			This plug-in uses an implementation of Blowfish that is broken on little-endian machines. This means that it will not be interoperable with other implementations of Blowfish, such as those in PHP and Java. For more information and a fix, [http://stackoverflow.com/questions/2152017/blowfish-encrypted-messages-between-nsis-and-php see this post].

== 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>
