Secure digest functions are famously known as Cryptographic hash functions. It is a mathematical function that takes an input value and converts it into a meaningless output called a hash. The input to the hash function can differ to the occasion but the output always has a fixed length. …

In the previous article, we have talked about cryptography and symmetric key algorithms. So let’s dive into the Asymmetric key cryptography. Asymmetric Encryption Asymmetric encryption algorithms do not use one single key to encrypt and decrypt the information like symmetric encryption. Instead of using a single key, asymmetric encryption mechanism uses 2…

Cryptography is both the practice and the study of hiding information. In the old times, when comes to cryptography, it was all about encryption. that means methods for changing data from its ordinary, conceivable structure into a boundless state, making it inaccessible without the key. Data encryption methodologies were mostly…

RabbitMQ — Work Queue RabbitMQ is can be defined as an open-source message queuing application or a message broker. Which consists of functionalities like connecting between applications, transfer messages to consumers from queues etc. In here we consider messages as which includes information it could be a simple text message…

Java RMI stands for Remote method invocation. This technology is used for communication purposes of java virtual machines which are situated remotely. RMI method can invoke those remote methods in other machines and can transfer objects and can provide remote services as well. Protocols areconstantly used for communication where it…

Remote procedure call (RPC) is a protocol that helps one program to request service from another program located in another computer in a network. In this method, processes that are communicating does not need to understand network details because RPC takes care of that. …

Information stored in running programs is displayed as data structures. The data is independent of the form of communication used and data Structures must be flattened before transmission rebuilt on arrival. …
