PiracyChecker - An Android library that prevents your app from being pirated / cracked using Google Play Licensing (LVL), APK signature protection and more

Java

An Android library that prevents your app from being pirated / cracked using Google Play Licensing (LVL), APK signature protection and more. This library applies some techniques to help protect your app's users and attempt to thwart reverse engineers and attackers. BUT, this isn't guaranteed to stop your app from getting pirated. There is no such thing as 100% security, and a determined and skilled attacker with enough time, could remove these checks from the code. The real objective here is to raise the bar out of reach of opportunist and automatic attackers.

tweetnacl-js - Port of TweetNaCl cryptographic library to JavaScript

Javascript

Port of TweetNaCl / NaCl to JavaScript for modern browsers and Node.js. Public domain.The primary goal of this project is to produce a translation of TweetNaCl to JavaScript which is as close as possible to the original C implementation, plus a thin layer of idiomatic high-level API on top of it.

jSignature - jQuery plugin for adding web signature functionality

Javascript

jSignature is a jQuery plugin which simplifies creation of a signature capture field in the browser window, allowing a user to draw a signature using mouse, pen, or finger. jSignature captures signature as vector outlines of the strokes. Although jSignature can export great bitmap (PNG) too, extraction of highly scalable stroke movement coordinates (aka vector image) of the signature allows much greater flexibility of signature rendering.

FLIRTDB - A community driven collection of IDA FLIRT signature files

Fast Library Identification and Recognition Technology, also known as FLIRT, is IDA's internal symbols identifier that searches through disassembled binaries in order to locate, rename, and highlight known library subroutines. FLIRT elimates the need to analyze functions that could be understood simply by reading documentation or source code from the library it came from and reduces the amount of work required in order to reverse and understand symbol-stripped binaries by a considerable amount. The input to the system is a library file (.lib on Windows) from a library of choice while the output is a signature file (.sig) stored under /sig (and only there or else IDA won't find it). Using one of the tools (plb/pcf/pelf) (provided here for paying customers) you convert all the functions in the library to signatures stored in a PAT file (.pat). The final stage in creating a signature file involves converting the generated PAT file into a .sig file usable by IDA with the use of sigmake. The problem with this is that sometimes collisions will exist for signatures since the method Hex-Rays uses is not fool proof. When an error occurs an EXC (.exc) file is created. In order to ignore collisions, simply edit this file by removing the first few comments (lines that start with ';') and re-run sigmake.

git-secure-tag - Secure git tag signing

Javascript

git uses SHA-1 hashes when signing tag. SHA-1 is generally deprecated and is not a collision-safe anymore (though, collisions are yet to come pre-image attack is yet to come).git-secure-tag runs cat-file recursively for each entry (sorted alphabetically), enters submodules (if present), and hashes file/directory names, file contents, and submodules (recursively again) into a resulting Git-EVTag-v0-SHA512: ... SHA512 digest.

sirp - Secure (interoperable) Remote Password Auth (SRP-6a)

Ruby

This is a pure Ruby implementation of the Secure Remote Password protocol (SRP-6a), which is a 'zero-knowledge' mutual authentication system. SRP is an protocol that allows for mutual authentication of a client and server over an insecure network connection without revealing the password to the server or an eavesdropper. If the client lacks the user's password, or the server lacks the proper verification key, the authentication will fail. This approach is much more secure than the vast majority of authentication systems in common use since the password is never sent over the wire. The password is impossible to intercept, or to be revealed in a server breach, unless the verifier can be reversed. Since the verifier is derived from the password + salt through cryptographic one-way hash functions and Modular Exponentiation. Attacking the verifier to retrieve a password would be of similar difficulty as deriving a private encryption key from its public key. Extremely difficult, if not impossible.
