Hello software developers,

Please check your code to ensure you're not making one of the following mistakes related to cryptography.

I. General Mistakes

• Writing your own home-grown cryptography primitives (For example: Mifare Classic)
  • Exception: For the sake of learning, but don't deploy it in production.
• Using a fast hash function (e.g. MD5, SHA256) for storing passwords. Use bcrypt instead.
• Not using a cryptographically secure random number generator

Minecraft Ultimate Tool Set

Requires creative mode or operator power on a multiplayer server. On a single player game (survival or hardcore), you will need "cheats" enabled to move into creative mode. Don't forget to leave creative mode when done.

These items might be stupid. Be prepared to repair the country-side.
