According to the TrueCrypt Team, Hafner claimed in the email that the acknowledged author of E4M, developer Paul Le Roux, had stolen the source code from SecurStar as an employee.

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 On, the TrueCrypt website announced that the project was no longer maintained and recommended users find alternative solutions.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