To paraphrase, It is far from sensible to pick this solution exponent by yourself or come up with any sort of intelligent system as you could possibly for a password (aka Mind wallet) as innumerable these types of procedures are already applied for decades to crack secrets and techniques using several algorithms and Laptop computer software, such as Those people accustomed to crack passwords. As a result, the secret exponent must be generated using a cryptographically-protected pseudo-random amount generator (CSPRNG) such as the WorldWideWeb Consortium (W3C) Cryptography API (disclosure: I'm one among 12 contributors to that spec on Github), so that there's far not as likely a chance that an attacker could predict that value, given that the random bits that make up that number are sourced from a variety of locations from your neighborhood gadget, and from procedures that don't transmit that entropy data online (assuming the software package that you are using is Safe and sound along with a Risk-free CSPRNG). Example Python code:
