As I wrote before, there is no such function. There is only the
EVP_PKEY_get_size() which gives you the maximum length the encrypted
data can have for a given key.
If you do not know the length of the ciphertext for the
EVP_PKEY_decrypt() call, you can use the EVP_PKEY_get_size() value,

but have missed one particular point I was looking to clarify.
Suppose I have two private keys: one for a CA named 'foo', and one for a
server, 'bar'. I am using `req` to produce a CSR *from* bar *to* foo, and
