To complement my recent Java Crypto blog series ("How to get Started Using Java Cryptography Securely", "Cryptographically Secure Pseudo-Random Number Generator (CSPRNG)", "Encryption and Decryption in Java Cryptography", "Message Digests, aka Hashing Functions"), I have been referencing corresponding working code on the GitHub repository. I am happy to announce a brand-new, shiny, modularized,… READ MORE

This is the fourth entry in a blog series on using Java cryptography securely. The first entry provided an overview covering architectural details, using stronger algorithms and debugging tips. The second one covered Cryptographically Secure Pseudo-Random Number Generators. The third entry taught you how to securely configure basic encryption/decryption primitives. This… READ MORE

Skip to the tl;dr This is the second entry in a blog series on using Java cryptography securely. The first entry provided an overview and covered some architectural details, using stronger algorithms and some debugging tips . This entry covers Cryptographically Secure Pseudo-Random Number Generators. This blog series should serve as a one-stop resource for anyone who needs to implement… READ MORE

Skip to the tl;dr Cryptography is the backbone of today's information systems. Its applications are all around us: secure email communications, storage of our login credentials, digital cash and mobile payments, to name just a few. Cryptography is one of the most complicated topics in information security, but the good news is we already have well-defined algorithms, implementations and protocols… READ MORE
