These articles explain the algorithms for performing encryption and decryption in cryptography.
With quantum computers getting more powerful each year, many worry about the safety of modern encryption standards. As quantum computers improve in performance and the number of qubits used for calculations increases, current cryptosystems are under threat. AES-256 is one of the most powerful symmetric ciphers, but will it remain secure in a post-quantum world? … Read more
Need to encrypt some text with a password or private key in Python? AES-256 is a solid symmetric cipher that is commonly used to encrypt data for oneself. In other words, the same person who is encrypting the data is typically decrypting it as well (think password manager). Dependencies For this tutorial, we will be … Read more
If you are getting into cryptography, or just trying to understand the fundamentals, you may have noticed that the exclusive-or (XOR) operation is used quite often, especially in ciphers. XOR is a simple bitwise operation that allows cryptographers to create strong encryption systems, and consequently is a fundamental building block of practically all modern ciphers. … Read more
AES stands for “Advanced Encryption Standard” and is a specification that has selected the Rijndael cipher as its symmetric key ciphering algorithm. AES encrypts a message with a private key and no one except the key holder can decrypt the message. This is useful for many reasons, but a good example is a laptop that … Read more
Qvault’s dual encryption allows users to require that two keys are needed to unlock their vault. A password, and a key card. You have probably heard of two factor authentication. According to Authy: 2FA is an extra layer of security used to make sure that people trying to gain access to an online account are who they … Read more
