Can the following function please be added:
int RSA_public_digest(const RSA* key, const EVP_MD *type, unsigned
char *md, unsigned int *len);
which would use “type” to generate a digest over the DER encoding of
the public portion of “key”, and deposit “len” bytes into the
buffer starting at “md”.
A similar function:
int RSA_private_digest() would take the same parameters as
RSA_public_digest(), but for the DER encoding of the private key.
This function is less useful than the first, but is useful for
symmetry in the API and some corner cases.
This could be done quite simply using i2d_RSA_PUBKEY (or i2d_RSAPublicKey
depending on what flavour of public key you want) and then using the
EVP_Digest* functions.
Closing this ticket.

Okay, but why not include a convenience wrapper to do it, whether it's
easy or not?
It seems to be a frequent construct.
