"Encryption by date" is not a widely recognized or standard term in the field of cryptography. However, it may refer to a few concepts that involve the use of date-related information in encryption processes. 1. **Key Generation Based on Date**: Some encryption algorithms might use the date as a part of the key generation process. For example, a system might generate a unique encryption key based on the current date, which could be used for securing data.
Key stretching is a cryptographic technique used to increase the security of passwords or keys by making them longer and more complex. It involves applying a computational function repeatedly to a password or key, effectively transforming it into a more secure format. The primary goal of key stretching is to make it more difficult for an attacker to perform brute force attacks or dictionary attacks to recover the original password. The process typically involves the following steps: 1. **Input**: A weak password or key is provided as input.
Computer security organizations are groups or institutions that focus on protecting computer systems, networks, and data from unauthorized access, damage, theft, or disruption. These organizations may be involved in a variety of activities, including research, policy development, education, and the establishment of best practices in the field of computer security and information assurance. Here are some key types of computer security organizations: 1. **Government Agencies**: Many countries have government bodies dedicated to cybersecurity. Examples include: - **U.S.
MinID (Minimal Identifier) is a digital identity solution developed by the Norwegian government to provide secure access to various online services. It allows users to authenticate themselves using a secure, simplified method, ensuring that their personal information remains protected.

Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
