Thanks for reply.

However, i am not conversant with the language so cannot verify on my own.

Is there any other way to know that the SEED is not pre-decided ? Also how to ensure that private keys are built from this SEED only. Theoretically it is possible that the SEED is random but the private key building algorithm is fixed by the programmer. Programmer could have pre-created many Private key-public key-address combinations and the algorithm is generating only those outputs. Thus he can spent from my thus generated addresses.

Am I worrying too much and should go by the reputation of ELECTRUM?
