Assert function in C
Posted: 2021-10-05 14:31:34 Source: https://linuxhint.com/assert-function-c/
Assert function in C language helps us test out the program by checking the value of the expressions, which are supposed to be true in usual circumstances. It is extremely helpful due to its descriptive way of showing an error, making it easier for us to debug the program. How to use the assert function in C language is explained in this article.

In PuTTY, Scripted Passwords are Exposed Passwords
Posted: 2021-10-04 16:00:00 Source: https://www.linuxjournal.com/content/putty-scripted-passwords-are-exposed-passwords
PuTTY is one of the oldest and most popular SSH clients, originally for Windows, but now available on several platforms. It has won corporate support and endorsement, and is prepared and bundled within several third-party repositories.
Unfortunately, the 0.74 stable PuTTY release does not safely guard plain-text passwords provided to it via the -pw command line option for the psftp, pscp, and plink utilities as the documentation clearly warns. There is evidence within the source code that the authors are aware of the problem, but the exposure is confirmed on Microsoft Windows, Oracle Linux, and the package prepared by the OpenBSD project.
After discussions with the original author of PuTTY, Simon Tatham developed a new -pwfile option, which will read an SSH password from a file, removing it from the command line. This feature can be backported into the current 0.76 stable release. Full instructions for applying the backport and a .netrc wrapper for psftp are presented, also implemented in Windows under Busybox.
While the -pw option is attractive for SSH users who are required to use passwords (and forbidden from using keys) for scripting activities, the exposure risk should be understood for any use of the feature. Users with security concerns should obtain the -pwfile functionality, either by applying a patch to the 0.76 stable release, or using a snapshot release found on the PuTTY website.
Vulnerability
The psftp, pscp, and plink utilities are able to accept a password on the command line, as their usage output describes:

Shift Operators in C
Posted: 2021-10-02 20:15:47 Source: https://linuxhint.com/shift-operators-in-c/
The bits in an integer variable are shifted by a defined number of positions using two shift operators. It's used to move the bits of a value to the left by adding zeros to the empty spaces left after shifting. Employing the left and right shift operators instead of computing and then multiplication by a power of two will result in substantially faster code. How to use Shift operators in C is explained in this article.
