E4M
Encryption for the Masses (E4M) is a free disk encryption software for Windows NT and Windows 9x families of operating systems. E4M is discontinued; it is no longer maintained. Its author, former criminal cartel boss Paul Le Roux, joined Shaun Hollingworth (the author of the Scramdisk) to produce the commercial encryption product DriveCrypt for the security company SecurStar. The popular source-available freeware program TrueCrypt is based on E4M's source code. However, TrueCrypt uses a different container format than E4M, which makes it impossible to use one of these programs to access an encrypted volume created by the other. Allegation of stolen source code Shortly after TrueCrypt version 1.0 was released in February 2004, the TrueCrypt Team reported receiving emails from Wilfried Hafner, manager of SecurStar, claiming that Paul Le Roux had stolen the source code of E4M from SecurStar as an employee. According to the TrueCrypt Team, the emails stated that Le Roux illegally ...

Paul Le Roux
Paul Calder Le Roux (born 24 December 1972) is a former programmer, former criminal cartel boss, and informant to the US Drug Enforcement Administration (DEA). In 1999, he created E4M, a free and open-source disk encryption software program for Microsoft Windows, and is sometimes credited for open-source TrueCrypt, which is based on E4M's code, though he denies involvement with TrueCrypt. Le Roux was arrested on 26 September 2012 for conspiracy to import narcotics into the United States, and agreed to cooperate with authorities in exchange for a lesser sentence and immunity to any crimes he might admit to later. He subsequently admitted to arranging or participating in seven murders, carried out as part of an extensive illegal business empire. Le Roux was sentenced to 25 years in prison in June 2020. Early life Le Roux was born on 24 December 1972, at Lady Rodwell Maternity Home in Bulawayo, Zimbabwe and given up for adoption. His birth certificate gives his first name as "u ...

TrueCrypt
TrueCrypt is a discontinued source-available freeware utility used for on-the-fly encryption (OTFE). It can create a virtual encrypted disk within a file, or encrypt a partition or the whole storage device (pre-boot authentication). On 28 May 2014, the TrueCrypt website announced that the project was no longer maintained and recommended users find alternative solutions. Though development of TrueCrypt has ceased, an independent audit of TrueCrypt (published in March 2015) has concluded that no significant flaws are present. Two projects forked from TrueCrypt: VeraCrypt (active) and CipherShed (abandoned). History TrueCrypt was initially released as version 1.0 in February 2004, based on E4M (Encryption for the Masses). Several versions and many additional minor releases have been made since then, with the most current version being 7.1a. E4M and SecurStar dispute Original release of TrueCrypt was made by anonymous developers called "the TrueCrypt Team". Shortly after ...

Comparison Of Disk Encryption Software
This is a technical feature comparison of different disk encryption software. Background information Operating systems Features * Hidden containers: Whether hidden containers (an encrypted container (A) within another encrypted container (B) so the existence of container A can not be established) can be created for deniable encryption. Note that some modes of operation like CBC with a plain IV can be more prone to watermarking attacks than others. * Pre-boot authentication: Whether authentication can be required before booting the computer, thus allowing one to encrypt the boot disk. * Single sign-on: Whether credentials provided during pre-boot authentication will automatically log the user into the host operating system, thus preventing password fatigue and reducing the need to remember multiple passwords. * Custom authentication: Whether custom authentication mechanisms can be implemented with third-party applications. * Multiple keys: Whether an encrypted volume can have m ...

Scramdisk
''Scramdisk'' is a free on-the-fly encryption program for Windows 95, Windows 98, and Windows Me. A non-free version was also available for Windows NT. The original ''Scramdisk'' is no longer maintained; its author, Shaun Hollingworth, joined Paul Le Roux (the author of E4M) to produce Scramdisk's commercial successor, '' DriveCrypt''. The author of Scramdisk provided a driver for Windows 9x, and the author of E4M provided a driver for Windows NT, enabling cross-platform versions of both programs. There is a new project called ''Scramdisk 4 Linux'' which provides access to Scramdisk and TrueCrypt containers. Older versions of TrueCrypt included support for Scramdisk. Licensing Although Scramdisk's source code is still available, it's stated that it was only released and licensed for private study and not for further development. However, because it contains an implementation of the MISTY1 Encryption Algorithm (by Hironobu Suzuki, a.k.a. H2NP) licensed under the GNU GPL Version ...

Open-source Software
Open-source software (OSS) is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to participate online in development, making the number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software. Open-source software development can bring in diverse perspectives beyond those of a single company. A 2008 report by the Standish Group stated that adoption of open-source software models has resulted in savings of about $60 billion per year for consumers. Open source code can be used for studying and allows capable end users to adapt software to their personal needs in a similar way user scripts an ...

Disk Encryption Software
Disk encryption software is computer security software that protects the confidentiality of data stored on computer media (e.g., a hard disk, floppy disk, or USB device) by using disk encryption. Compared to access controls commonly enforced by an operating system (OS), encryption passively protects data confidentiality even when the OS is not active, for example, if data is read directly from the hardware or by a different OS. In addition crypto-shredding suppresses the need to erase the data at the end of the disk's lifecycle. Disk encryption generally refers to wholesale encryption that operates on an entire volume mostly transparently to the user, the system, and applications. This is generally distinguished from file-level encryption that operates by user invocation on a single file or group of files, and which requires the user to decide which specific files should be encrypted. Disk encryption usually includes all aspects of the disk, including directories, so that an adver ...

Disk Encryption
Disk encryption is a technology which protects information by converting it into unreadable code that cannot be deciphered easily by unauthorized people. Disk encryption uses disk encryption software or hardware to encrypt every bit of data that goes on a disk or disk volume. It is used to prevent unauthorized access to data storage. The expression ''full disk encryption (FDE)'' (or ''whole disk encryption'') signifies that everything on the disk is encrypted, but the master boot record (MBR), or similar area of a bootable disk, with code that starts the operating system loading sequence, is not encrypted. Some hardware-based full disk encryption systems can truly encrypt an entire boot disk, including the MBR. Transparent encryption Transparent encryption, also known as real-time encryption and on-the-fly encryption (OTFE), is a method used by some disk encryption software. "Transparent" refers to the fact that data is automatically encrypted or decrypted as it is loaded or sa ...

Freeware
Freeware is software, most often proprietary, that is distributed at no monetary cost to the end user. There is no agreed-upon set of rights, license, or EULA that defines ''freeware'' unambiguously; every publisher defines its own rules for the freeware it offers. For instance, modification, redistribution by third parties, and reverse engineering are permitted by some publishers but prohibited by others. Unlike with free and open-source software, which are also often distributed free of charge, the source code for freeware is typically not made available. Freeware may be intended to benefit its producer by, for example, encouraging sales of a more capable version, as in the freemium and shareware business models. History The term ''freeware'' was coined in 1982 by Andrew Fluegelman, who wanted to sell PC-Talk, the communications application he had created, outside of commercial distribution channels. Fluegelman distributed the program via a process now termed '' shareware''. ...

Windows 9x
Windows 9x is a generic term referring to a series of Microsoft Windows computer operating systems produced from 1995 to 2000, which were based on the Windows 95 kernel and its underlying foundation of MS-DOS, both of which were updated in subsequent versions. The first version in the 9x series was Windows 95, which was succeeded by Windows 98 and then Windows Me, which was the third and last version of Windows on the 9x line, until the series was superseded by Windows XP. Windows 9x is predominantly known for its use in home desktops. In 1998, Windows made up 82% of operating system market share. Internal release versions for versions of Windows 9x are 4.x. The internal versions for Windows 95, 98, and Me are 4.0, 4.1, and 4.9, respectively. Previous MS-DOS-based versions of Windows used version numbers of 3.2 or lower. Windows NT, which was aimed at professional users such as networks and businesses, used a similar but separate version number between 3.1 and 4.0. All versio ...
