Open Source Linux Cryptography Software

VeraCrypt is a free disk encryption software brought to you by IDRIX (https://www.idrix.fr) and based on TrueCrypt 7.1a. It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It also solves many vulnerabilities and security issues found in TrueCrypt. This enhanced security adds some delay ONLY to the opening of encrypted partitions without any performance impact to the application use phase. This is acceptable to the legitimate owner but it makes it much harder for an attacker to gain access to the encrypted data. All released files are PGP signed with key ID=0x680D16DE, available on key servers and downloadable at https://www.idrix.fr/VeraCrypt/VeraCrypt_PGP_public_key.asc VeraCrypt can mount TrueCrypt volumes. It also can convert them to VeraCrypt format. Documentation: https://www.veracrypt.fr/en/Documentation.html FAQ : https://www.veracrypt.fr/en/FAQ.html

mcrypt, and the accompanying libmcrypt, are intended to be replacements for the old Unix crypt, except that they are under the GPL and support an ever-wider range of algorithms and modes.

Poptop is an open source implementation of a PPTP server. Running under x86 or embedded Motorola ColdFire architectures Poptop provides full interoperability with the Microsoft PPTP VPN client.

JSignPdf is an open-source Java application that adds digital signatures to PDF documents.

Password Safe is a password database utility. Users can keep their passwords securely encrypted on their computers. A single Safe Combination unlocks them all.

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.

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.

Cryptomator is a free and open source project that offers multi-platform, transparent client side encryption of your files in the cloud. It works with just about any cloud storage service; is totally transparent so you can work with your files how you normally would; and secure with a 256-bit key length AES encryption. It’s also simple and easy to use with no need for different accounts, key management, cloud access grants or cipher configurations.

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.

axTLS is a TLSv1 SSL library designed specifically for embedded devices, with a highly configurable interface for small memory footprints.

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.

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.

KeyStore Explorer is a free GUI replacement for the Java command-line utilities keytool and jarsigner.

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

FileVerifier++ is a Windows utility for calculating hashes using a number of algorithms including CRC32, MD5, SHA-1, SHA-256/224/384/512, WHIRLPOOL, and RIPEMD-128/160/256/320. Supported hash file formats include MD5SUM .MD5, SFV, BSD CKSUM, and others.

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.

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/
