This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Ideally, only authorized parties can decipher a ciphertext back to plaintext and access the original information.

WebbFrom there, the second post describes some of the historical cryptographic milestones of the 20th century: the Enigma machine, the Data Encryption Standard (DES), and the invention of asymmetric encryption. In this post, we will explore how cryptography has evolved in the 21st century.
Cryptography, the use of codes and ciphers to protect secrets, began thousands of years ago. Until recent decades, it has been the story of what might be called classical cryptography — that is, of methods of encryption that use pen and paper, or perhaps simple mechanical aids. In the early 20th century, the invention of … Visa mer The earliest known use of cryptography is found in non-standard hieroglyphs carved into the wall of a tomb from the Old Kingdom of Egypt circa 1900 BC. These are not thought to be serious attempts at secret … Visa mer Although cryptography has a long and complex history, it wasn't until the 19th century that it developed anything more than ad hoc approaches to either encryption or cryptanalysis (the science of finding weaknesses in crypto systems). Examples of the … Visa mer Encryption in modern times is achieved by using algorithms that have a key to encrypt and decrypt information.
