JSignPdf is a free, open-source Java application for signing PDF documents with digital certificates. 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.

FreeArc combines best 7-zip and RAR features: auto-selected LZMA/PPMD/Multimedia compression, 1gb dictionary, exe/dict/delta data filters, updatable solid archives, SFXes, recovery record, AES+Twofish+Serpent encryption, Linux support and much more...

Portecle is a user friendly GUI application for creating, managing and examining key stores, keys, certificates, certificate requests, certificate revocation lists and more.

X Certificate and Key management is an interface for managing asymetric keys like RSA or DSA. It is intended as a small CA for creation and signing certificates. It uses the OpenSSL library for the cryptographic operations. Please see the XCA homepage http://hohnstaedt.de/xca

DAR is a command-line backup and archiving tool that uses selective compression (not compressing already compressed files), strong encryption, may split an archive in different files of given size and provides on-fly hashing, supports differential backup with or without binary delta, ftp and sftp protocols to remote cloud storage Archive internal's catalog, allows very quick restoration even a single file from a huge, eventually sliced, compressed, encrypted archive eventually located on a remote cloud storage, by only reading/fetching the necessary data to perform the operation. Dar saves *all* UNIX inode types, takes care of hard links, sparse files as well as Extended Attributes (MacOS X file forks, Linux ACL, SELinux tags, user attributes) and some Filesystem Specific Attributes (Linux ext2/3/4, Mac OS X HFS+) more details at: http://dar.linux.free.fr/doc/Features.html

EJBCA is an enterprise class PKI Certificate Authority built on JEE technology. It is a robust, high performance, platform independent, flexible, and component based CA to be used standalone or integrated in other JEE applications.

This project is an implementation of the TCG TPM 2.0 specification. It is based on the TPM specification Parts 3 and 4 source code donated by Microsoft, with additional files to complete the implementation. See the wiki for additional support - additions to the documentation. See the companion IBM TSS at https://sourceforge.net/projects/ibmtpm20tss/

ccrypt is a command-line tool for encrypting and decrypting files and streams. It provides strong encryption based on the Rijndael cipher, a version of which is also used in the Advanced Encryption Standard.

AirSnort is a wireless LAN (WLAN) tool which cracks encryption keys on 802.11b WEP networks. AirSnort operates by passively monitoring transmissions, computing the encryption key when enough packets have been gathered.

BeeCrypt is an ongoing project to provide a strong and fast cryptography toolkit. Includes entropy sources, random generators, block ciphers, hash functions, message authentication codes, multiprecision integer routines, and public key primitives.

Duply is a shell front end for the duplicity backup tool https://duplicity.us . It simplifies the usage by implementing backup job profiles, batch commands and more. Secure backup to non-trusted file spaces made easy.

Portable PGP is a fully featured lightweight java based PGP tool. It allows to encrypt,decrypt,sign and verify text and files with a nice and absolutely straight graphical interface.

Msieve is a C library implementing a suite of algorithms to factor large integers. It contains an implementation of the SIQS and GNFS algorithms; the latter has helped complete some of the largest public factorizations known

The OpenSC project allows the use of PKCS #15 compatible SmartCards and other cryptographic tokens (e.g. the Aladdin eToken) in UNIX compatible operating systems. OpenSC can use PC/SC Lite or CT-API as its reader backend. https://github.com/OpenSC/OpenSC/wiki/OpenSC-Services

Keytool is an Eclipse plugin that maintains keystores and certificates. It allows you to create certificates and put them in a keystore. You can from Eclipse, open and inspect certificates that are stored as .cer, or in a given keystore.

Crypto++ is a free C++ class library of cryptographic schemes originally written by Wei Dai. The library is now maintained by a community of volunteers. The Crypto++ website is located at https://cryptopp.com/, and the source code is located at https://github.com/weidai11/cryptopp. The repository was moved in response to developer requests for Git access. The SourceForge site will remain in "read only" mode for historical purposes. You should visit the Crypto++ website at https://cryptopp.com/ or GitHub at https://github.com/weidai11/cryptopp to view the latest news, download the latest source code, file bugs and request features. We thank SourceForge for hosting us through the years.

The database access library for C++ programmers that provides the illusion of embedding SQL in regular C++ code, staying entirely within the C++ standard.

This ASN.1 compiler turns ASN.1 specifications into C code. The asn1c is shipped together with conformant BER/DER/XER/PER codecs. The X.509, GSM TAP3, MEGACO, RRC and LDAP encoding and decoding examples are part of the source code distribution. NOTE: THE asn1c PROJECT HAS LARGELY MOVED TO GITHUB: http://github.com/vlm/asn1c
