In cryptography, encryption is the process of encoding a message or information in such a way that only authorized parties can access it.

Encryption does not of itself prevent interference, but denies the intelligible content to a would-be interceptor.

In an encryption scheme, the intended information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted.

For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm.

It is in principle possible to decrypt the message without possessing the key, but, for a well-designed encryption scheme, considerable computational resources and skills are required.

An authorized recipient can easily decrypt the message with the key provided by the originator to recipients but not to unauthorized users.

Electronic mail, or email, is a method of exchanging digital messages between people using digital devices such as computers and mobile phones.

Email first entered substantial use in the 1960s and by the mid-1970s had taken the form now recognized as email.

Email operates across computer networks, which today is primarily the Internet.

Some early email systems required the author and the recipient to both be online at the same time, in common with instant messaging.

Today's email systems are based on a store-and-forward model.

Email servers accept, forward, deliver, and store messages.

Neither the users nor their computers are required to be online simultaneously; they need to connect only briefly, typically to a mail server or a webmail interface, for as long as it takes to send or receive messages.

Privacy is the ability of an individual or group to seclude themselves, or information about themselves, and thereby express themselves selectively.

The boundaries and content of what is considered private differ among cultures and individuals, but share common themes.

When something is private to a person, it usually means that something is inherently special or sensitive to them.

The domain of privacy partially overlaps security (confidentiality), which can include the concepts of appropriate use, as well as protection of information.

Privacy may also take the form of bodily integrity.

In ecology, sustainability (from sustain and ability) is the property of biological systems to remain diverse and productive .

Long-lived and healthy wetlands and forests are examples of sustainable biological systems.

In more general terms, sustainability is the endurance of systems and processes.

The organizing principle for sustainability is sustainable development, which includes the four interconnected domains: ecology, economics, politics and culture.

Sustainability science is the study of sustainable development and environmental science.
