Hello software developers,
Please check your code to ensure you're not making one of the following mistakes related to cryptography.
- 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
