0 in bio.h
I am trying to overflow the buffer shown bellow, yet can never reach it. I know that the location of buf is before i and len, and in my case to overload the return instruction I need to amend the integer len. I know I need to… Continue reading Buffer Overflow
Microsoft releases monthly (or more frequent) patches to Windows operating systems which fix security issues. They also release updates to their SDKs which are used in C++ applications, but do they specifically fix security b… Continue reading Windows SDK Security Fixes
[Sandro Magi] noted that the async/await idiom has become more prevalent in programming recently. According to him, he first encountered it in C# but has found examples of it in JavaScript and Rust, too. The idea is simple: allow a function to return but come back later to complete something …read more
At first glance, it might not seem to make sense to write shell scripts in C/C++. After all, the whole point to a shell script is to knock out something quick and dirty. However, there are cases where you might want to write a quick C program to do something …read more

A lot of programming languages these days feature lambda functions, or what I would be just as happy to call anonymous functions. Some people make a big deal out of these but the core idea is very simple. Sometimes you need a little snippet of code that you only need …read more
I have been reading up on Buffer Overflows and NOP Sleds. I tried to use the exploit on an example target and I got stuck because I needed to inject a null byte in the return address for my BP so that my program does not cras… Continue reading Is a Buffer Overflow / NOP Slide possible for memory addresses that contain null bytes?
I need to store a key (symmetric-key cryptography) within my C++ application binary (based on OpenCV) so that the key as unidentifiable as possible. Can someone help me choose the key so that is secure and it will be difficul… Continue reading Prevent finding key in C++ application binary
I have the code to create a complete password list such as aaaaaaaa-zzzzzzzz. In other words brute force, every combo.
However this produces a file, many GBs large, and also takes forever running on hashcat, for example.
Ar… Continue reading What options are there to create password lists? [on hold]
I am doing my Master thesis, and the first part is to define the most important Secure Coding Guidelines to follow.
I know that ideally all of them should be followed, but developers tend to just think about getting their c… Continue reading What are the Secure Coding Guidelines of C and C++ that Developers should never miss? [on hold]
