Hermetic Stego 9.49

軟體性質: 免費試用 ‎檔案大小: 2.25 MB
‎使用者評分: 4.0/5 - ‎1 ‎評分

Hermetic Stego 是一個隱匿程式,它允許您加密和隱藏另一個檔中任何數據檔的內容,以便將數據添加到容器檔中不會明顯改變該檔的外觀。如果已隱藏的檔被刪除,那麼沒有跡象表明它甚至存在,但它仍然可以恢復時,你需要得到它。 程序根據密碼以偽隨機方式在圖像檔中插入數據,並更改圖像檔的其他位以補償隱藏數據引起的修改,以避免修改圖像檔的統計屬性。因此,它比大多數隱版程式安全得多。 此程式允許在一個或多個 BMP 影像檔中隱藏任何大小的檔,並且使用使用者指定的 stego/加密密鑰,以便 (i) 隱藏檔的存在無法檢測(即使使用統計方法的取證軟體)和 (ii) 如果使用使用者指定的 stego 密鑰,則隱藏檔只能由某人提取,使用該軟體,誰知道 stego 密鑰。 Hermetic Stego 允許 (i) 將訊息檔隱藏在單個 BMP 影像檔中或一組 BMP 圖像中,以及 (ii) 從單個 BMP 圖像檔或一組圖像中提取消息檔。 此程式在兩個方面不同於其他此類程式: 1. 要隱藏的資料檔的大小沒有限制,因為 Hermetic Stego 可以隱藏資料檔案,不僅隱藏在單個 BMP 影像檔中,而且隱藏在一組資料檔中 -- 包含資料檔所需的影像數。 2. 資料位隨機插入圖像檔的位元組中,以挫敗使用統計測試來顯示隱藏消息的存在。 3. 該程式可與使用者指定的 stego 密鑰或預設 stego 金鑰一起使用;使用預設 stego 金鑰允許向不知道該 stego 密鑰的其他人發送隱藏數據。

終端使用者許可協定

'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.
