Avoid being a driveby victim — Stop convenient access to your data

More than 15 years ago Motorola's Information Protection Chief called his forward to our book, Cryptography Decrypted, e Everything —writing about eEverything good along with eEverything bad. (Noticeably) more true now than then.

To help deter attack we developed

DoCrypt Crypto Tools

the current US & world-wide standard and DES (previous standard) for
     message & file encryption –using password based or keyStore keys.

 Crypto fingerPrinter for data authenticity and integrity

  Logon–Password Manager stores web logon & password data

  Key Store (aka keychain, ring...)  One of cryptography's main benefits is
      one (1) key can protect all your other keys.

· Compare security of computer-made keys to human-made keys

   · Evaluating vulnerabilities


· Compare secret key strengths ( DES–56,  AES–128, 256 )

   · How encryption can be corrupted

4 computerized preComputer methods demonstrate / explain method and key,
   –and how they evolved to AES.

   (more in program)

key creation & storage is done on your computer because...

...a computer that makes or shares your keys → can use your keys like you can.

*Even though one can always add more security, encryption is the best and

most simple way to protect your and our society's data from bad actors.
