Open Source Java Cryptography Software - Page 9

This tool checks the integrity of files. It is very important if you don’t want your computer to get infected with viruses and malware. Sometimes, hackers and malicious software developers modify the contents of a downloadable zip, which can even result in granting them remote access to your system. While downloading various software, you might have noticed that developers usually provide hash values (MD5) of their files. This tool enables you to verify the file integrity of the downloaded content. I have tried to keep the file size to a minimum. And currently, the file size is 20.7 kB (20,701 bytes). Anyone can inspect the source code and use it to modify, develop and redistribute.

JChecksum allows you to obtain the hash of a given file using a simple GUI. Hash algorithms supported include MD2, MD5, SHA-1, SHA-256, SHA-384, and SHA-512.

JConfigura is a library usable in java environments for sharing configuration parameters between different java applications. Moreover it exculpates developers of aspects like property file reading and securing property files with rsa encryption.

JCryptor uses the Caesar-cipher to encrypt keystrokes on-the-fly. It can also be used to decrypt an encrypted text easily. Caesar-cipher is a simple encryption algorithm, developed by Julius Caesar, to encrypt his correspondence with Cicero in the ancient world. Therefore it uses a simple character substitution method to replace a given character by another. A keyshift of thirteen is called ROT13. ROT13 can be decrypted by encrypting it again with ROT13. Even today this simple method is used by authorities to protect documents from unintentional reading. --UPDATE-- [25.01.14] Release 1.0 (final) -- Bugfixes [05.05.12] Release 0.2 -- implements polyalphabeticel substitution

JEasyCrypt library is developing to do your live easy and trust with cryptographic and else security things inside your java software.

JFish is a simple Java implementation of the popular Twofish cryptography algorithm. It allows any application to easily implement powerful encryption, using a single small library and minimal code changes.

JMixNet is a Java implementation of a so called Chauminian Mixnet (or mix-net, or even mix net, at your will ;). It is an anonymous communication network, designed to provide anonymity in data transfers among Internet users.

Suite of services and tools for handling PKI requirements. The initial list of programs contains: 1) a viewer/encoding converter for X.509 certificates, 2) a viewer/editor/generator for PKCS#7 and 3) a viewer/editor/generator for various keystores types.

A java application that allows you to store files into a "data store". These files are encrypted by passphrases and padded with random garbage to provide plausible deniability (you cannot know if there are any more files in the store or not).

JRijndael is a 100% pure Java implementation of the popular Rijndael (aka AES) cryptography algorithm. It's designed to be implemented as easily as possible and features ECB, padding, and a simple API.

Jssltrace is a java-based tool, which enables it's user to intercept ssl based communication between two programs. Jssltrace works essentiallly in the same manner as tcptrace (http://www.pocketsoap.com/tcptrace), which is the main inspiration for it.

JSerpent is an easy to use Java implementation of the powerful Serpent cryptography algorithm. It can be easily implemented into any project, and is complete with ECB, padding, and a simple API.

A Java program to encrypt files and make them relatively safe for transfers across networks. Currently just in commandline form, but an application is in the works.

The aim of this project is to create a set of basic java tools for developers who need Certificate Authority (CA) root certificates and user certificates signed by the CA.

Java Stacked Crypto merges different hiding, merging and crypto stacks to secure files.

Java project. A java application that creates jars with encrypted content inside. With a selfextract and decrypt built in. GUI aswell as console functionallity. Options to include a key salt inside of the jar to hinder bruteforce attempts.

The project Jaulp is jet another utility library project written in Java. It contains utility classes for Date ,Calendar, Collections, Resources, Files, IO for Random data, and many more. This is the last version for this project.

Java Crypt Framework (JCryptFX) is a java-based education project for de-/encrypting streams. It has a implementation of DES and TripleDES in it but the framework user can write own cryptography algorithms and stream types for it - includes a console app

JCEF (Java Cryptographic Extension Framework) is an API that facilitates enormously the use of the cryptographic architecture of Java

A JNI wrapper for the Microsoft Data Protection API

I have packaged the Java encryption library with a wrapper used to make saving and loading files in Java easier. I have also included the source for a command line application to encrypt a String and save it to a text file. The source for AESEncryption was actually written by "erickson" from Stack Overflow. The original post can be found here: http://stackoverflow.com/questions/992019/java-256-bit-aes-password-based-encryption/992413#992413

A pure java library to operate on OpenPGP cards directly using javax.smartcard apis with no need of external dlls/frameworks (such as pkcs11 or opensc-java). Includes sample OpenPGP card edit application.
