TrueCrypt License Version 3.0
Software distributed under this license is distributed on an "AS
IS" BASIS WITHOUT WARRANTIES OF ANY KIND. THE AUTHORS AND
DISTRIBUTORS OF THE SOFTWARE DISCLAIM ANY LIABILITY. ANYONE WHO
USES, COPIES, MODIFIES, OR (RE)DISTRIBUTES ANY PART OF THE
SOFTWARE IS, BY SUCH ACTION(S), ACCEPTING AND AGREEING TO BE
BOUND BY ALL TERMS AND CONDITIONS OF THIS LICENSE. IF YOU DO NOT
ACCEPT THEM, DO NOT USE, COPY, MODIFY, NOR (RE)DISTRIBUTE THE
SOFTWARE, NOR ANY PART(S) THEREOF.
I. Definitions
1. "This Product" means the work (including, but not limited to,
source code, graphics, texts, and accompanying files) made
available under and governed by this version of this license
("License"), as may be indicated by, but is not limited to,
copyright notice(s) attached to or included in the work.
2. "You" means (and "Your" refers to) an individual or a legal
entity (e.g., a non-profit organization, commercial
organization, government agency, etc.) exercising permissions
granted by this License.
3. "Modification" means (and "modify" refers to) any alteration
of This Product, including, but not limited to, addition to or
deletion from the substance or structure of This Product,
translation into another language, repackaging, alteration or
removal of any file included with This Product, and addition of
any new files to This Product.
4. "Your Product" means This Product modified by You, or any
work You derive from (or base on) any part of This Product. In
addition, "Your Product" means any work in which You include any
(modified or unmodified) portion of This Product. However, if
the work in which you include it is an aggregate software
distribution (such as an operating system distribution or a
cover CD-ROM of a magazine) containing multiple separate
products, then the term "Your Product" includes only those
products (in the aggregate software distribution) that use,
include, or depend on a modified or unmodified version of This
Product (and the term "Your Product" does not include the whole
aggregate software distribution). For the purposes of this
License, a product suite consisting of two or more products is
considered a single product (operating system distributions and
cover media of magazines are not considered product suites).
5. "Distribution" means (and "distribute" refers to), regardless
of means or methods, conveyance, transfer, providing, or making
available of This/Your Product or portions thereof to third
parties (including, but not limited to, making This/Your
Product, or portions thereof, available for download to third
parties, whether or not any third party has downloaded the
product, or any portion thereof, made available for download).
II. Use, Copying, and Distribution of This Product
1. Provided that You comply with all applicable terms and
conditions of this License, You may make copies of This Product
(unmodified) and distribute copies of This Product (unmodified)
that are not included in another product forming Your Product
(except as permitted under Chapter III). Note: For terms and
conditions for copying and distribution of modified versions of
This Product, see Chapter III.
2. Provided that You comply with all applicable terms and
conditions of this License, You may use This Product freely (see
also Chapter III) on any number of computers/systems for non-
commercial and/or commercial purposes.
III. Modification, Derivation, and Inclusion in Other Products
1. If all conditions specified in the following paragraphs in
this Chapter (III) are met (for exceptions, see Section III.2)
and if You comply with all other applicable terms and conditions
of this License, You may modify This Product (thus forming Your
Product), derive new works from This Product or portions thereof
(thus forming Your Product), include This Product or portions
thereof in another product (thus forming Your Product, unless
defined otherwise in Chapter I), and You may use (for non-
commercial and/or commercial purposes), copy, and/or distribute
Your Product.
a. The name of Your Product (or of Your modified version of
This Product) must not contain the name TrueCrypt (for
example, the following names are not allowed: TrueCrypt,
TrueCrypt+, TrueCrypt Professional, iTrueCrypt, etc.) nor
any other names confusingly similar to the name TrueCrypt
(e.g., True-Crypt, True Crypt, TruKrypt, etc.)
All occurrences of the name TrueCrypt that could reasonably
be considered to identify Your Product must be removed from
Your Product and from any associated materials. Logo(s)
included in (or attached to) Your Product (and in/to
associated materials) must not incorporate and must not be
confusingly similar to any of the TrueCrypt logos
(including, but not limited to, the non-textual logo
consisting primarily of a key in stylized form) or
portion(s) thereof. All graphics contained in This Product
(logos, icons, etc.) must be removed from Your Product (or
from Your modified version of This Product) and from any
associated materials.
b. The following phrases must be removed from Your Product
and from any associated materials, except the text of this
License: "A TrueCrypt Foundation Release", "Released by
TrueCrypt Foundation", "This is a TrueCrypt Foundation
release."
c. Phrase "Based on TrueCrypt, freely available at
http://www.truecrypt.org/" must be displayed by Your Product
(if technically feasible) and contained in its
documentation. Alternatively, if This Product or its portion
You included in Your Product constitutes only a minor
portion of Your Product, phrase "Portions of this product
are based in part on TrueCrypt, freely available at
http://www.truecrypt.org/" may be displayed instead. In each
of the cases mentioned above in this paragraph,
"http://www.truecrypt.org/" must be a hyperlink (if
technically feasible) pointing to http://www.truecrypt.org/
and You may freely choose the location within the user
interface (if there is any) of Your Product (e.g., an
"About" window, etc.) and the way in which Your Product will
display the respective phrase.
Your Product (and any associated materials, e.g., the
documentation, the content of the official web site of Your
Product, etc.) must not present any Internet address
containing the domain name truecrypt.org (or any domain name
that forwards to the domain name truecrypt.org) in a manner
that might suggest that it is where information about Your
Product may be obtained or where bugs found in Your Product
may be reported or where support for Your Product may be
available or otherwise attempt to indicate that the domain
name truecrypt.org is associated with Your Product.
d. The complete source code of Your Product must be freely
and publicly available (for exceptions, see Section III.2)
at least until You cease to distribute Your Product. This
condition can be met in one or both of the following ways:
(i) You include the complete source code of Your Product
with every copy of Your Product that You make and distribute
and You make all such copies of Your Product available to
the general public free of charge, and/or (ii) You include
information (valid and correct at least until You cease to
distribute Your Product) about where the complete source
code of Your Product can be obtained free of charge (e.g.,
an Internet address) or for a reasonable reproduction fee
with every copy of Your Product that You make and distribute
and, if there is a web site officially associated with Your
Product, You include the aforementioned information about
the source code on a freely and publicly accessible web
page to which such web site links via an easily viewable
hyperlink (at least until You cease to distribute Your
Product).
The source code of Your Product must not be deliberately
obfuscated and it must not be in an intermediate form (e.g.,
the output of a preprocessor). Source code means the
preferred form in which a programmer would usually modify
the program.
Portions of the source code of Your Product not contained in
This Product (e.g., portions added by You in creating Your
Product, whether created by You or by third parties) must be
available under license(s) that (however, see also
Subsection III.1.e) allow(s) anyone to modify and derive new
works from the portions of the source code that are not
contained in This Product and to use, copy, and redistribute
such modifications and/or derivative works. The license(s)
must be perpetual, non-exclusive, royalty-free, no-charge,
and worldwide, and must not invalidate, weaken, restrict,
interpret, amend, modify, interfere with or otherwise affect
any part, term, provision, or clause of this License. The
text(s) of the license(s) must be included with every copy
of Your Product that You make and distribute.
e. You must not change the license terms of This Product in
any way (adding any new terms is considered changing the
license terms even if the original terms are retained),
which means, e.g., that no part of This Product may be put
under another license. You must keep intact all the legal
notices contained in the source code files. You must include
the following items with every copy of Your Product that You
make and distribute: a clear and conspicuous notice stating
that Your Product or portion(s) thereof is/are governed by
this version of the TrueCrypt License, a verbatim copy of
this version of the TrueCrypt License (as contained herein),
a clear and conspicuous notice containing information about
where the included copy of the License can be found, and an
appropriate copyright notice.
2. You are not obligated to comply with Subsection III.1.d if
Your Product is not distributed (i.e., Your Product is available
only to You).
IV. Disclaimer of Liability, Disclaimer of Warranty,
Indemnification
You expressly acknowledge and agree to the following:
1. IN NO EVENT WILL ANY (CO)AUTHOR OF THIS PRODUCT, OR ANY
APPLICABLE INTELLECTUAL-PROPERTY OWNER, OR ANY OTHER PARTY WHO
MAY COPY AND/OR (RE)DISTRIBUTE THIS PRODUCT OR PORTIONS THEREOF,
AS MAY BE PERMITTED HEREIN, BE LIABLE TO YOU OR TO ANY OTHER

TO, CORRUPTION OR LOSS OF DATA, ANY LOSSES SUSTAINED BY YOU OR
THIRD PARTIES, A FAILURE OF THIS PRODUCT TO OPERATE WITH ANY
OTHER PRODUCT, PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES, OR
BUSINESS INTERRUPTION), WHETHER IN CONTRACT, STRICT LIABILITY,
TORT (INCLUDING, BUT NOT LIMITED TO, NEGLIGENCE) OR OTHERWISE,
ARISING OUT OF THE USE, COPYING, MODIFICATION, OR
(RE)DISTRIBUTION OF THIS PRODUCT (OR A PORTION THEREOF) OR OF
YOUR PRODUCT (OR A PORTION THEREOF), OR INABILITY TO USE THIS
PRODUCT (OR A PORTION THEREOF), EVEN IF SUCH DAMAGES (OR THE
POSSIBILITY OF SUCH DAMAGES) ARE/WERE PREDICTABLE OR KNOWN TO
ANY (CO)AUTHOR, INTELLECTUAL-PROPERTY OWNER, OR ANY OTHER PARTY.
2. THIS PRODUCT IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY
KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING, BUT NOT
LIMITED TO, THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A
PARTICULAR PURPOSE, AND NON-INFRINGEMENT. THE ENTIRE RISK AS TO
THE QUALITY AND PERFORMANCE OF THIS PRODUCT IS WITH YOU. SHOULD
THIS PRODUCT PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
NECESSARY SERVICING, REPAIR, OR CORRECTION.
3. THIS PRODUCT MAY INCORPORATE IMPLEMENTATIONS OF CRYPTOGRAPHIC
ALGORITHMS THAT ARE REGULATED (E.G., SUBJECT TO EXPORT/IMPORT
CONTROL REGULATIONS) OR ILLEGAL IN SOME COUNTRIES. IT IS SOLELY
YOUR RESPONSIBILITY TO VERIFY THAT IT IS LEGAL TO IMPORT AND/OR
(RE)EXPORT AND/OR USE THIS PRODUCT (OR PORTIONS THEREOF) IN
COUNTRIES WHERE YOU INTEND TO USE IT AND/OR TO WHICH YOU INTEND
TO IMPORT IT AND/OR FROM WHICH YOU INTEND TO EXPORT IT, AND IT
IS SOLELY YOUR RESPONSIBILITY TO COMPLY WITH ANY APPLICABLE
REGULATIONS, RESTRICTIONS, AND LAWS.
4. YOU SHALL INDEMNIFY, DEFEND AND HOLD ALL (CO)AUTHORS OF THIS
PRODUCT, AND APPLICABLE INTELLECTUAL-PROPERTY OWNERS, HARMLESS
FROM AND AGAINST ANY AND ALL LIABILITY, DAMAGES, LOSSES,
SETTLEMENTS, PENALTIES, FINES, COSTS, EXPENSES (INCLUDING
REASONABLE ATTORNEYS' FEES), DEMANDS, CAUSES OF ACTION, CLAIMS,
ACTIONS, PROCEEDINGS, AND SUITS, DIRECTLY RELATED TO OR ARISING
OUT OF YOUR USE, INABILITY TO USE, COPYING, (RE)DISTRIBUTION,
IMPORT AND/OR (RE)EXPORT OF THIS PRODUCT (OR PORTIONS THEREOF)
AND/OR YOUR BREACH OF ANY TERM OF THIS LICENSE.

associated with (or applying to) This Product, except for fair
use as defined by applicable law and except for use expressly
permitted or required by this License. Any attempt otherwise to
use trademarks associated with (or applying to) This Product
automatically and immediately terminates Your rights under This
License and may constitute trademark infringement (which may be
prosecuted).

1. ANYONE WHO USES AND/OR COPIES AND/OR MODIFIES AND/OR CREATES
DERIVATIVE WORKS OF AND/OR (RE)DISTRIBUTES THIS PRODUCT, OR ANY

"Options:\n"
"\n"
"--display-password\n"
" Display password characters while typing.\n"
"\n"
"--encryption=ENCRYPTION_ALGORITHM\n"
" Use specified encryption algorithm when creating a new volume.\n"
"\n"
"--filesystem=TYPE\n"
" Filesystem type to mount. The TYPE argument is passed to mount(8) command\n"
" with option -t. Default type is 'auto'. When creating a new volume, this\n"
" option specifies the filesystem to be created on the new volume (only 'FAT'\n"
" and 'none' TYPE is allowed). Filesystem type 'none' disables mounting or\n"
" creating a filesystem.\n"
"\n"
"--force\n"
" Force mounting of a volume in use, dismounting of a volume in use, or\n"
" overwriting a file. Note that this option has no effect on some platforms.\n"

" potentially insecure as the password may be visible in the process list\n"
" (see ps(1)) and/or stored in a command history file or system logs.\n"
"\n"
"--protect-hidden=yes|no\n"
" Write-protect a hidden volume when mounting an outer volume. Before mounting\n"
" the outer volume, the user will be prompted for a password to open the hidden\n"
" volume. The size and position of the hidden volume is then determined and the\n"
" outer volume is mounted with all sectors belonging to the hidden volume\n"
" protected against write operations. When a write to the protected area is\n"

" Do not encrypt free space when creating a device-hosted volume. This option\n"
" must not be used when creating an outer volume.\n"
"\n"
"--random-source=FILE\n"
" Use FILE as a source of random data (e.g., when creating a volume) instead\n"
" of requiring the user to type random characters.\n"
"\n"
"--slot=SLOT\n"
" Use specified slot number when mounting, dismounting, or listing a volume.\n"
"\n"
"--size=SIZE\n"
" Use specified size in bytes when creating a new volume.\n"

"\n"
"--token-lib=LIB_PATH\n"
" Use specified PKCS #11 security token library.\n"
"\n"
"--volume-type=TYPE\n"
" Use specified volume type when creating a new volume. TYPE can be 'normal'\n"
