Encryption is one of the pillars of modern-day communications. You have devices that use encryption all the time, even if you are not aware of it. There are so many applications and systems using it ...

In the context of cryptography, a public key is an alphanumeric string that serves as an essential component of asymmetric encryption algorithms. It is typically derived from a private key, which must ...

A private key, also known as a secret key, is a cryptographic key that is used to decrypt or digitally sign data. It is a crucial component in asymmetric encryption algorithms like RSA and ECC ...

An encryption method for transmitting data that uses key pairs, comprising one private and one public key. Public key cryptography is called "asymmetric encryption" because both keys are not equal. A ...

Encryption systems used by businesses fall into two broad categories. Private key, or secret key, systems use the same key to encrypt and decrypt data, so you need to keep your key hidden so that no ...

For thousands of years, if you wanted to send a secret message, there was basically one way to do it. You’d scramble the message using a special rule, known only to you and your intended audience.

The original version of this story appeared in Quanta Magazine. For thousands of years, if you wanted to send a secret message, there was basically one way to do it. You’d scramble the message using a ...

A large random number that is used in a two-part cryptographic system such as RSA. The private key is used to create its public key counterpart, and although the private key is kept hidden, the public ...

Public key authentication with SSH is possible with WinSCP, but it requires some work to set up. Chad Perrin details the steps. WinSCP is an open source tool for ...
