pycrypto or libssl not found, decryption may be slow My wallet.dat file is corrupted and everytime i try to run Wallet QT client will shut down as unexpected error and i have no longer access at my wallet on this way.

I have tried to dump private keys through pywallet but everytime i execute commands it shows pywallet or libssl not found...

 

Actually i don't have much experience with this, Downloaded openssl and pycrypto then extracted both files to C:\Python27 , im doing this wrong if yes please help me to setup.
Your image shows two messages:

There is a message


  ERROR:root:Couldn't open wallet.dat/main


It suggests you should close Bitcoin if it is already running. I would use Windows' task-manager to see if bitcoin-qt, bitcoind etc are running (Ctrl+Alt+Del in Windows-10 should bring up a menu from which you can select task-manager). You can close those processes from task manager if necessary.

Since your screenshot shows a second attempt without this error, it looks like you shut down Botcoin-qt OK and the command completed OK.



and 


  WARNING:root:pycrypto or libssl not found, decryption may be slow


This is just a warning, it doesn't mean that the command won't work, just that it may take longer than normal.

The message suggests pywallet will use slow internal cryptographic functions if it doesn't have access to a fast external library of cryptographic functions.



So your wallet.txt file should show you the information you wanted to extract.
