Hermetic Stego 是一个隐匿程序，它允许您加密和隐藏另一个文件中任何数据文件的内容，以便将数据添加到容器文件中不会明显改变该文件的外观。如果已隐藏的文件被删除，那么没有迹象表明它甚至存在，但它仍然可以恢复时，你需要得到它。 程序根据密码以伪随机方式在图像文件中插入数据，并更改图像文件的其他位以补偿隐藏数据引起的修改，以避免修改图像文件的统计属性。因此，它比大多数隐版程序安全得多。 此程序允许在一个或多个 BMP 图像文件中隐藏任何大小的文件，并且使用用户指定的 stego/加密密钥，以便 （i） 隐藏文件的存在无法检测（即使使用统计方法的取证软件）和 （ii） 如果使用用户指定的 stego 密钥，则隐藏文件只能由某人提取，使用该软件，谁知道 stego 密钥。 Hermetic Stego 允许 （i） 将消息文件隐藏在单个 BMP 图像文件中或一组 BMP 图像中，以及 （ii） 从单个 BMP 图像文件或一组图像中提取消息文件。 此程序在两个方面不同于其他此类程序： 1. 要隐藏的数据文件的大小没有限制，因为 Hermetic Stego 可以隐藏数据文件，不仅隐藏在单个 BMP 图像文件中，而且隐藏在一组数据文件中 -- 包含数据文件所需的图像数。 2. 数据位随机插入图像文件的字节中，以挫败使用统计测试来显示隐藏消息的存在。 3. 该程序可与用户指定的 stego 密钥或默认 stego 密钥一起使用;使用默认 stego 密钥允许向不知道该 stego 密钥的其他人发送隐藏数据。

'Hermetic Systems' is the business name of Peter Meyer, [email protected], the developer of this software, and the owner and maintainer of the 'Hermetic Systems' website. The 'Hermetic Stego' software ("the Software") consists of the executable file and the other files installed by the installation program hst_setup.exe obtainable from the 'Hermetic Systems' website (including any future versions). The Software is protected by copyright, which is owned by Hermetic Systems. The Software may be downloaded from the 'Hermetic Systems' website or another authorized download site solely for the purpose of its evaluation with regard to the purchase of a user license. Neither the installation program nor any work derived from it may be distributed further by any means (including via CD or the web) without the permission of the copyright holder. All intellectual property rights related to the Software are owned by Hermetic Systems. You may not rent or lease the Software. You may not modify, translate, reverse engineer, decompile or disassemble the Software or any part thereof or otherwise attempt to derive source code or create derivative works therefrom. You may not remove, alter or destroy any proprietary, trademark or copyright markings or notices contained within the Software. You may not sell or offer for sale any derivative work. Any rights not explicitly granted by Hermetic Systems are reserved. In return for a license fee paid to Hermetic Systems or to one of its authorized representatives or resellers you are granted a license to use the Software in its fully-functional form and you are provided with activation keys for each installation of the Software as follows: (A) If you are a natural person then you receive a single-user license and this entitles you to install, activate and use the Software on a reasonable number of personal computers (e.g., a laptop and a desktop) in your private household or office. (B) If you are an entity other than a natural person (e.g., a corporation) then you are required to purchase a single-user license for each PC on which the software will be made available for use. The function of an activation key is to remove any temporal or functional limitations on a particular installation of the Software. A separate activation key is required for each installation (in other words, an activation key works only on a particular computer). For some programs there are three types of user license: 3-month, 1-year and time-unlimited (a 'perpetual' license). 3-month and 1-year licenses allow use of the software for the stated period beginning on the date of purchase of the license. At the termination of the license period the software will revert to a functionally limited 'demo' version. It may be reactivated by purchasing a new license. In the event that a later version of the software is released, you may update an installation at no charge by downloading and installing the new version. If you change your computer (or make a major hardware modification) you may need to obtain a new activation key. This can be obtained in the same way as before (and at no charge), provided that, in the opinion of Hermetic Systems, the number and frequency of such new activation keys is not unreasonably excessive. A user license is not transferable. Installation of the Software constitutes an agreement that the Software is provided "as is", without any warranties or guarantees. Hermetic Systems makes every effort to ensure that the software is error-free and performs as stated in the online user manual, but does not guarantee this. You assume responsibility for selecting the Software and using it for your intended purposes. In no event shall Hermetic Systems, its resellers or distributors of the Software be liable for any any damages whatsoever arising out of use or inability to use the Software, even if advised of the possibiity of such damages. Note that Hermetic Stego employs encryption and allows use of a 'stego key', which is an encryption key. Data encrypted using Hermetic Stego cannot be decrypted without knowledge of the key which was used to encrypt the data. Hermetic Stego has no 'back door'. The encryption key is not concealed in the stego images or anywhere else. If the key is lost or is unavailable then there is no way known to recover the encrypted data. This software must be used with due attention to this warning. Hermetic Systems will not be responsible for damages of any kind arising from loss of data resulting from forgetting or losing stego keys. Encrypting information is like using a padlock to lock a box -- when encrypting data always make sure that you can find the key when you need it.
