    xxHash

    xxHash

    Extremely fast non-cryptographic hash algorithm

    xxHash is an extremely fast non-cryptographic hash algorithm, working at RAM speed limit. It is proposed in four flavors (XXH32, XXH64, XXH3_64bits and XXH3_128bits). The latest variant, XXH3, offers improved performance across the board, especially on small data. It successfully completes the SMHasher test suite which evaluates collision, dispersion and randomness qualities of hash functions. Code is highly portable, and hashes are identical across all platforms (little / big endian). Performance on large data is only one part of the picture. Hashing is also very useful in constructions like hash tables and bloom filters. In these use cases, it's frequent to hash a lot of small data (starting at a few bytes). Algorithm's performance can be very different for such scenarios, since parts of the algorithm, such as initialization or finalization, become fixed cost. The impact of branch misprediction also becomes much more present.

    shadowsocks-libev

    shadowsocks-libev

    Bug-fix-only libev port of shadowsocks

    Shadowsocks-libev is a lightweight secured SOCKS5 proxy for embedded devices and low-end boxes. Shadowsocks-libev is written in pure C and depends on libev. It's designed to be a lightweight implementation of shadowsocks protocol, in order to keep the resource usage as low as possible. Snap is the recommended way to install the latest binaries. You can build shadowsocks-libev and all its dependencies by script. The latest shadowsocks-libev has provided a redir mode. You can configure your Linux-based box or router to proxy all TCP traffic transparently, which is handy if you use an OpenWRT-powered router. Although shadowsocks-libev can handle thousands of concurrent connections nicely, we still recommend setting up your server's firewall rules to limit connections from each user. We strongly encourage you to install shadowsocks-libev from jessie-backports-sloppy.

    AWS Encryption SDK for C

    AWS Encryption SDK for C

    AWS Encryption SDK for C

    The AWS Encryption SDK for C is a client-side encryption library designed to make it easy for everyone to encrypt and decrypt data using industry standards and best practices. It uses a data format compatible with the AWS Encryption SDKs in other languages. For more information on the AWS Encryption SDKs in all languages, see the Developer Guide. We will demonstrate some simple build recipes for Linux, Mac, and Windows operating systems. These recipes assume a newly installed system with default installs of dependency packages. The Windows instructions install everything in your current directory (where you run the build process). The AWS Encryption SDK for C can be used with AWS KMS, but it is not required. For best results when doing a build with AWS KMS integration, do not install aws-c-common directly. Build and install the AWS SDK for C++, which will build and install aws-c-common for you (see the C++ SDK dependencies here).

    BTCore

    A Collection of Useful Java/Swing Code

    NEWEST FEATURE ---------- Added one line ".zip" extraction to Util class! Added one line ".zip" extraction from URL (web) and one line file download from URL! BTCore is a library that was designed to be used with all of Banotech's software. It includes a tremendous amount of code snippets and classes that have been boiled down to allow ease of use by everyone. BTCore is, and always will be FREE. It has tools that we scrapped together over our last few projects, and that we found were hard to implicate. So what we did was boil them down for your ease of use. Not everything is super glamorous, and there is nothing in this library you cant already do yourself, the idea is simply to take one thing out of your hands, so that you can focus on coding the important stuff. See features for some examples of code you'll find in BTCore.

    DAL4j

    Data Access Layer 4 Java

    Welcome to Data Access Layer for Java (DAL4j) a set of command line tools and framework used to reverse engineer a MySQL or SQLServer database schema into a set of JPA Entity Beans. DAL4j can be useful for scenarios where there is an existing database schema but a technology other that JPA is used to interact with the database. DAL4j can provide an easy way to migrate your code base from other technologies such as JDBC or Hibernate to JPA. The beans generated can be 1 or two types: Simple or Framework. Simple beans are standard pojo classes managed by your application using JPA semantics. Framework generated pojos use the DAL4j framework DAO generic to simplify CRUD operations. DAL4j provides optional hooks to allow you to integrate encryption/decryption of data field used when data is encrypted in the database. Last, DAL4j provides a set of Generic classes that can be used to simplify creation of J2E Session Beans which perform CRUD operations using generated Entities

    Keybase client

    Keybase Go library, client, service, OS X, iOS, Android, Electron

    Keybase is secure messaging and file-sharing. We use public key cryptography to ensure your messages stay private. Even we can’t read your chats. Keybase works for families, roommates, clubs, and groups of friends, too. Keybase connects to public identities, too. You can connect with communities from Twitter, Reddit, and elsewhere. Don’t live dangerously when it comes to documents. Keybase can store your group’s photos, videos, and documents with end-to-end encryption. You can set a timer on your most sensitive messages. This distribution includes cryptographic software. The country in which you currently reside may have restrictions on the import, possession, use, and/or re-export to another country, of encryption software. BEFORE using any encryption software, please check your country's laws, regulations and policies concerning the import, possession, or use, and re-export of encryption software.
