AssertionError: Bad private key

[ikndevs]

I'm trying to get jeeq to work for the first time.

I've generated a throw away address with bitcoind:

$ bitcoind getnewaddress
1k2LVG8jXmRU1Hxjto8UFuKbfYPCJT9oE
$ bitcoind dumpprivkey 1k2LVG8jXmRU1Hxjto8UFuKbfYPCJT9oE
L3BsiJ5LzwrKF7ZLGZBjhaSqMzAMFi4fBBC7RnxRW7xj9kmakGiR
$ bitcoind validateaddress 1k2LVG8jXmRU1Hxjto8UFuKbfYPCJT9oE
{
    "isvalid" : true,
    "address" : "1k2LVG8jXmRU1Hxjto8UFuKbfYPCJT9oE",
    "ismine" : true,
    "isscript" : false,
    "pubkey" : "038bd796cc06e1c11c8adc5aba0df5a9344b935c5b9165405d63461e79078c7aef",
    "iscompressed" : true,
    "account" : ""
}

Encryption seems to work OK:

$ ./jeeq.py -e -i ./test.txt -o ./test.enc -k 038bd796cc06e1c11c8adc5aba0df5a9344b935c5b9165405d63461e79078c7aef

Encrypted message to 1k2LVG8jXmRU1Hxjto8UFuKbfYPCJT9oE:
amoAAAICzAN+M/+48D5sDc+xyEp+LW/Mhy+dv2xbfCY6ZFAyUcIyHgN1geIlcapxIQhzp+5Uug8Xl8X9Re7uz+7qtg90E8b6WA==

But decryption fails:

$ ./jeeq.py -d -i ./test.enc -o ./test.dec -k L3BsiJ5LzwrKF7ZLGZBjhaSqMzAMFi4fBBC7RnxRW7xj9kmakGiR
Traceback (most recent call last):
  File "./jeeq.py", line 466, in <module>
    assert len(private_key)==32, 'Bad private key'
AssertionError: Bad private key

I vaguely feel that I should be using a 'raw' private key in some form, rather than the base58 encoded version.

Is this this case?

If so, how would I get a raw private key from bitcoind?

Indeed, you need to use the hexadecimal private key
For example, for the private key L3BsiJ5LzwrKF7ZLGZBjhaSqMzAMFi4fBBC7RnxRW7xj9kmakGiR, the hex private key is B2147BE63B72873F518C00FEC4C10F1A3E8F7A0153CC92C85948F0BF52942CDC (taken from https://www.bitaddress.org)
Please confirm it works
I'll change the error message, thanks for the input

[ikndevs]

Thanks, that fixed it.

[ikndevs]

Is there anyway to get the hex representation of private keys without pasting them into an untrusted web page, that could be logging/stealing my private keys?

[jackjack-jj]

I can't test from here but try DecodeBase58Check (already inside the file, line 222)
I think you'll get a trailing \x01 (that means the key is compressed), just remove it

[ikndevs]

The indentation looks a little suspect on

assert len(private_key)==32, 'Bad private key, you must give it in hexadecimal, or base58check'

I may have messed it up with my editor, sorry.
