-=head1 NAME
-
-EVP_PKEY_derive_init, EVP_PKEY_derive_set_peer, EVP_PKEY_derive - derive public
-key algorithm shared secret.
-
-=head1 SYNOPSIS
-
- #include <openssl/evp.h>
-
- int EVP_PKEY_derive_init(EVP_PKEY_CTX *ctx);
- int EVP_PKEY_derive_set_peer(EVP_PKEY_CTX *ctx, EVP_PKEY *peer);
- int EVP_PKEY_derive(EVP_PKEY_CTX *ctx, unsigned char *key, size_t *keylen);
-
-=head1 DESCRIPTION
-
-The EVP_PKEY_derive_init() function initializes a public key algorithm
-context using key B<pkey> for shared secret derivation.
-
-The EVP_PKEY_derive_set_peer() function sets the peer key: this will normally
-be a public key.
-
-The EVP_PKEY_derive() derives a shared secret using B<ctx>.
-If B<key> is B<NULL> then the maximum size of the output buffer is written to
-the B<keylen> parameter. If B<key> is not B<NULL> then before the call the
-B<keylen> parameter should contain the length of the B<key> buffer, if the call
-is successful the shared secret is written to B<key> and the amount of data
-written to B<keylen>.
-
-=head1 NOTES
-
-After the call to EVP_PKEY_derive_init() algorithm specific control
-operations can be performed to set any appropriate parameters for the
-operation.
-
-The function EVP_PKEY_derive() can be called more than once on the same
-context if several operations are performed using the same parameters.
-
-=head1 RETURN VALUES
-
-EVP_PKEY_derive_init() and EVP_PKEY_derive() return 1 for success and 0
-or a negative value for failure. In particular a return value of -2
-indicates the operation is not supported by the public key algorithm.
-
-=head1 EXAMPLE
-
-Derive shared secret (for example DH or EC keys):
-
- #include <openssl/evp.h>
- #include <openssl/rsa.h>
-
- EVP_PKEY_CTX *ctx;
- unsigned char *skey;
- size_t skeylen;
- EVP_PKEY *pkey, *peerkey;
- /* NB: assumes pkey, peerkey have been already set up */
-
- ctx = EVP_PKEY_CTX_new(pkey);
- if (!ctx)
-        /* Error occurred */
- if (EVP_PKEY_derive_init(ctx) <= 0)
-        /* Error */
- if (EVP_PKEY_derive_set_peer(ctx, peerkey) <= 0)
-        /* Error */
-
- /* Determine buffer length */
- if (EVP_PKEY_derive(ctx, NULL, &skeylen) <= 0)
-        /* Error */
-
- skey = malloc(skeylen);
-
- if (!skey)
-        /* malloc failure */
-
- if (EVP_PKEY_derive(ctx, skey, &skeylen) <= 0)
-        /* Error */
-
- /* Shared secret is skey bytes written to buffer skey */
