DiskCryptor is a full disk encryption system for Microsoft Windows that allows the encryption of an entire PC's hard drive or individual partitions – including the ability to encrypt the partition and disk on which the OS is installed.
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.
