Security Notes

安全注意事项

  • Always use cryptographically secure random generators
  • Never use 
    rand()
    or similar pseudo-random functions
  • Use appropriate length (min 16 for passwords, 32 for keys)
  • Store hashes, never store plain text
  • Use unique salts for each password
  • 始终使用加密安全的随机生成器
  • 切勿使用
    rand()
    或类似的伪随机函数
  • 使用合适的长度（密码至少16位，密钥至少32位）
  • 存储哈希值，绝不存储明文
  • 为每个密码使用唯一的盐值
