How to create your own crappy RSA as a software developer

Introduction One of the key developments in cryptography was the introduction of public key (or asymmetric) cryptosystems. These rely on pairs of keys: one of them is the public key (known to everybody) and the other is the private key (known only to the specific user). The public key is

Math Survival Kit for Developers

Introduction When working with cryptographic applications you need to understand some of the underlying math (at least, if you want to do things properly). For example, the RSA cryptographic system (which was one of the earliest methods and most widely adopted, until it lost ground to better methods, such as

elliptic curves

Need for speed: Elliptic curves chapter

Introduction Elliptic curves (EC) have gained widespread acceptance as tools for cryptography. They offer several advantages over other methods, such as RSA, providing equal levels of security with shorter keys (for example, 228-bit keys in EC cryptography are as good as 2300-bit RSA keys). This represents an advantage, since more

cryptography

What every developer needs to know about elliptic curves

Elliptic curves (EC) have become one of the most useful tools for modern cryptography. They were proposed in the 1980s and became widespread used after 2004. Its main advantage is that it offers smaller key sizes to attain the same level of security of other methods, resulting in smaller storage

Ethereum development made easy with Foundry

As part of our trip to Devcon Amsterdam back in April, we attended the War Room Games Amsterdam competition, an Ethereum CTF where you "hacked" smart contracts to win points. The event was loads of fun, but we realized while playing that our main obstacle was not Ethereum/

Secure computation in Rust: Using Intel's SGX instructions with Teaclave and Fortanix

TEEs can be thought of as processes that are running "isolated" from the OS and upper layers in a secure part of the CPU. The idea of this is to help to significantly reduce the attack surface.
