Cryptography is the art of encrypting and decrypting data. Encryption is the process of encoding unencrypted data, or plaintext, into encrypted data, or ciphertext, to disguise the data and make it ...

In cryptography, an encryption key is a variable value that is applied using an algorithm to a string or block of unencrypted text to produce encrypted text or to decrypt encrypted text. The length of ...

Nathan Eddy works as an independent filmmaker and journalist based in Berlin, specializing in architecture, business technology and healthcare IT. He is a graduate of Northwestern University’s Medill ...

Understand the crypto concepts behind the modern internet security infrastructure, from digital signatures and transport layer security to blockchains and Bitcoin. Cryptography grows ever more ...

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 ...

The Internet is one of the most important inventions in human history. It has changed our lives for the better, and it’s now an integral part of our society. We can’t go back to a world without it.

Every time you send a text, pay for groceries with your phone, or use your health site, you are relying on encryption. It’s an invisible shield that protects your data from prying eyes. Encryption is ...

The Diffie-Hellman algorithm was a stunning breakthrough in cryptography that showed cryptographic keys could be securely exchanged in plain sight. Here’s how it works. Whitfield Diffie and Martin ...

Typically asymmetric keys are used to encrypt symmetric keys. It's a lot faster to decode using something like AES, than encrypting very large binaries with asymmetric keys. The idea is the AES key ...
