RealCrypt Alternatives

TrueCrypt

[TrueCrypt is not exactly "Open Source", but the source is available. See the reviews to get more information.] TrueCrypt is a disk encryption software for Windows Vista/XP, Mac OS X, and Linux. Creates a virtual encrypted disk within a file and mounts it as a real disk. Encrypts an entire partition or storage device such as USB flash drive or hard drive. Encrypts a partition or drive where Windows is installed (pre-boot authentication).

Features:

• Drive Encryption
• Encryption
• Portable
• Security focused

LUKS

LUKS is the standard for Linux hard disk encryption. By providing a standard on-disk-format, it does not only facilitate compatibility among distributions, but also provides secure management of multiple user passwords. In contrast to existing solution, LUKS stores all setup necessary setup information in the partition header, enabling the user to transport or migrate his data seamlessly. LUKS was designed according to TKS1, a template design developed in TKS1 for secure key setup.

Features:

• Data-encryption
• Drive Encryption

CipherShed

A fork of the now-discontinued TrueCrypt. CipherShed is a program that can be used to create encrypted files or encrypt entire drives (including USB flash drives and external HDDs). There’s no complicated commands or knowledge required; a simple wizard guides you step-by-step through every process. After creating an encrypted file or disk drive, the encrypted volume is mounted through CipherShed.

DiskCryptor

DiskCryptor is the only truly free solution, provided under GNU General Public License (GPLv3), which offers encryption of all disk partitions, including the system partition. The main criteria for open-source software is the availability of its source code under one of the open source licenses. The only open-source alternative to DiskCryptor that has comparable features is TrueCrypt.

EncFS

EncFS provides an encrypted filesystem in user-space. It runs without any special permissions and uses the FUSE library and Linux kernel module to provide the filesystem interface. You can find links to source and binary releases below. EncFS is open source software, licensed under the GPL. As with most encrypted filesystems, Encfs is meant to provide security against off-line attacks; ie your notebook or backups fall into the wrong hands, etc.

Windows BitLocker

BitLocker drive encryption provides offline data and operating system protection by ensuring that the drive is not tampered with the operating system is offline. BitLocker drive encryption uses a TPM, either discrete or firmware, that supports the Static Root of Trust Measurement as defined by the Trusted Computing Group. BitLocker is capable of encrypting entire hard drives, including both system and data drives.

Features:

• Create bootable USB
• Drive Encryption
• Encryption
• Location Mapping
• Windows Explorer extension

LibreCrypt

LibreCrypt (formerly DoxBox) is an open-source disk encryption for Windows and the successor of FreeOTFE Change of name to 'LibreCrypt' in version 6.2 Features: Easy to use, with a 'wizard' for creating new 'DoxBoxes'. Full transparent encryption, DoxBoxes appear as removable disks in Windows Explorer. Explorer mode lets you access DoxBoxes when you don't have admin permissions.

FileVault

FileVault is a method of using encryption with volumes on Mac computers. Encryption and decryption are performed on the fly. FileVault 2 uses full disk, XTS-AES 128 encryption to help keep your data secure. Using FileVault 2, you can encrypt the contents of your entire drive.

Features:

• Data-encryption
• Drive Encryption
