Just how that s is selected also matters immensely with regard to its cryptographic protection. Basically, it is not recommended to select this mystery exponent yourself or come up with any sort of intelligent process as you may for any password (aka brain wallet) as many these types of techniques have already been employed for decades to crack strategies employing a variety of algorithms and Laptop software package, for instance All those accustomed to crack passwords. For that reason, The key exponent should be generated using a cryptographically-secure pseudo-random number generator (CSPRNG) including the WorldWideWeb Consortium (W3C) Cryptography API (disclosure: I am certainly one of 12 contributors to that spec on Github), so that there's significantly less likely an opportunity that an attacker could predict that value, given that the random bits which make up that number are sourced from numerous places from your neighborhood machine, and from procedures that don't transmit that entropy facts on the net (assuming the program you happen to be utilizing is Harmless in addition to a safe CSPRNG). Case in point Python code:
