In the digital era, the goal of cryptography remains the same: to prevent information exchanged between two parties being swiped by an adversary. Computer scientists often refer to the two parties as “Alice and Bob,” fictional entities first introduced in a 1978 article describing a digital en...
The word comes from the Greek word "kryptos," meaning 'secret' or 'hidden.' The literal translation for cryptography is "secret writing." It comes from the study of cryptology, the art of breaking codes or ancient hieroglyphics and solving them. Data encryption is one of the most important...
Elliptic Curve Cryptography or ECC Encryption: A newer encryption algorithm that provides enhanced security with shorter key lengths than RSA. Because it needs less processing power, ECC is ideal for mobile apps, cryptocurrency transactions, and internet messaging. Advantages of Encryption Encryption pro...
Cryptography is the process of hiding or coding information so only the intended recipient can read a message. Discover how cryptography works and the potential risks it poses.
Learn about cryptography, the process of encoding data, including types of cryptography, current algorithms, challenges, and types of algorithms used in the process.
With symmetric cryptography, the same key is used for both encryption and decryption. A sender and a recipient must already have a shared key that is known to both. Key distribution is a tricky problem and was the impetus for developing asymmetric cryptography. ...
A widely used form of public key cryptography, called RSA encryption, taps into the tricky nature of prime factorization – finding two prime numbers that multiply together to give you a specific solution. Multiplying two prime numbers takes no time at all, but even the fastest computers on Ear...
Cryptography vs encryption The difference between cryptography and encryption is that while cryptography can be broadly defined as the science of sending secret messages, encryption is the specific process of converting data into code. While encryption is an integral part of cryptography, it is just ...
Cryptography is the process of ensuring that messages can only be interpreted by the intended recipient. Core techniques involve encryption (converting plaintext to ciphertext) and decryption (reverting ciphertext to plaintext) using keys. There are various types of cryptographic techniques, including ...
Cryptography is the practice of developing and using coded algorithms to protect and obscure transmitted information.
