Hello jNizM,

that's exactly what I wanted. I use from Time to Time an Online Service to generate the MD5 Hash String, but Offline it ensures a better sense of Security for me.
Its very useful, thank You!

Good Morning,

Thanks you very much, your calc works very well and I could verify two raspberry pi image files that I had SHA256 checksum

Congrats

.Ramon.

Hello jNizM,

really useful program with nice UI. Thank you for making it!!

I made a small improvement:
If you add following lines in the "WINDOW EVENTS" section, a droped file is added in the File-tab.

Code: Select all

;Drag&Drop Files to Input GUI
GuiDropFiles:
Loop %A_GuiEvent%, 1 					;1 = Loop folders and files
	If InStr( A_LoopFileAttrib, "D" )		;D==Folder -> exit
	 {
		MsgBox, Folder not accepted. `n %A_GuiEvent%
	 }
	Else
	 {
		GuiControl,, HASH_FILE, %A_GuiEvent%
		FileGetSize, FILE_SIZE, %A_GuiEvent%
		GuiControl,, HASH_FILE_SIZE, % "File Size: " StrFormatByteSizeEx(FILE_SIZE, 0x1)
	 }
return

Is it possible to hide a string within a script by using HashCalc? The purpose would be to make it more difficult for the average user to obtain the source code.
Is there a way to un-hash the string while the script is running? A guess that would be a function call?
Forgive all my questions, I'm trying to learn about cryptography.
For example....

Code: Select all

; Hashed String using SHA-256
;msgbox, This is my first message
msgbox, bb0653dcf092d83846740ede19c2b6bd9b785070765fe4d7059c119d71f25632
return

Encryption is a two-way function. What is encrypted can be decrypted with the proper key. Hashing, however, is a one-way function that scrambles plain text to produce a unique message digest. With a properly designed algorithm, there is no way to reverse the hashing process to reveal the original password.

Looks pretty good!
I'm sure I can find a use for that someday. Saving it now.
Thanks for sharing

I don't need the form interface, just copy the result of converting this lhabceq6jdr to sha256 to the paste board.How do I modify the AutoHotkey script?

AutoHotkey V1

Thanks!
