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

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.

jSignature - jQuery plugin for adding web signature functionality

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.

PDF Little Signer

PDF Little Signer is a .NET3.5 library for self signing PDF document. It's very easy to use. It uses iTextSharp.


iSafePDF is a PDF protection software. it allows you to encrypt PDF document, signe them using a certificate and timestamp the signature. all those features are PDF standards so your document will be readable/editable with all standard PDF programs.

sigmund - Quick and dirty psychoanalysis for objects

Quick and dirty signatures for Objects.This is like a much faster deepEquals comparison, which returns a string key suitable for caches and the like.

git-secure-tag - Secure git tag signing

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)

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.

sphincs - Erlang NIF for SPHINCS-256: practical stateless hash-based signatures.
