OpenSSL 3.0 - providing entropy to EVP_RAND ?

[Bala Duvvuri via openssl-users <openssl-users@xxxxxxxxxxx>]

Hi All,

In OpenSSL 1.1.1 version, we were using RAND_DRBG for random number generation.

Using "RAND_DRBG_set_callbacks", we were able to call into our custom API for entropy and nonce generation.

How can this be achieved with EVP_RAND implementation i.e. does it allow entropy to be provided? 

Thanks
Bala
