我找網路找半天,只有找到PGP,但是用那個實作不具彈性有沒有RSA的VCL元件,示免費的,我之前找看到的都是要錢的謝謝

willchen您好: 試試 Turbopower LockBox(OpenSource)吧 http://sourceforge.net/projects/tplockbox/ http://www.turbopower.com/products/lockbox/ LockBox is a cross-platform toolkit for data encryption. It contains routines & components for use with Borland Delphi, C Builder, & Kylix. It provides support for Blowfish, RSA, MD5, SHA-1, DES, triple- DES, Rijndael, & digital signing of messages.

Public key encryption with RSA New!	Let LockBox generate and publish public keys so your correspondents can encrypt data meant only for you.
Extra secure hashing with advanced MD5 and SHA-1 support New!	Instantly generate your own secure hashes for strings, buffers, streams and entire files using MD5 and SHA-1.
Digital signature support New!	Digitally sign messages and documents using the standard Digital Signature Algorithm (DSA)
Rijndael Advanced Encryption Standard support New!	Fully access the new Rijndael algorithm, the new standard designed to replace the older DES standard.
Enhanced String encryption New!	Now, one of the most popular reasons for using LockBox is also the easiest!
Easy to use LockBox components New!	For the first time, LockBox now comes with easy to use components that make it easier than ever before to access the library's capabilities.
Powerful Data Encryption Standard (DES) support	A full implementation of the DES symmetric algorithm. The keys are 56 bits in length, but for even greater security, try LockBoxs version of triple-DES, the algorithm that encrypts by encoding your data three times with DES!
Ready to go with cross-platform support for Windows and Linux using Borland Delphi, C Builder, or Kylix	LockBox 2 is a great value, with support for Windows and Linux in one product. There's nothing extra to license. Use it with Delphi, C Builder and Kylix.
Full source code included	See exactly how it works, learn by example and use professional TurboPower techniques in your own projects.
Expanded, enhanced documentation	New manual explains not only how to use LockBox 2 but how it works "under the covers."
100% royalty-free	No royalty payments, no matter how many times you use LockBox 2 in your projects.

謝謝這位高手的解答,但是這個東西我之前也下載過,在Delphi可以運作,但是在BCB好像有bpi不能compiler,這是什麼原因?? 我也按照他本身說明來安裝...但BCB就是compiler 安裝component出問題

您有按照以下步驟試過?

1. Introduction    LockBox is a cross-platform toolkit for data encryption. It contains
routines & components for use with Borland Delphi, C  Builder, &
Kylix. It provides support for Blowfish, RSA, MD5, SHA-1, DES, triple-
DES, Rijndael, & digital signing of messages.    This is a source-only release of TurboPower LockBox. It includes
designtime and runtime packages for Delphi 3 through 7 and C  Builder
3 through 6.    ==============================================    2. Package names    TurboPower LockBox package names have the following form:      LNNNMKVV.*
   |  |||
   |  || ------ VV  VCL version (30=Delphi 3, 40=Delphi 4, 70=Delphi 7)
   |  | ------- K   Kind of package (R=runtime, D=designtime)
   |   -------- M   Product-specific modifier (typically underscore, V = VCL, C = CLX)
    ----------- NNN Product version number (e.g., 207=version 2.07)    For example, the LockBox CLX designtime package files for Delphi 7 have
the filename L207CD70.*.    ==============================================    3. Installation    To install TurboPower LockBox into your IDE, take the following steps:      1. Unzip the release files into a directory (e.g., d:\lockbox).      2. Start Delphi or C  Builder.      3. Add the source subdirectory (e.g., d:\lockbox\source) to the
     IDE's library path.      4. Open & install the designtime package specific to the IDE being
     used. The IDE should notify you the components have been
     installed.         a. For C  Builder 6 and Delphi 6 or higher, install the VCL
        design-time package (e.g., LxxxVDxx.*) when using LockBox
        classes with VCL applications.         b. For C  Builder 6 and Delphi 6 or higher, install the CLX
        design-time package (e.g., LxxxCDxx.*) when using LockBox
        classes with CLX applications.      5. Make sure the PATH environmental variable contains the directory
     in which the compiled packages (i.e., BPL or DPL files) were
     placed.    ==============================================

請說明清楚您的C Builder 安裝版本與產生狀況? 我在C Builder 5 SP1 ADO Updat1下安裝無誤! HAVE A NICE DAY FOR YOU 發表人 - axsoft 於 2003/06/25 13:39:24

謝謝你的回應,我已經安裝正常沒問題了,對了,順便問個問題怎麼把AnsiString格式的東西存入檔案(txt)不會發生文字格式的變化?? 因為我把加密後的文字用TStringList寫入檔案之後,結果在解密部分用 TStringList讀回來發現會程式執行錯誤,我想請問你有遇過這問題嗎??

不知道各位大大給你的答案是否足夠你的需求了呢? 如果是的話, 是不是該給個分數, 來獎勵人家一下呢? 至於怎麼把AnsiString寫入檔案已經離題, 而且你也換了一個標題發問, 因此原來免費的RSA VCL元件是不是該結案了呢? 以上只是個人的建議
