GnuPG (the GNUPrivacy Guardor GPG) isGNU's toolfor securecommunicationand datastorage. It canbe used toencrypt dataand to createdigitalsignatures. Itincludes anadvanced keymanagementfacility and iscompliant withthe proposedOpenPGPInternetstandard asdescribed inRFC2440. Assuch, it ismeant to becompatible withPGP from NAI,Inc. Because itdoes not useany patentedalgorithms, itcan be usedwithout anyrestrictions.
The Mandossystem allowscomputers tohave encryptedroot filesystems and atthe same timebe capable ofremote orunattendedreboots. Thecomputers run asmall clientprogram in theinitial RAMdiskenvironmentwhich willcommunicatewith a serverover a network.All networkcommunicationis encryptedusing TLS. Theclients areidentified bythe serverusing anOpenPGP keythat is uniqueto each client.The serversends theclients anencryptedpassword. Theencryptedpassword isdecrypted by
Secrets can beused to split asecret textinto shares tobe distributedto friends.When allfriends agree,the shares canbe combined toretrieve theoriginal secrettext, forinstance togive consensualaccess to alost pin, apassword, alist ofpasswords, aprivatedocument or akey to anencryptedvolume. Secretsharing can beuseful in manydifferentsituations andthis tool is asimple and welldocumented freeand open sourceimplementationavailable foranyone to usefrom thiswebsite,
Naamari isAES&SHA-basedcrypto-synchronizerforcloud/remotefile storage,withcryptographicand transportmodules beingseparateapplications. It works with 4locations. 1st:local dir withoriginal files.2nd: dircontainingfolderstructure andnames of filesplaced intostorage (butnot content).3rd & 4th -storages: local(another localdir) and remote(say, a cloud).In storages,there are nofolders, fileshavepseudo-randomnames andencryptedcontent("flattening").

Tomb is asystem to makestrongencryption easyfor everydayuse. A tomb islike a lockedfolder that canbe safelytransported andhidden in afilesystem. Itskeys can bekept separate;for example,you can keepthe tomb onyour computerand its key ona USB stick.Tomb is writtenin code that iseasy to reviewand linkssharedcomponents: itconsists of aZShell scriptand desktopintegrationapps; it usesstandard GNUtools and thecrypto API ofthe Linuxkernel(dm-crypt) viacryptsetup.

gpgpwd is aterminal-basedpasswordmanager. Itstores a listof passwordsand theirassociatedusernames in aGnuPG-encryptedfile, andallows you toeasilyretrieve,change, and addto that file asneeded. Italso generatesrandompasswords whichyou can use,easily allowingyou to have one"masterpassword"(for your gpgkey), with oneunique andrandom passwordfor eachwebsite orservice youuse, ensuringthat your otheraccounts staysafe even ifone passwordgets leaked. gpgpwd can als
