I have a problem with extracting an Privat Key from an old wallet (*.pfx).
In 2011 I convert a Wallet in this (OpenSSL PEM) format. In an old Post i can see the answer, but my programming skill is weak: https://bitcointalk.org/index.php?topic=2631.0
1. I use OpenSSL for receiving the Privat Key:
openssl pkcs12 -in mywallet.pfx -nocerts -out privatekey.pem -nodes
2. Open the *.pem (I used the public key from the Topic above
):-----BEGIN PRIVATE KEY-----

-----END PRIVATE KEY-----
As I understand it, I have to do the following steps :
- computes the sha256 of the key ;
- computes the rmd160 of this hash ;
- add a byte at the begin for the version number (?) ;
- add four bytes at the end for the check sum ;
- encode the result in base58 ;
- computes the sha256 of the key ;
- computes the rmd160 of this hash ;
- add a byte at the begin for the version number (?) ;
- add four bytes at the end for the check sum ;
- encode the result in base58 ;
How can I do that with CMD and Editor? Is this the right way to get the correct bitcoin address?
Thanks for help.
