[[File:BlowfishDLL.7z]] - DLL plug-in library

== Description ==

A NSIS plug-in that allow you to encrypt/decrypt a message using the [[Wikipedia:Blowfish (cipher)|Blowfish]] algorithm. It's just a simple DLL file (copy it to your NSIS Plugin folder) that exports two NSIS-aware functions:

*encrypt
*decrypt

C++ '''source code included''' (''it is also my 1st C++ program and 1st NSIS plug-in I ever wrote, too'').
It was tested with NSIS v2.45 but should work with some older versions too.

Parts of these sample programs are derivative works based on the work of the following individuals:
*Base64 encoding/decoding - AMMimeUtils by Anders Molin. Original source is available on the Code Project at http://www.codeproject.com/string/ammimeutils.asp
*Blowfish encryption/decryption - Blowfish by Bruce Schneier. Original source is available at Bruce Schneier's website: http://www.schneier.com

== DLL Functions ==

=== blowfish::encrypt ===

Encrypts an text using a password key.

==== Syntax ====

<highlight-nsis>
blowfish::encrypt <text-to-encrypt> <password-key>
</highlight-nsis>

==== Parameters ====
*<text-to-encrypt> : a string of chars to be encrypted
*<password-key> : the password used to encrypt the string; password-key must be 8-56 bytes long

==== Return Value ====
* On success: first item on stack will be "0", next item on the stack will be the encrypted text.
* On failure: first item on stack will be "1", next item on the stack will be the error message.

==== Example ====

<highlight-nsis>
blowfish::encrypt "the text I want to encrypt" "a strong password"
Pop $0 ; 0 on success, 1 on failure
Pop $1 ; encrypted message on success, error message on failure
</highlight-nsis>

=== blowfish::decrypt ===

Decrypts an Blowfish encrypted text using the corresponding password key.

==== Syntax ====

<highlight-nsis>
blowfish::decrypt <text-to-decrypt> <password-key>
</highlight-nsis>

==== Parameters ====
*<text-to-decrypt> : a string of chars to be decrypted
*<password-key> : the password used to decrypt the string; password-key must be 8-56 bytes long

==== Return Value ====
* On success: first item on stack will be "0", next item on the stack will be the decrypted text.
* On failure: first item on stack will be "1", next item on the stack will be the error message.

==== Example ====

<highlight-nsis>
blowfish::decrypt "9I0JMuUoBQjErC3t5hVRLToinZwFTUd7EXwc2u8osV8=" "a strong password"
Pop $0 ; 0 on success, 1 on failure
Pop $1 ; encrypted message on success, error message on failure
</highlight-nsis>

Talk:Why do I get NSIS Error?

2009-11-29T10:52:18Z

Cubique: /* Error launching installer */

'''Bold text'''What does it mean when it says "It may be possible to skip this check using the NCRC
-- it means that if you run the installer as install.exe /NCRC that it will bypass the check for corruption.

== NSIS error and NO real solution!! ==

What a pity that nobody wants to realy get rid of that big issiue!
It's a nuisance and lots of people to whom I recommended OO2 called me and said they are also not able to install OO2. So they switched back to MS-Office.
Is it that difficult to give a clear work around?

The instruction read like the MS knowledge base. NOT real knowledge!
Just try. If you're lucky it'l work. grrrrrrrr
:How about asking for help, like [http://forums.winamp.com/showthread.php?postid=1895971 this guy]? I don't recall seeing you on the forums with details that say "I want a solution" instead of "I want to complain". --[[User:Kichik|kichik]] 04:37, 30 July 2006 (PDT)

== NSIS Error Fix ==

I had the NSIS error ever since I downloaded IE7. I had the Google toolbar with IE6 but it didn't come through on IE7. I reinstalled Google toolbar from this link http://www.java.com/en/download/manual.jsp as well as installed the latest version of JAVA for Windows/online. The error is gone!!!

== Another problem ==

This error appears to me when I open a web link. It happens in different sites (eg. ebay).
What can i do?

== problems installing English software on non English ==

I notice several English programs (second life, EFF TOR package) won't install on my Japanese Windows, a dialog comes up that simply says NSIS error.

And no, I will not go to the forum, I will use other software. Please stop giving people who want to use your software the annoying run around - get it together.
:Well, that's too bad. they simply can't help help you without any details. --[[User:Kichik|kichik]] 03:13, 27 September 2007 (PDT)

== Problem when installer is in folder with cyrillic characters ==

I got the NSIS error when trying to run the installer for some software (notepad++, 7zip). The files had been downloaded by a localized version of Firefox 3.5 to the default download directory. The directory name contained cyrillic characters. Example:

C:\Documents and Settings\User\My Documents\ÐŸÑ€ÐµÐ·ÐµÐ¼Ð°ÑšÐ°

Moving the installer files to a directory containing only ASCII characters helped and I was able to perform the install. This issue looks to be connected to the above (Japanese OS) and seems like a problem with the handling of unicode characters.

This one worked for me. I've copyed files i want to instal from C:\Documents and Settings\xXx\My Documents\DescÄƒrcÄƒri - DescÃ£rcÃ£ri=Downloads - to my desktop and run the installer. it worked for me !

== NSIS error: for executable files ==

I was trying to install programs like bitorrent, emule etc. but all failed bcos of nsis error.I have installed norton internet security in my computer. I disable it then again i tried all failed.but i can install the same files to install from network in my computer. ie executable file in another computer and then try to install from there. Its working fine. when i copy to my computer i cannot install it.
I tried all the way as u told. still i couldnot solve the problm.I even installed new nsis version 2.3. but failed.
Please give me an answer for me.
:Seems like a failing hard drive. Use the forum for further help. The comments section isn't the best place to ask questions. --[[User:Kichik|kichik]] 10:19, 27 November 2007 (PST)

== Drag the installer into the black console window ==

In Windows Vista impossible drag the installer into the black console window.

== It may be the router problem. ==

I had this problem for over two months. Any downloaded file, either "file is corrupt" or "NSIS_Error". I cannot update my any virus database or my windows OS. But after I changed the router, all problems were gone.

== Error launching installer ==

NSIS Installer/Uninstaller will raise this error "Error launching installer" whenever you will launch the installer/uninstaller from an forbidden location (such as C:\, C:\Windows, C:\Program Files, etc).

This is an constraint set on initialization phase of installer/uninstaller and it will always check for this rule. It make sense while you might have a RMDir/Delete instruction in your install/uninstall sections that will harm your system irreversibly.

Just make sure you run this software from a valid location and the installer/uninstaller will load into memory (and run just fine.
