So I tore apart the bitcoin2john python script and saw how it formats the output mode for JTR.  It looks like the public key on the wallet.dat file has a public key size of 130, while the working wallet.dat file is 66.  Does anyone know if this is just the inability of oclhashcat to parse this or is this key messed up.

I'm trying to recover a wallet from a few years ago currently running on the client v.4.7.4. The wallet is encrypted, however I know enough of the password to attempt a brute force.  However when I dump the password hash, the hash comes out 64 bytes longer than the standard.  Was this a different formated hash on this version(I know v4 had issues that were patched in v5), or is my wallet.dat file corrupt?
