Governor Deal, veto SB 315 because white hat security researchers should be thanked not jailed!
Rietta corporate letter to Governor Nathan Deal asking him to VETO GA SB 315, busting four myths that do not match up with the realities of Internet security. White hat security researchers, the good Samaritans of cybersecurity, should be thanked not prosecuted!
Panera Bread Story Is An Example of Why Governor Deal Should Veto SB 315
Panera Bread exposed millions of customer records publicly online through shear technical negligence. I call on Georgia Governor Nathan Deal to VETO SB 315 to protect independent security threat researchers who bring these issues to the light of day so that the public may be protected.

As big companies buy cybersecurity insurance rather than fix fundamental security problems, Georgia clears the way for them to press charges or bring civil lawsuits against Good Samaritan researchers.
Georgia SB 315 anti-hacking law dangerously misses the mark of protecting people, making us all less safe
If Georgia SB 315 becomes law, computer security experts will stop reporting vulnerabilities in good faith because doing so could lead to their criminal prosecution under dangerously broad anti-hacking law.

It is not just one iPhone, the FBI wants a future where it is impractical to deploy strong encryption without key escrow
The FBI wants a future where it is illegal or impractical to deploy strong encryption without key escrow, which is a key backup system that is insecure at scale. Data breach risks will increase as our devices become less secure.
Use bcrypt or scrypt instead of SHA* for your passwords, please!
TL;DR; SHA1, SHA256, and SHA512 are all *fast hashes* and are bad for passwords. BCRYPT is a *slow hash* and is good for passwords. Always use slow hashes, never fast hashes.
