Keys / Addresses

[jackjack]

I've encountered a problem, and it's kinda difficult to investigate more as I still have 40000+ blocks to download.

I made a new Bitcoin wallet (with bitcoin 0.8.1, linux). Obviously it has default keys. Let's take the main one.

Code:

 {
            "addr": "1Co8KFDHnwyuCxfyBWPK1ifRjGiR7AeXDC", 
            "hexsec": "3d423fb2f8b7af14e590230d87ec9067cba3ad29261f829c4f2476ade4278aa0", 
            "label": "", 
            "privkey": "3081d30201010420543d423fb2f8b7af14e590230d87ec9067cba3ad29261f829c4f2476ade4278aa08185308182020101302c06072a8648ce3d0101022100fffffffffffffffffffffffffffffffffffffffffffffffffffffffefffffc2f300604010004010704210279be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798022100fffffffffffffffffffffffffffffffebaaedce6af48a03bbfd25e8cd0364141020101a1240322000302519ca3be493a26d62e96a814388b441bf972f6cf16f07ba49b993f3a12db69", 
            "pubkey": "0302519ca3be493a26d62e96a814388b441bf972f6cf16f07ba49b993f3a12db69", 
            "sec": "5JHGMYGpfoD7HK3jSNrKgRry9yRZGEGJEXBk6w3KPfAdjQRyawb"
        }

This is a dump from Joric's pywallet. 1Co8KFDHnwyuCxfyBWPK1ifRjGiR7AeXDC is what Bitcoin software shows.

The thing is, when I use pywallet (Joric's one, which is up-to-date) to import the private key (here as hexsec or sec) into another wallet, the message it returns to me mentions the address 1MUVkGv8TWjvdJ87VMGoNyhG3NLYE87WQT, and not 1Co8KFDHnwyuCxfyBWPK1ifRjGiR7AeXDC.
If I had access I would have transfered 1 mBTC to each address and tried to retrieve both to see what would happened...

So in the mean time, can anyone tell me what I can do to check where is the error? And can someone check to which address the private key 3d423f... corresponds?
Thanks for any help

Does the pywallet you are using understand compressed keys?

[jackjack]

After a quick look at the wallet file I thought the format didn't change, but yeah, looks like Bitcoin now stores compressed keys.
I left for a while so I don't know much about compressed keys yet, but now you made me look closer at that, everything is clear.
Thanks a lot for the tip, I hope I'll soon post here that everything's fine
