Comentario

Current patch ignores the random seed generated. ( generate_seed_bcryptgenrandom() does not set it )

Comentario

This works fine on msys2.

Msys1 does not have the bcrypt* support needed, so it still falls back to old time based random sources.

Still targeting to S2_6, since we do msys2 builds from that branch too.
