A cryptographically secure pseudorandom number generator ( CSPRNG) or cryptographic pseudorandom number generator ( CPRNG) is a pseudorandom number generator (PRNG) with properties that make it suitable for use in cryptography. It is also referred to as a cryptographic random number generator ( CRNG ).
A 2022 study showed that users of the program aged 50 and above had slower memory loss, or "about 2 fewer years of cognitive aging over a 10-year period compared with non-users", despite the program having nearly no conditions for the sustainability and healthiness of the food products purchased with the coupons (or coupon-credits).
