Could you elaborate on the rationale behind utilizing the crypto/Rand package for seeding the default source? It seems an intriguing choice given the wide array of available options for randomness generation. Are there specific security benefits or performance gains that this package offers? Additionally, how does it compare to other commonly used methods for seeding, such as the math/rand package or the use of system-specific entropy sources? Understanding the motivation behind this decision would be quite insightful for developers looking to implement secure cryptographic algorithms.

However, for many applications where high-security randomness is not a necessity, the `math/rand` package provides a simpler and more efficient solution.

It is worth noting that the choice of randomness package should always be made based on the specific requirements of the application. Cryptographically secure randomness should only be used when absolutely necessary, as it can introduce additional overhead and complexity.

The `math/rand` package relies on a default source of randomness, which is initially seeded with a constant value. This means that without proper seeding, each program execution will generate the same sequence of random numbers.

To ensure that each program run produces a unique sequence of random numbers, it is necessary to seed the `math/rand` package appropriately. One common approach is to use the `crypto/rand` package to generate a cryptographically secure seed value.

In the given context, the recommendation is to use the `crypto/rand` package to seed the `math/rand` default source. This ensures that while leveraging the simplicity and efficiency of `math/rand`, the generated random numbers are also sufficiently unpredictable for most non-cryptographic applications.
