gpg: public key decryption failed: Bad passphrase

When I  try to decrypt a file using GPG, for which I use "Starksoft.Cryptography.OpenPGP". I got the following error
Starksoft.Cryptography.OpenPGP.GnuPGException: An error occurred while trying to execute command --list-secret-keys.
But when I execute the command through command prompt ">gpg --list-secret-keys", it does list the keys. I could not get "Starksoft.Cryptography.OpenPGP" to work correctly.
Next I tried to get a solution by running the process directly using cmd.exe, which worked perfectly.

>echo Mypasspharse|gpg.exe --passphrase-fd 0 -o "C:\successtest.txt" --decrypt "C:\testfile.txt.gpg"
If Mypassphare contain a character ">" which will get interpreted as std out redirect in windows command prompt. So, passphase will not pass to the next command properly. So make sure you are not using  ">" in Passphase, if you are planning to use command prompt for gpg decryption

autocomplete="off" is not working in chrome

This is one simple issue drove me crazy all afternoon...

I want to ignore the browser autofill option to save the password. Like, sometimes user select the option to save password for the website and Chrome just autofills the password for the user. But, the same machine can be used by multiple users. So you might want to protect the user password, even through user selects to save the password by mistake.

I started searching the solution in Google and I tried, autocomplete="off" for the <input />, it doesn't work, then someone in another post suggested, it will work only if you add autocomplete="off" to the <form /> tag.

Guess what? It didn't work. Since chrome is just ignoring the autocomplete="off" option.

I found a workaround to solve this issue. 

"Chrome autofill the password <input /> tag and the previous <input /> tag. 
So , I added 

<input style="display:none" />
<input type="password" style="display:none" />

It works like a charm. Autofill goes to these <input /> tag, which will not display and the real one works as expected.
