...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.

...The secret message is an 1-bit deep black & white image. The message can contain written text, a drawing, a secret code etc. Using Visual Cryptography the application splits the secret message into two "shadow images" called <<shares>>. Any of the two shares will be embedded into a "normal" image file called by tradition <<vessel>>. You can use a method of hand to send the two vessels to your correspondent. For instance you can post one vessel image on facebook. The other vessel image can be sent as an attachment of an e-mail. The vessel images can be 8-bit gray-level images or 24-bit deep true-color images.

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.

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.

...Analyzing a single share, no one will be able to obtain any information considering the secret image no matter the computing or the analyzing power. In an Extended Visual Cryptography Scheme, both the secret image and the shares are meaningful images like a landscape, a building or a beautiful girl, hiding the very intention to conceal a secret. PyEvcs is a command line Python application allowing you to experiment with Extended Visual Cryptography Schemes for "natural" continuous tone images.

A tool to hide a file into a image with no affects the size. It uses a steganography techinique that change the least significant bit in the RGB color systems of non compressed images to store the bits of the file to hide.

stegotools is a suite of UNIX command-line applications to read/write hidden information from/in files using steganography. It currently fully supports 24bpp bitmap images.

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.

Boot Integrity Services (BIS) is a CDSA application. BIS adds digital signatures to boot images obtained via PXE and DHCP/BOOTP protocols. BIS includes tools for creating keys, certificates, and digital signatures, and remotely configuring BIS clients.

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
