Yes, the basic platform sanity tests, test/sanitytest.c

ECDSA_SIG_free() frees the r and s BIGNUMs before is frees the structure
itself. However, ECDSA_SIG_new() doesn't set r and s to
NULL. It calls zalloc, which sets them to 0x00 bytes.
OK, in most platforms, the NULL pointer is an all 0x00 bytes value, but
it's not
I'm trying to use the EVP interface for signature verification.
However, EVP_DigestVerifyFinal() takes a signature and length as
parameters. While I understand this for RSA, ECDSA signatures have R
and S elements.
Is there a convertor function?
If I must convert by hand, how is it done? In
