Video: Common Crypto Mistakes in Android
About: If you do a web search for “encrypting Strings in Android”, you’ll find a lot of example code, and they all look pretty similar. They definitely input a String and output gibberish that looks like encrypted text, but they are often incorrect.
In this talk, we’ll discuss the use of a very common crypto algorithm, AES, and show how code examples on the Internet usually make serious mistakes in how they use AES libraries. What are the consequences of these mistakes and what are more reasonable defaults. We’ll also talk a bit about our simple Android librarythat tries to do AES right.
