+EVP_KDF_KB - The Key-Based EVP_KDF implementation
+
+=head1 DESCRIPTION
+
+The EVP_KDF_KB algorithm implements the Key-Based key derivation function
+(KBKDF).  KBKDF derives a key from repeated application of a keyed MAC to an
+input secret (and other optional values).
+
+=head2 Numeric identity
+
+B<EVP_KDF_KB> is the numeric identity for this implementation; it can be used with the

+
+The supported controls are:
+
+=over 4
+
+=item B<EVP_KDF_CTRL_SET_KB_MODE>
+
+This control expects one argument: C<int mode>
+
+Sets the mode for the KBKDF operation. There are two supported modes:
+
+=over 4
+
+=item B<EVP_KDF_KB_MODE_COUNTER>
+
+The counter mode of KBKDF should be used. This is the default.
+
+=item B<EVP_KDF_KB_MODE_FEEDBACK>
+
+The feedback mode of KBKDF should be used.
+
+=back
+
+=item B<EVP_KDF_CTRL_SET_KB_MAC_TYPE>
+
+This control expects one argument: C<int mac_type>
+
+Sets the mac type for the KBKDF operation. There are two supported mac types:

+=over 4
+
+=item B<EVP_KDF_KB_MAC_TYPE_HMAC>
+
+The HMAC with the digest set by B<EVP_KDF_CTRL_SET_MD> should be used as the mac.
+
+=item B<EVP_KDF_KB_MAC_TYPE_CMAC>
+
+The CMAC with the cipher set by B<EVP_KDF_CTRL_SET_CIPHER> should be used as the mac.

+
+These controls work as described in L<EVP_KDF_CTX(3)/CONTROLS>.
+
+=item B<EVP_KDF_CTRL_SET_KB_INFO>
+
+This control expects two arguments: C<unsigned char *info>, C<size_t infolen>
+
+=item B<EVP_KDF_CTRL_SET_KB_SEED>
+
+This control expects two arguments: C<unsigned char *seed>, C<size_t seedlen>
+
+It is used only in the feedback mode and the length must be the same
+as the block length of the cipher in CMAC or the size of the digest in HMAC.
+
+=back
+
+The controls B<EVP_KDF_CTRL_SET_KEY>, B<EVP_KDF_CTRL_SET_SALT>,
+B<EVP_KDF_CTRL_SET_KB_INFO>, and B<EVP_KDF_CTRL_SET_KB_SEED> 
+correspond to KI, Label, Context, and IV (respectively) in SP800-108.
+As in that document, salt, info, and seed are optional and may be
+omitted.
+
+Depending on whether mac is CMAC or HMAC, either digest or cipher is
+required (respectively) and the other is unused.
+
+=head1 NOTES
+
+A context for KBKDF can be obtained by calling:
+
+ EVP_KDF_CTX *kctx = EVP_KDF_CTX_new_id(EVP_KDF_KB);
+
+The output length of an KBKDF is specified via the C<keylen>
+parameter to the L<EVP_KDF_derive(3)> function.
+
+Note that currently OpenSSL only implements counter and feedback modes.  Other
+variants may be supported in the future.

+
+=head1 DESCRIPTION
+
+Support for computing the B<KRB5KDF> KDF through the B<EVP_KDF> API.
+
+The B<EVP_KDF_KRB5KDF> algorithm implements the key derivation function defined
+in RFC 3961, section 5.1 and is used by Krb5 to derive session keys.
+Three inputs are required to perform key derivation: a cipher, (for example
+AES-128-CBC), the initial key, and a constant.
+
+=head2 Numeric identity
+
+B<EVP_KDF_KRB5KDF> is the numeric identity for this implementation; it can be used with the
+EVP_KDF_CTX_new_id() function.
+

+
+These controls work as described in L<EVP_KDF_CTX(3)/CONTROLS>.
+
+=item B<EVP_KDF_CTRL_SET_KRB5KDF_CONSTANT>
+
+This control expects two arguments: C<unsigned char *constant>, C<size_t constantlen>
+
+This control sets the I<constant> value for the KDF.
+If a value is already set, the contents are replaced.
+
+=back
+
+
+=head1 NOTES
+
+A context for KRB5KDF can be obtained by calling:
+
+ EVP_KDF_CTX *kctx = EVP_KDF_CTX_new_id(EVP_KDF_KRB5KDF);
+
+The output length of the KRB5KDF derivation is specified via the I<keylen>
+parameter to the L<EVP_KDF_derive(3)> function, and MUST match the key
+length for the chosen cipher or an error is returned. Moreover the
+I<constant>'s length must not exceed the block size of the cipher.
+Since the KRB5KDF output length depends on the chosen cipher, calling
+L<EVP_KDF_size()> to obtain the requisite length returns the correct length
+only after the cipher is set. Prior to that B<EVP_MAX_KEY_LENGTH> is returned.
+The caller must allocate a buffer of the correct length for the chosen
+cipher, and pass that buffer to the L<EVP_KDF_derive(3)> function along
+with that length.
+
+=head1 EXAMPLES
+
+This example derives a key using the AES-128-CBC cipher:
+
+ EVP_KDF_CTX *kctx;
+ unsigned char key[16] = "01234...";
+ unsigned char constant[] = "I'm a constant";
+ unsigned char out[16];

+=head1 NOTES
+
+A context for SSKDF can be obtained by calling:
+
+EVP_KDF_CTX *kctx = EVP_KDF_CTX_new_id(EVP_KDF_SS);
+
+The output length of an SSKDF is specified via the C<keylen>
+parameter to the L<EVP_KDF_derive(3)> function.
+
+=head1 EXAMPLE
+
+This example derives 10 bytes using H(x) = SHA-256, with the secret key "secret"
+and fixedinfo value "label":
+
+  EVP_KDF_CTX *kctx;
+  unsigned char out[10];
+
+  kctx = EVP_KDF_CTX_new_id(EVP_KDF_SS);
+
+  if (EVP_KDF_ctrl(kctx, EVP_KDF_CTRL_SET_MD, EVP_sha256()) <= 0) {
+      error("EVP_KDF_CTRL_SET_MD");
+  }
+  if (EVP_KDF_ctrl(kctx, EVP_KDF_CTRL_SET_KEY, "secret", (size_t)6) <= 0) {
+      error("EVP_KDF_CTRL_SET_KEY");
+  }
