2 a custom randombytes must implement:
4 void ED25519_FN(ed25519_randombytes_unsafe) (void *p, size_t len);
6 ed25519_randombytes_unsafe is used by the batch verification function
7 to create random scalars
9 #include <sodium/randombytes.h>
11 void ED25519_FN(ed25519_randombytes_unsafe
) (void *p
, size_t len
)
