42 A context I<ctx> without a pre-loaded key cannot be used with this function.
44 treatment of the input to EVP_PKEY_verify() may be pre-determined, and in that
52 Passing the message is supported both in a one-shot fashion using
56 length, such as ED25519, RSA-SHA256 and similar.
74 EVP_PKEY_verify() is a one-shot function that performs the same thing as
100 to produce the digest internally, and while RSA-SHA256 can be expected to
107 L<EVP_PKEY_CTX_set_rsa_padding(3)> and similar others), while an RSA-SHA256
108 implementation usually has these details pre-set and immutable.
114 words, it's not possible to specify a I<ctx> pre-loaded with an RSA pkey, or
116 functionality of RSA-SHA256.  If combining algorithms in that manner is
