Short Answer: No, you do not need GPG.
Long Answer: Installation of Bitcoin Core does not require GPG... but it is recommended. GPG is used to verify the cryptographic signature of the compiled binary files... this is to help assure the user that the compiled binary files that they downloaded are indeed legitimate (and not fakes/possibly malware). Note that Bitcoin Core will work fine without GPG installed, but the end user cannot be 100% sure they used a legitimate binary installer unless they verified it with GPG first.
Pywallet does not have any such facility. It is written and distrbuted in a scripting language (Python) so you can inspect all the code by simply opening the .py script in a text editor.
To know if you have it installed correctly, you run it and see if it works. Generally something like "python scriptname.py --help" or "python scriptname.py --version" to see the script help and/or version number respectively will tell you if you have Python, the script and any dependencies installed and working OK.

I was reading about proper installation of bitcoin core and ran into the necessity of installing GPG on that computer ( for using and storing trusted keys.......)
Does Jack Jack proper operation require GPG installation? Is it a given inherent part already built into the program? How do I know if I have it installed completely and works properly?

PyWallet works fine as it is... you just need to make sure that you have the appropriate password to be able to decrypt the private keys.
If the wallet is encrypted, there are no modifications that can be made that will allow you to view the private key data without the password. Do you have the wallet password?

I'm sorry, I still don't understand exactly what the problem is... are you saying that PyWallet is NOT giving you the address/private key data output when you try to use the dumpwallet command?
If so, what output and/or errors are you getting when you try to execute PyWallet?
If so, what output and/or errors are you getting when you try to execute PyWallet?
can you develop latest pywallet to give address/private key data output (decrypted key) if yes please contact me on [email protected]
The output you are getting is from an "encrypted" wallet... it has a password set... That is why you are getting:
If you know what the password is, you can specify it when running pywallet (or enter it when it prompts you).
If you aren't 100% sure what the password is, but you have some idea of what the password might be (ie. number of characters in the password and possible combinations of words/letters/symbols etc) then you might be able to use something like btcrecover or hashcat to try and bruteforce the password.
If you have no idea what the password is, then you have ZERO chance of bruteforcing the password and any bitcoins in that wallet are effectively "lost"
...
"encrypted_privkey": "f60916cd8c7bef5c62e60eb030c821c3e3ccdad1c07aefbfb28abd075492a4fe90e168ef9745b9f f692a79032490c2fb",

Without the wallet password, you will not be able to access the private keys!"encrypted_privkey": "f60916cd8c7bef5c62e60eb030c821c3e3ccdad1c07aefbfb28abd075492a4fe90e168ef9745b9f f692a79032490c2fb",

RE: documentation about key encryption:
See the comment at the top of crypter.h:
The way I think of it: Take the passphrase and salt and SHA512-hash them nDerivationIterations times. That gets you an encryption key and initialization vector.
Use those to AES-256-decrypt the encrypted_key master key.
Now you can AES-256-decrypt the private keys, using the master key as the key and the (double-sha256-hash) PUBLIC part of the keypair as the initialization vector.
The "SHA-512-hash them a bunch of times" is actually done by the OpenSSL EVP_BytesToKey routine-- documentation for that is here: http://www.openssl.org/docs/crypto/EVP_BytesToKey.html
I'd been wondering about this for awhile. Thanks for the info.See the comment at the top of crypter.h:

I have several time try openssl AES-256-decrypt from encrypted_privkey; which i have find find from the pywallet.

question about "hexsec" and "secret"
consider this dump of an unencrypted wallet: (don't worry, I won't store bitcoins at these keys, I'm just experimenting)
Why are "secret" and "hexsec" only 16 bytes?
This is the same key after loading the wallet with bitcoin 0.9 and encrypting it (and decrypting again with pywallet)
It almost looks like the first version was just cut off in the middle.
Another question: Is there any documentation about the various elements of the json that is produced with pywallet?
* For example what is the meaning of the "pool" array, its repeating all the addresses but without their keys but seems to contain additional info, what is the rationale behind structuring it that way and not just put all info about a key into one object?
* what is the empty ckey array at the beginning of the dump?

It indeed cut the private key in the middle because of a stupid error. Thank you so much for finding that. It's now fixed.

However if it is not pywallet; please give me your script as following email id: [email protected]
I'm sorry, I still don't understand exactly what the problem is... are you saying that PyWallet is NOT giving you the address/private key data output when you try to use the dumpwallet command?
If so, what output and/or errors are you getting when you try to execute PyWallet?

Donation address for pywallet is in the about page of the WUI, it's 1AQDfx22pKGgXnUZFL1e4UKos3QqvRzNh5. Thank you for making me mention it.
No problem.
Coins sent https://blockchain.info/tx/02f632bea4b192f899108b3706e001e828eed546eac0b19321154278c034c7c3 Wait nobody has ever donated? WTF? Soapbox mode engaged.
Public service announcement. If pywallet has made your life easier (and you know it has), then show some support by sending some coins. Come on this is a great tools to crack the byzantine mess that is wallet.dat. Eventually the wallet will move to leveldb which is going to require a significant rewrite of pywallet. Hint: developers tend not to continually support projects they see no support from the community.
BTW if you are reading this PSA, in the "Pywallet: manage your wallets/addresses/keys/tx's" thread, well the odds are it probably applies to you (otherwise you wouldn't be here).
hexsec is the hexadecimal private key (you must have made a mistake with your copypastings)
secret is hexsec alone if uncompressed address, and hexsec+'\x01' if compressed address
sec is WIF formatted private key
secret is hexsec alone if uncompressed address, and hexsec+'\x01' if compressed address
sec is WIF formatted private key
Weird that is not what I am getting.
Here is a unmodifed copy & paste of one key (a heads up to scammers, I removed this unused key from my keypool so nothing to steal)

This is on pywallet running on Windows, using a wallet exported from v0.8.3 client in case that somehow makes a difference.

Maybe I don't understand, but it's already what is happening when you dump an encrypted wallet without providing the passphrase.
DOH, I never tried. I assumed passphrase was required for encrypted wallets. Yeah it does exactly that and that is exactly what I was looking for. I feel a little stupid that I needed assistance with that, but still glad I asked. Pure awesome.

Pywallet is very old and the wallet.dat file format has changed since Pywallet was last updated (2014).
It looks like the script does not handle some of the new data fields that are now included in the wallet.dat file. It should theoretically be possible to modify the script to either handle or ignore the unknown fields.
If you just want to dump the file and don't care about making a "valid" wallet.dat... you can edit the pywallet.py file:
Change Line #2111 from:
Then on Line #2502, change:
The script will still spit out a whole heap of garbage like this:

You have forgotten to add the --dumpwallet option to your command. You need to use that and --dumpwithbalance. Try this:
Code:
sudo python2.7 ./pywallet.py --dumpwallet --dumpwithbalance --datadir=/path/to/wallet/ --wallet=wallet.dat
and replace the /path/to/wallet/ with your actual path etc
When i do
Code:
sudo python2.7 ./pywallet.py --dumpwithbalance --datadir=/path/to/wallet/ --wallet=wallet.dat
It just prints out the readme. What am i doing wrong? I'm trying to dump private key from wallet.dat file is corrupted and no longer access but shows "Warning:root:pycrypto or libssl not found, decryption may be slow"
It's not a problem. It's just a warning. You can ignore it.
