Do you feel cryptographic libraries are just thrown over the fence for us developers and security professionals to understand and pray its used securely? Java Cryptography Architecture is one such famously used the library, laden by ambiguous documentation, over-abundance of algorithmic and key material choices, insecure defaults, and poor architectural choices. All these collectively make it highly probable to make an unfortunate choice and lands us with a flawed cryptographic system. In this session, learn how to securely use each of the Java Cryptography Architecture’s primitives (Random Number Generators, Encryption/Decryption algorithms, HMACs, digital signatures etc.) using real-world code examples to highlight areas that require careful attention and difficult choices. Examine both good and flawed implementations, and learn how to spot mistakes. Then learn how to future-proof the crypto in your applications.

Data encryption and decryption is nothing but just converting a plain text into something that appears to be random and meaningless and vice verse. Generally this encryption is opted by the developers to make the data secured like for password, URL, credit card numbers and so on. If you are using CodeIgniter than to encrypt the data becomes much more easier as compared to native PHP code. As C.I. provides its own encryption class which you can use to encrypt or decrypt the data.

The Java Class Library (JCL) is a set of dynamically loadable libraries that Java applications can call at run time. Because the Java Platform is not dependent on a specific operating system, applications cannot rely on any of the platform-native libraries. Instead, the Java Platform provides a comprehensive set of standard class libraries, containing the functions common to modern operating systems. JCL serves three purposes within the Java Platform: Like other standard code libraries, they provide the programmer a well-known set of useful facilities, such as container classes and regular expression processing. The library provides an abstract interface to tasks that would normally depend heavily on the hardware and operating system, such as network access and file access. Some underlying platforms may not support all of the features a Java application expects. In these cases, the library implementation can either emulate those features or provide a consistent way to check for the presence of a specific feature. java.lang contains fundamental classes and interfaces closely tied to the language and runtime system. I/O and networking access the platform file system, and more generally networks through the java.io, java.nio and java.net packages. For networking, SCTP is available through com.sun.nio.sctp. Mathematics package: java.math provides mathematical expressions and evaluation, as well as arbitrary-precision decimal and integer number datatypes. Collections and Utilities : built-in Collection data structures, and utility classes, for Regular expressions, Concurrency, logging and Data compression. GUI and 2D Graphics: the AWT package (java.awt) basic GUI operations and binds to the underlying native system. It also contains the 2D Graphics API. The Swing package (javax.swing) is built on AWT and provides a platform-independent widget toolkit, as well as a Pluggable look and feel. It also deals with editable and non-editable text components. Sound: interfaces and classes for reading, writing, sequencing, and synthesizing of sound data. Text: java.text deals with text, dates, numbers, and messages. Image package: java.awt.image and javax.imageio provide APIs to write, read, and modify images. XML: SAX, DOM, StAX, XSLT transforms, XPath and various APIs for Web services, as SOAP protocol and JAX-WS. CORBA and RMI APIs, including a built-in ORB Security is provided by java.security and encryption services are provided by javax.crypto. Databases: access to SQL databases via java.sql Access to Scripting engines: The javax.script package gives access to any conforming Scripting language. Applets: java.applet allows applications to be downloaded over a network and run within a guarded sandbox Java Beans: java.beans provides ways to manipulate reusable components. Introspection and reflection: java.lang.Class represents a class, but other classes such as Method and Constructor are available in java.lang.reflect. Keyword list. Like the light makes things visible, keywords make a Java program meaningful. Each term tells us what a part of the program does. abstract boolean break byte case catch class continue default do double else enum extends false final finally float for if implements import int interface long new null package private protected public return short static super switch this throw throws true try void while Common classes. Programs use classes to create complex models and perform various tasks. With keywords we specify and create these classes. Here are some important classes.

Hello Friends, In This Video, I'm Gonna Show You How You Can Encrypt & Decrypt The Hash String With The Help Of Hashlib Python Module Python-Hash-Cracker Program - https://goo.gl/zs3ikD HASHING : - If you need secure hashes or message digest algorithms, then Python’s standard library has you covered in the hashlib module. It includes the FIPS secure hash algorithms SHA1, SHA224, SHA256, SHA384, and SHA512 as well as RSA’s MD5 algorithm. Python also supports the adler32 and crc32 hash functions, but those are in the zlib module. One of the most popular uses of hashes is storing the hash of a password instead of the password itself. Of course, the hash has to be a good one or it can be decrypted. Another popular use case for hashes is to hash a file and then send the file and its hash separately. Then the person receiving the file can run a hash on the file to see if it matches the hash that was sent. If it does, then that means no one has changed the file in transit Cryptographic hashes are used in day-day life like in digital signatures, message authentication codes, manipulation detection, fingerprints, checksums (message integrity check), hash tables, password storage and much more. They are also used in sending messages over a network for security or storing messages in databases. There are many hash functions defined in the “hashlib” library in python. Some of the most used hash functions are: MD5: Message digest algorithm producing a 128 bit hash value. This is widely used to check data integrity. It is not suitable for use in other fields due to the security vulnerabilities of MD5. SHA: Group of algorithms designed by the U.S's NSA that are part of the U.S Federal Information processing standard. These algorithms are used widely in several cryptographic applications. The message length ranges from 160 bits to 512 bits. Functions associated : encode() : Converts the string into bytes to be acceptable by hash function. digest() : Returns the encoded data in byte format. hexdigest() : Returns the encoded data in hexadecimal format. ----------------------------------------------------------------------------------------------------------- Hope This Video Is Helpful For You ► Connect with me! ◄ Facebook - http://bit.ly/2tbOg3b Google+ - http://bit.ly/2jrWz6g Instagram - http://bit.ly/2tbR14z Reddit - https://bit.ly/2J5Vqfm ★★★Watch my most recent videos playlist★★★ Kali Linux - https://goo.gl/36M3JD Deep Web - https://goo.gl/7ueKNh Python Coding - https://goo.gl/dCtyrS Java Coding - https://goo.gl/oxFo8W Basic Computer - https://goo.gl/kwFXM3 Hacking - https://goo.gl/vjT916 Games Benchmark - https://goo.gl/eshw3T Gaming - https://goo.gl/mLuQwf Notepad Tricks -https://goo.gl/3uapMJ CMD Tricks - https://goo.gl/x1KH8C Facebook Tricks - https://goo.gl/1JV9Fz Problem Solved - https://goo.gl/eJwjXq Gmail Tricks - https://goo.gl/fSpbaB And talking about subscribing, please subscribe to my channel, if you enjoyed this video and want more how-to, Thanks so much for watching!

One of Clojure’s strengths is its host interop, but sometimes you really want to call some C code. Perhaps you have a legacy .so/.dll you inherited; perhaps you’re calling a video decoder or some cryptographic routines. This talk focuses on that interop, using a cryptographic library (caesium, which binds libsodium) as a specific example. It shows how Clojure can still leverage its strengths in this context, providing a significantly better environment for both R&D and general use compared to either plain Java or even other high-level C-centric programming environments like Python. This talks includes the mechanics of accomplishing this, lessons learned managing a real library used in production, and future efforts to make this process smoother for future programmers (e.g. manylinux1).

SESSION 2B: Crypto: 01 Mind Your Keys? A Security Evaluation of Java Keystores SUMMARY Cryptography is complex and variegate and requires to combine different algorithms and mechanisms in nontrivial ways. This complexity is often source of vulnerabilities. Secure key management is one of the most critical aspects, since leaking a cryptographic key vanishes any advantage of using cryptography. In this paper we analyze Java keystores, the standard way to manage and securely store keys in Java applications. We consider seven keystore implementations from Oracle JDK and Bouncy Castle, a widespread cryptographic library. We describe, in detail, how the various keystores enforce confidentiality and integrity of the stored keys through password based cryptography and we show that many of the implementations do not adhere to state-of-the-art cryptographic standards. We investigate the resistance to offline attacks and we show that, for non-compliant keystores, brute-forcing can be up to three orders of magnitude faster with respect to the most compliant keystore. Additionally, when an attacker can tamper with the keystore file, some implementations are vulnerable to denial of service attacks or, in the worst case, arbitrary code execution. Finally we discuss the fixes implemented by Oracle and Bouncy Castle developers following our responsible disclosure.

Most developers use cryptography via an application program interface (API) either to a software library or a hardware device where keys are stored and all cryptographic operations take place. Designing such interfaces so that they offer flexible functionality but cannot be abused to reveal keys or secrets has proved to be extremely difficult, with a number of published vulnerabilities in widely-used crypto APIs appearing over the last decade. This lecture will focus on the example of RSA PKCS#11, the most widely used interface for cryptographic devices, but will allow us to develop principles and concepts that apply to most crypto APIs. We will demonstrate a tool, Tookan, which can reverse engineer the particular configuration of PKCS#11 in use on some device under test, construct a model of the device's functionality, and call a model checker to search for attacks. If an attack is found, it can be executed automatically on the device. We will also look at attacks related to the implementation of cryptography. This lecture follows naturally from the general introduction to security APIs, but is independent in the sense that it is disjoint and self-contained. Learning objectives basic design of cryptographic APIs logical flaws in key management cryptographic flaws in implementations The lecture was delivered at SecAppDev 2013 in Leuven, Belgium, by Graham Steel. Graham Steel holds a masters in mathematics from the University of Cambridge and a PhD in informatics from the University of Edinburgh. He is currently a researcher at INRIA, the French national agency for computer science research, where he is part of the Prosecco project team based in central Paris. Steel's main research interests are in formal analysis of information security and applied cryptography. His current work on cryptographic API verification involves using formal techniques to construct and analyse abstract models of cryptographic device interfaces. In addition to international conference and journal publications, his recent results have featured in Wired magazine and the New York Times. He has taught courses on security APIs at Tsinghua University (Beijing) and the University of Venice (Italy) as well as organising a Dagstuhl seminar on the subject.

What exactly is an API? Finally learn for yourself in this helpful video from MuleSoft, the API experts. https://www.mulesoft.com/platform/api The textbook definition goes something like this: “An application programming interface (API) is a set of routines, protocols, and tools for building software applications. An API expresses a software component in terms of its operations, inputs, outputs, and underlying types. An API defines functionalities that are independent of their respective implementations, which allows definitions and implementations to vary without compromising each other. A good API makes it easier to develop a program by providing all the building blocks. APIs often come in the form of a library that includes specifications for routines, data structures, object classes, and variables. In other cases, notably SOAP and REST services, an API is simply a specification of remote calls exposed to the API consumers. An API specification can take many forms, including an International Standard, such as POSIX, vendor documentation, such as the Microsoft Windows API, or the libraries of a programming language, e.g., the Standard Template Library in C++ or the Java APIs. An API differs from an application binary interface (ABI) in that an API is source code-based while an ABI is a binary interface. For instance POSIX is an API, while the Linux Standard Base provides an ABI”. To speak plainly, an API is the messenger that runs and delivers your request to the provider you’re requesting it from, and then delivers the response back to you. To give you a familiar example, think of an API as a waiter in a restaurant. Imagine you’re sitting at the table with a menu of choices to order from, and the kitchen is the provider who will fulfill your order. What’s missing is the critical link to communicate your order to the kitchen and deliver your food back to your table. That’s where the waiter (or API) comes in. ”AHEM” The waiter takes your order, delivers it to the kitchen, and then delivers the food (or response) back to you. (Hopefully without letting your order crash if designed correctly) Now that we’ve whetted your appetite, let’s apply this to a real API example. In keeping with our theme, let’s book a flight to a culinary capital – Paris. You’re probably familiar with the process of searching for airline flights online. Just like at a restaurant, you have a menu of options to choose from ( a dropdown menu in this case). You choose a departure city and date, a return city and date, cabin class, and other variables (like meal or seating, baggage or pet requests) In order to book your flight, you interact with the airline’s website to access the airline’s database to see if any seats are available on those dates, and what the cost might be based on certain variables. But, what if you are not using the airline’s website, which has direct access to the information? What if you are using online travel service that aggregates information from many different airlines? Just like a human interacts with the airline’s website to get that information, an application interacts with the airline’s API. The API is the interface that, like your helpful waiter, runs and and delivers the data from that online travel service to the airline’s systems over the Internet. It also then takes the airline’s response to your request and delivers right back to the online travel service . And through each step of the process it facilitates that interaction between the travel service and the airline’s systems - from seat selection to payment and booking. So now you can see that it’s APIs that make it possible for us all to use travel sites. They interface with with airlines’ APIs to gather information in order to present options back to us The same goes for all interactions between applications, data and devices - they all have API’s that allow computers to operate them, and that's what ultimately creates connectivity. API’s provide a standard way of accessing any application, data or device whether it is shopping from your phone, or accessing cloud applications at work. So, whenever you think of an API, just think of it as your waiter running back and forth between applications, databases and devices to deliver data and create the connectivity that puts the world at our fingertips. And whenever you think of creating an API, think MuleSoft.
