I have made a 12-word backup passphrase that according to blockchain.info gives me full control of my funds. However, I did not find out yet how to convert the passphrase into a private key. I tried sha256[passphrase] but this did not produce addresses holding my funds. Nor did I find any wallet that would let me import the passphrase.

The reason I want to do that is because I want extract the "Bitcoin Cash" from my funds.


Any help appreciated.
Kind Regards
