Demystifying Encryption Key(s)
An encryption-key is a utility used for cryptography, in the transformational process coding/decoding of data and information, for security, easy transmission, and/or storage. Plaintext is ‘converted’, or encrypted, using an algorithm (called cipher – see elsewhere), to make it illegible, non-readable to anyone else, (except those possessing special knowledge) or ‘the encryption-key’, used and needed in order to de-cipher.
This results in encrypted information (or cipher-text – see elsewhere). Decryption is then needed to make the encrypted information readable yet again.
It enables secure and/or secret communication, protecting information, files, folders, systems, computers, storage devices (e.g. USB flash drives), networks (e.g. the Internet, e-commerce), mobile telephones, wireless microphones, wireless intercom systems, Bluetooth devices and even ATM’s
Another use for this is to set up and manage, control and maintain, edit/change, update, expand, customize, digital rights management. Encryption keys and lists are used to prevent unauthorized use, access or reproduction of copyrighted material, protection against reverse engineering et al.
An encryption key can protect the confidentiality of messages. There are standards and codes to assist in getting this in place. Care and caution has to be taken with system design and/or execution, pertaining to the encryption specifically. Symmetric encryption, or secret-key, shared secret methodology is accepted practice and a basic skill in your .NET Frameworks toolkit.
Consider closely and review all relevant content, chapters and references pertaining to: understanding and mastering of the basics pertaining to encryption and decryption tools, rules, access, modification, implications, choosing the algorithm, symmetric and asymmetric encryption, processes and keys, classes and algorithms, (types, dynamics, benefits and limits), setting up a symmetric/asymmetric or encryption keys, using it in messages, files, exporting and importing encryption key pairs, storing these for later use, hashes and digital signatures.

Key Exam Points
- Use Encryption Keys, Encryption Processes (Asymmetric, Symmetric, Hash, Digital Signatures, for C# and VB, .NET Framework solutions and environments), for improved security and performance.
- For the exam, study practical, hands-on, illustrative, real-life scenarios, work-labs and examples for Encryption Keys and Processes, that help you to gain a better in-depth, understanding of this topic and its related aspects, implications, risks, benefits and results.
- Take the practice test questions and exam work-labs (Q&A Samples with solutions - Multiple-Choice, Application)
