Choosing encryption algorithms
There are many different encryption algorithms that you can choose from when trying to achieve one of the goals of cryptography. Let's talk about some of the things that you should watch for when selecting an encryption algorithm. It's important to remember that encryption is very complicated. It uses sophisticated mathematical techniques, and even the smallest flaw in an algorithm can render that algorithm insecure. For this reason, you should never try to build your own encryption algorithm unless you really, really know what you're doing. You wouldn't try to perform heart surgery on yourself. Don't try to build your own encryption algorithms either. Similarly, if a vendor claims that their software is secured with a proprietary encryption algorithm and they won't share the details, view that claim with the skepticism that it deserves, it's a big red flag. In fact, the idea of having secret encryption algorithms is so contrary to the principles held by cybersecurity professionals…
