DiskCryptor 
DiskCryptor main windowDeveloper(s) ntldr <ntldr(at)diskcryptor.net> Stable release 0.9.593.106 / April 24, 2010 Preview release 1.0.735.111 beta[1] / 03 June 2011 Written in C, Assembly Operating system Microsoft Windows NT 5+ Available in English Type Disk encryption software License GNU GPLv3 Website http://diskcryptor.net DiskCryptor is the first[2][dubious ] open source (GPL) full disk encryption system for MS Windows[3][4] that allows the encryption of an entire PC's harddrive or individual partitions – including the ability to encrypt the partition and disk on which the OS is installed.[5]
DiskCryptor was originally designed to replace commercial disk encryption systems such as DriveCrypt Plus Pack and PGP Whole Disk Encryption, and uses either AES-256, Twofish, Serpent or a combination of cascaded algorithms in XTS mode to carry out encryption.
The project was originally started by a former TrueCrypt user and forum member which goes by the name of 'ntldr'. It was originally fully compatible with TrueCrypt's container format but has since improved on the format in order to allow data-in-place encryption on Windows XP, to allow the system partition to have exactly the same format as non-system partitions and to support future project plans.

- Support for hardware AES acceleration:
- AES-NI instruction set on new Intel CPU;
- PadLock extensions on VIA processors.
- Support for hardware AES acceleration:
- Broad choice in configuration of booting an encrypted OS. Support for various multi-boot options.
- Full support for external storage devices.
- Option to create encrypted CDs and DVDs.
- Full support for encryption of external USB storage devices.
- Automatic mounting of disk partitions and external storage devices.
- Support for hotkeys and optional command-line interface (CLI).
- Open license GNU GPLv3.
For limitations in the current version, as well as other technical information, see official website.
Encryption algorithms
All algorithms are implemented in XTS mode.
Hash function
- prf HMAC-SHA-512
Performance
On an Intel Core 2 Quad (Q6600) CPU data encryption speed amounts to 104 MB/s per core.[6] Crypto-algorithms for the x86 version are implemented in assembly language, the implementation having a maximum number of optimizations for the Intel Core line of processors, however it performs sufficiently fast on any other processors as well. Almost all possible enhancements to improve the performance have been applied such as the AES algorithm code is being dynamically generated with optimization made for the usage of a particular key.[6]
Supported OS
Operating systems Service pack Bitness Windows 2000 SP0–SP4 x86 XP SP0–SP3 x86, x64 Server 2003 SP0–SP2 x86, x64 Vista SP0–SP2 x86, x64 Server 2008 SP0–SP2 x86, x64 7 x86, x64 Server 2008 R2 x64 See also
