Thank you for the reply! Iv'e just posted this seed as an example. I found it somewhere on the internet. Ofcourse i wouldnt put the real one, to make it visible to everyone

Iv'e been looking for the Electrum kdf, but i couldnt find it... Could you explain how to use these tools, and where can i download them ? Thanks!

Sure, just follow the instructions here: https://github.com/gurnec/decrypt_electrum_seed

If you don't have an Electrum wallet to use the script on, you can create a minimalist one containing this (it's just a JSON text file):

Code:

{"seed": "hGt+sQGFlt7Dhgb3a1kHetNJmlxrMQrZ3D8mheYgVr79ZEGOZK1btAzv44QMwGQ2K+1a/1ct10abxrX56OtvFA==", "use_encryption": true}

If you do need to create your own, the Python script will spit out a bunch of warnings which you can mostly ignore.

FYI the KDF is sha256(sha256("password")), and the encryption is AES-256 in CBC mode with PKCS7 padding. Electrum 1's own mnemonic.py library is included and used if it's an Electrum 1 seed to finish the conversion from seed to mnemonic sentence.
