This is an android application able to perform AES-128 bit encryption on all types of files. Its tested encryption speed for 1080 HD video on android device is 3.43 MB per second, and decryption speed is 6.25 MB per second for android device with 3 GB RAM and MT6735 Quad-core 1.3 GHz CPU.

The GPGUI program is GUI wrapping GnuPG functionality provided by Bouncy Castle. The program allows you to encrypt/sign/decrypt text messages and files using asymmeric PGP keys. The program can read and manage GnuPG keys if GnuPG is installed. But the program also maintains its own secret and public key files and having GnuPG installed is optional.

Hash is fast and simple java utility program for calculating and verifying checksums for files and text. Hash can generate MD5, SHA-1, SHA-256, SHA-384 and SHA-512 checksum values.

An open source Java/Java Card implementation of the ISO7816 and related PKI standards.

Encryption/Decryption demonstration app using the S-DES algorithm. Use the Java runtime environment 11 for execution. The GUI pops up that allows entering a 10-bit encryption/decryption key in binary (0, 1 digits) and the plaintext/ciphertext in the same form (8-bit). Executing the algorithm, decription of the encoding/decoding functionality is provided in the three main text boxes.

StrongKey PKI2FIDO is a web application written in Angular and Java using REST web service calls for client-server communication. The application enables users that have X.509 digital certificates (optionally, on smart cards—such as the PIV card or CAC) to strongly authenticate to PKI2FIDO using TLS ClientAuth and then register a FIDO Security key with a FIDO Server (such as StrongKey FIDO Server at https://sourceforge.net/projects/strongkeyfido/). The TLS ClientAuth strong authentication process validates the digital certificate's chain (if any) and uses CRLs to verify the certificate's revocation status (OCSP checking will come in the next release). Once the certificate chain is validated, it checks an LDAP server to determine if the user is authorized to register a FIDO Security key with the site. Since PKI2FIDO is a sample application, a De-register button is enabled to delete FIDO keys; This enables the user to keep testing with the same username.

Tristero is a framework for creating distributed peer-to-peer file sharing applications. It uses standard technologies for each component, reducing the work of implementing a particular network architecture to the novel aspects of that system and eliminat

mystic-crypt is designed as a Java library that can be used for simple and complex encryption and decryption. The source code for the library is available under https://github.com/astrapi69/mystic-crypt For demonstration what the library can do there is a graphical client: The source code for the ui is available under https://github.com/astrapi69/mystic-crypt-ui

Java library with Cryptographic algorithms. Easy to use Crypto algorithms. Works on Windows, Linux, Android. No external lib dependencies, no useless abstractions, no 'crypto provider'. Elliptic curves was borrowed from BouncyCastle and simplified a lot. Most of EC classes are custom algorithms for certain curves. Can be easily deleted if u dont need them. With couple of classes u can parse and construct those ugly ASN.1 structures, look at RSA and EC key formats for example. No bad dependencies between classes, so u can easily cut off unnecessary code and simply include what u need in your project. Feel free and simple without headache. We are using class Binary as best for us to work with byte arrays. Simple classes for console-like colored apps in GUI-mode. Look also http://demo.sls.team

Composed of a Java steganographic library and GUI to use steganography. Primarily intended for research communities on security and steganography to implement new dissimulation and steganalysis algorithms. More information at www.hidereveal.org

Crack the encrypted passwords (MD5,SHA, etc....)

Bork is a very small, cross-platform file encryption utility. It is written in Java and designed to be included along with the files it encrypts for long-term storage (eg on CD-R). Its minimal external dependencies make it fairly futureproof.

Certificate-helper is a utility desktop application written in Java designed and created to assist (mainly developers) in creating and viewing keystores and digital certificates. This is done via a user interfaces implemented in Swing.

Cryptomni is a program which can encrypt and decrypt files using the one-time pad cipher. If a key is truly random, kept secret, and never reused, this encryption algorithm can be proven to be unbreakable.

DKIM for JavaMail is a small JAR that can be easily implemented in existing Java projects using JavaMail for sending DKIM signed emails.

Encrypti is a multi platform, easy to use encrypting tool for keeping your files secure. This application offers portability of encrypted files between various platforms. Secure your files with Encrypti!

Ganzúa is a cryptanalysis tool for classical ciphers (mono and polyalphabetic) that lets the user define almost completely arbitrary cipher and plain alphabets, allowing for the proper cryptanalysis of cryptograms obtained from non-English texts.

This java tools design to decrypt and obtain the MS Windows Admin password from encrypted password get from Amazon EC2. It can run as standalone application or embedded as Java applet in HTML.

HashSum is a .NET port from GNU's md5sum and sha1sum. It supports: hash algorithm selection between MD5 and SHA1 (more could be added later) and compatibility between HashSum and GNU's checksum file format
