...It provides a graphical desktop interface for everyday users and a command-line mode for scripted and server-side workflows. Supported capabilities include PKCS#12 keystores, smartcards and hardware tokens (PKCS#11), Windows keystore integration, visible signatures with custom images and positioning, timestamp authority (TSA) support, OCSP/CRL revocation checks, certification signatures, and PDF encryption. Cross-platform (Windows, Linux, macOS), built on the OpenPDF library, and translated into many languages by its community, JSignPdf is a trusted choice for anyone who needs reliable PDF signing without commercial licensing.

bin64ed is a binary base64 encoder/decoder that allows you to encode/decode binary files (such as images, pdfs, etc) to and from base64.

A library written in Visual C# for encrypting a text message into an image file, and decrypting an image file to get the text message using Rijndael Algorithm, RSA Algorithm, and LSB Substitution Algorithm.

This is a steganogric program that uses images last bits to hide information ( files ). It can crypt data with a rotation and a xor key.

I'm using an MD5 hash of a username and password field to generate some entropy which is used to generate color pallets and positions / scaling of two Mandelbrot sets. These two images are overlaid to create interesting pictures which represent the entered credentials. I'm interested in all things security, this is mostly just for fun, but could possibly be used to help users identify mistakes in their password entry prior to submission and enforce a tighter failed password lockout policy. Please enjoy with a modern HTML5 enabled browser.

This project provides a steganography tool that allows to know, use and compare the results of current steganographic techniques. It also incorporates a comprehensive set of stegoanalitics methods for images.

LSB Steganography tool which provides hide ASCII infomation within 24-bit Bitmap images

Embeds text and files in images with optional encryption. Easy-to-use UI, error reporting, and self-update (beta)

A suite of multiple cryptography related tools for encryption and steganography (images and audio); it focuses on the use of non-popular/new, symmetric algorithms.

The Watermarks is a java library for images and text watermarking fingerprinting and tamper-proofing. The supported carrier formats for a watermark are JPEG and PDF. The project also aim to build a test environment to evaluate robustness of implemented a
