It had been in constant use as a server for almost two years, and this provided a good opportunity to start fresh and correct a few problems. After its initial installation, it began experiencing disk problems and the official Raspberry Pi operating system (OS) received a significant update (and was renamed from Raspbian to Raspberry Pi OS). So I acquired a new microSD card and preceded to rebuild.read more

Previously we talked about End to End Encryption, this time we will talk about Public Key vs Private Key in Cryptography. Before we start discussing their difference. We need to understand what they are and how they are used. Public and Private keys are the pair of two keys that are related to each other. These keys have a special purpose to serve, If you encrypt a packet of data with one key, that encrypted data packet can be decrypted with the other key of this pair.

patch set from Alexey Gladkov attempts to address the problem by way of
a not-entirely-obvious approach.
