Breaking misused stream ciphers
Encryption algorithms can be classified in a couple of different ways. A top-level distinction is between symmetric encryption algorithms (which use the same...
Cryptography
Entropy calculations
Entropy is a measure of the randomness in a system. The more random the system, the less predictable it is and the higher its entropy.
Entropy is useful...
Blockchain and asymmetric cryptography
Blockchain technology makes it possible to solve business problems in ways that were previously impossible. A major enabler of this is the decentralization...
Security of the PKI ecosystem
Public Key Infrastructure (PKI) is the backbone of trust for many systems on the Internet. One of the most common uses of PKI is the HTTPS protocol, which...
Elliptic curve cryptography
As its name suggests, elliptic curve cryptography (ECC) uses elliptic curves (like the one shown below) to build cryptographic algorithms. Because of the...
Methods for attacking full disk encryption
Full disk encryption is part of cryptography that uses mathematical structures and operators. Cryptography and cryptanalysis functions are used in modern software...
Introduction to Public Key Infrastructure (PKI)
Public Key Infrastructure (PKI) uses mathematical structures and operators. Cryptography and cryptanalysis functions are used in modern software development....
Introduction to the TLS/SSL cryptography protocol
SSL stands for Secure Socket Layer. First version of SSL was developed by Netscape in 1995. SSL is the industry standard to establish secure internet connection...
Introduction to Diffie-Hellman Key Exchange
Encryption is the process of converting plaintext to encrypted text. Since encrypted text cannot be read by anyone, encrypted text hides the original data from...
Introduction to the Rivest-Shamir-Adleman (RSA) encryption algorithm
Encryption is the process of converting plaintext to encrypted text. Since encrypted text cannot be read by anyone, encrypted text hides the original data from...
