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 ...

What are cryptographic keys, and why should they be kept safe? A cryptographic key is a string of data that is used to encrypt data (to the data secret), decrypt data (to perform the reverse operation ...

Scientists at Northwestern University say they have harnessed the properties of light to encrypt information into code that can be cracked only one way: by breaking the physical laws of nature. This ...

Cryptography puts the “crypto” in cryptocurrency. It has existed much longer than our digital age and has evolved like languages over the centuries. One of the most famous uses was developed by Julius ...
