+
+=head1 DESCRIPTION
+
+The EVP KDF routines are a high level interface to Key Derivation Function
+algorithms and should be used instead of algorithm-specific functions.
+
+After creating a C<EVP_KDF_CTX> for the required algorithm using
+EVP_KDF_CTX_new_id(), inputs to the algorithm are supplied using calls to
+EVP_KDF_ctrl(), EVP_KDF_vctrl() or EVP_KDF_ctrl_str() before calling
+EVP_KDF_derive() to derive the key.
+
+=head2 Types
+
+B<EVP_KDF_CTX> is a context type that holds the algorithm inputs.
+
+=head2 Context manipulation functions
+
+EVP_KDF_CTX_new_id() creates a KDF context for the algorithm identified by the
+specified NID.
+
+EVP_KDF_CTX_free() frees up the context C<ctx>.  If C<ctx> is C<NULL>, nothing
+is done.
+
+=head2 Computing functions
+
+EVP_KDF_reset() resets the context to the default state as if the context
+had just been created.
+
+EVP_KDF_ctrl() is used to provide inputs to the KDF algorithm prior to
+EVP_KDF_derive() being called.  The inputs that may be provided will vary
+depending on the KDF algorithm or its implementation.  This functions takes
+variable arguments, the exact expected arguments depend on C<cmd>.
+See L</CONTROLS> below for a description of standard controls.
+
+EVP_KDF_vctrl() is the variant of EVP_KDF_ctrl() that takes a C<va_list>
+argument instead of variadic arguments.
+
+EVP_KDF_ctrl_str() allows an application to send an algorithm specific control
+operation to a context C<ctx> in string form.  This is intended to be used for
+options specified on the command line or in text files.
+
+EVP_KDF_size() returns the output size if the algorithm produces a fixed amount
+of output and C<SIZE_MAX> otherwise.  If an error occurs then 0 is returned.
+For some algorithms an error may result if input parameters necessary to
+calculate a fixed output size have not yet been supplied.
+
+EVP_KDF_derive() derives C<keylen> bytes of key material and places it in the
+C<key> buffer.  If the algorithm produces a fixed amount of output then an
+error will occur unless the C<keylen> parameter is equal to that output size,
+as returned by EVP_KDF_size().
+
+=head1 CONTROLS
+
+The standard controls are:
+
+=over 4
+
+=item B<EVP_KDF_CTRL_SET_PASS>
+
+This control expects two arguments: C<unsigned char *pass>, C<size_t passlen>
+
+Some KDF implementations require a password.  For those KDF implementations
+that support it, this control sets the password.
+
+EVP_KDF_ctrl_str() takes two type strings for this control:
+
+=over 4
+
+=item "pass"
+
+The value string is used as is.
+
+=item "hexpass"
+
+The value string is expected to be a hexadecimal number, which will be
+decoded before being passed on as the control value.
+
+=back
+
+=item B<EVP_KDF_CTRL_SET_SALT>
+
+This control expects two arguments: C<unsigned char *salt>, C<size_t saltlen>
+
+Some KDF implementations can take a salt.  For those KDF implementations that
+support it, this control sets the salt.
+
+The default value, if any, is implementation dependent.
+
+EVP_KDF_ctrl_str() takes two type strings for this control:

+
+=item B<EVP_KDF_CTRL_SET_ITER>
+
+This control expects one argument: C<int iter>
+
+Some KDF implementations require an iteration count. For those KDF implementations that support it, this control sets the iteration count.
+
+The default value, if any, is implementation dependent.
+
+EVP_KDF_ctrl_str() type string: "iter"
+
+The value string is expected to be a decimal number.
+
+=item B<EVP_KDF_CTRL_SET_MD>
+
+This control expects one argument: C<EVP_MD *md>
+
+For MAC implementations that use a message digest as an underlying computation
+algorithm, this control set what the digest algorithm should be.
+
+EVP_KDF_ctrl_str() type string: "md"
+
+The value string is expected to be the name of a digest.
+
+=item B<EVP_KDF_CTRL_SET_KEY>
+
+This control expects two arguments: C<unsigned char *key>, C<size_t keylen>
+
+Some KDF implementations require a key.  For those KDF implementations that
+support it, this control sets the key.
+
+EVP_KDF_ctrl_str() takes two type strings for this control:
+
+=over 4
+
+=item "key"
+
+The value string is used as is.
+
+=item "hexkey"
+
+The value string is expected to be a hexadecimal number, which will be
+decoded before being passed on as the control value.
+
+=back
+
+=item B<EVP_KDF_CTRL_SET_MAXMEM_BYTES>
+
+This control expects one argument: C<uint64_t maxmem_bytes>
+
+Memory-hard password-based KDF algorithms, such as scrypt, use an amount of
+memory that depends on the load factors provided as input.  For those KDF
+implementations that support it, this control sets an upper limit on the amount
+of memory that may be consumed while performing a key derivation.  If this
+memory usage limit is exceeded because the load factors are chosen too high,
+the key derivation will fail.
+
+The default value is implementation dependent.
+
+EVP_KDF_ctrl_str() type string: "maxmem_bytes"
+
+The value string is expected to be a decimal number.
+
+=back
+
+=head1 RETURN VALUES
+
+EVP_KDF_CTX_new_id() returns either the newly allocated C<EVP_KDF_CTX>
+structure or C<NULL> if an error occurred.
+
+EVP_KDF_CTX_free() and EVP_KDF_reset() do not return a value.
+
+EVP_KDF_size() returns the output size.  C<SIZE_MAX> is returned to indicate
+that the algorithm produces a variable amount of output; 0 to indicate failure.
+
+The remaining functions 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 KDF algorithm.

+=head1 NAME
+
+EVP_KDF_HKDF - The HKDF EVP_KDF implementation
+
+=head1 DESCRIPTION
+
+Support for computing the B<HKDF> KDF through the B<EVP_KDF> API.
+
+The EVP_KDF_HKDF algorithm implements the HKDF key derivation function.
+HKDF follows the "extract-then-expand" paradigm, where the KDF logically
+consists of two modules. The first stage takes the input keying material
+and "extracts" from it a fixed-length pseudorandom key K. The second stage
+"expands" the key K into several additional pseudorandom keys (the output
+of the KDF).
+
+=head2 Numeric identity
+
+B<EVP_KDF_HKDF> is the numeric identity for this implementation; it
+can be used with the EVP_KDF_CTX_new_id() function.
+
+=head2 Supported controls
+
+The supported controls are:
+
+=over 4
+
+=item B<EVP_KDF_CTRL_SET_SALT>
+
+=item B<EVP_KDF_CTRL_SET_MD>
+
+=item B<EVP_KDF_CTRL_SET_KEY>
+
+These controls work as described in L<EVP_KDF_CTX(3)/CONTROLS>.
+
+=item B<EVP_KDF_CTRL_RESET_HKDF_INFO>
+
+This control does not expect any arguments.
+
+Resets the context info buffer to zero length.
+
+=item B<EVP_KDF_CTRL_ADD_HKDF_INFO>
+
+This control expects two arguments: C<unsigned char *info>, C<size_t infolen>
+
+Sets the info value to the first B<infolen> bytes of the buffer B<info>.  If a
+value is already set, the contents of the buffer are appended to the existing
+value.
+
+The total length of the context info buffer cannot exceed 1024 bytes;
+this should be more than enough for any normal use of HKDF.
+
+EVP_KDF_ctrl_str() takes two type strings for this control:
+
+=over 4
+
+=item "info"
+
+The value string is used as is.
+
+=item "hexinfo"
+
+The value string is expected to be a hexadecimal number, which will be
+decoded before being passed on as the control value.
+
+=back
+
+=item B<EVP_KDF_CTRL_SET_HKDF_MODE>
+
+This control expects one argument: C<int mode>
+
+Sets the mode for the HKDF operation. There are three modes that are currently
+defined:
+
+=over 4
+
+=item EVP_KDF_HKDF_MODE_EXTRACT_AND_EXPAND
+
+This is the default mode.  Calling L<EVP_KDF_derive(3)> on an EVP_KDF_CTX set
+up for HKDF will perform an extract followed by an expand operation in one go.
+The derived key returned will be the result after the expand operation. The
+intermediate fixed-length pseudorandom key K is not returned.
+
+In this mode the digest, key, salt and info values must be set before a key is
+derived otherwise an error will occur.
+
+=item EVP_KDF_HKDF_MODE_EXTRACT_ONLY
+
+In this mode calling L<EVP_KDF_derive(3)> will just perform the extract
+operation. The value returned will be the intermediate fixed-length pseudorandom
+key K.  The C<keylen> parameter must match the size of K, which can be looked
+up by calling EVP_KDF_size() after setting the mode and digest.
+
+The digest, key and salt values must be set before a key is derived otherwise
+an error will occur.
+
+=item EVP_KDF_HKDF_MODE_EXPAND_ONLY
+
+In this mode calling L<EVP_KDF_derive(3)> will just perform the expand
+operation. The input key should be set to the intermediate fixed-length
+pseudorandom key K returned from a previous extract operation.
+
+The digest, key and info values must be set before a key is derived otherwise
+an error will occur.
+
+=back
+
+EVP_KDF_ctrl_str() type string: "mode"
+
+The value string is expected to be one of: "EXTRACT_AND_EXPAND", "EXTRACT_ONLY"
+or "EXPAND_ONLY".
+
+=back
+
+=head1 NOTES
+
+A context for HKDF can be obtained by calling:
+
+ EVP_KDF_CTX *kctx = EVP_KDF_CTX_new_id(EVP_KDF_HKDF);
+
+The output length of an HKDF expand operation is specified via the C<keylen>
+parameter to the L<EVP_KDF_derive(3)> function.  When using
+EVP_KDF_HKDF_MODE_EXTRACT_ONLY the C<keylen> parameter must equal the size of
+the intermediate fixed-length pseudorandom key otherwise an error will occur.
+For that mode, the fixed output size can be looked up by calling EVP_KDF_size()
+after setting the mode and digest on the C<EVP_KDF_CTX>.
+
+=head1 EXAMPLE
+
+This example derives 10 bytes using SHA-256 with the secret key "secret",
+salt value "salt" and info value "label":

+ EVP_KDF_CTX *kctx;
+ unsigned char out[10];
+

+B<iter> is the iteration count and its value should be greater than or equal to

+
+A typical application of this algorithm is to derive keying material for an
+encryption algorithm from a password in the B<pass>, a salt in B<salt>,
+and an iteration count.
+
+Increasing the B<iter> parameter slows down the algorithm which makes it
+harder for an attacker to perform a brute force attack using a large number

+
+EVP_KDF_SCRYPT - The scrypt EVP_KDF implementation
+
+=head1 DESCRIPTION
+
+Support for computing the B<scrypt> password-based KDF through the B<EVP_KDF>
+API.
+
+The EVP_KDF_SCRYPT algorithm implements the scrypt password-based key
+derivation function, as described in RFC 7914.  It is memory-hard in the sense
+that it deliberately requires a significant amount of RAM for efficient
+computation. The intention of this is to render brute forcing of passwords on
+systems that lack large amounts of main memory (such as GPUs or ASICs)
+computationally infeasible.
+
+scrypt provides three work factors that can be customized: N, r and p. N, which
+has to be a positive power of two, is the general work factor and scales CPU
+time in an approximately linear fashion. r is the block size of the internally
+used hash function and p is the parallelization factor. Both r and p need to be
+greater than zero. The amount of RAM that scrypt requires for its computation
+is roughly (128 * N * r * p) bytes.
+
+In the original paper of Colin Percival ("Stronger Key Derivation via
+Sequential Memory-Hard Functions", 2009), the suggested values that give a
+computation time of less than 5 seconds on a 2.5 GHz Intel Core 2 Duo are N =
+2^20 = 1048576, r = 8, p = 1. Consequently, the required amount of memory for
+this computation is roughly 1 GiB. On a more recent CPU (Intel i7-5930K at 3.5
+GHz), this computation takes about 3 seconds. When N, r or p are not specified,
+they default to 1048576, 8, and 1, respectively. The maximum amount of RAM that
+may be used by scrypt defaults to 1025 MiB.

+=head1 NAME
+
+EVP_KDF_TLS1_PRF - The TLS1 PRF EVP_KDF implementation
+
+=head1 DESCRIPTION
+
+Support for computing the B<TLS1> PRF through the B<EVP_KDF> API.
+
+The EVP_KDF_TLS1_PRF algorithm implements the PRF used by TLS versions up to
+and including TLS 1.2.
+
+=head2 Numeric identity
+
+B<EVP_KDF_TLS1_PRF> is the numeric identity for this implementation; it
+can be used with the EVP_KDF_CTX_new_id() function.
+
+=head2 Supported controls
+
+The supported controls are:
+
+=over 4
+
+=item B<EVP_KDF_CTRL_SET_MD>
+
+This control works as described in L<EVP_KDF_CTX(3)/CONTROLS>.
+
+The C<EVP_KDF_CTRL_SET_MD> control is used to set the message digest associated
+with the TLS PRF.  EVP_md5_sha1() is treated as a special case which uses the
+PRF algorithm using both B<MD5> and B<SHA1> as used in TLS 1.0 and 1.1.
+
+=item B<EVP_KDF_CTRL_SET_TLS_SECRET>
+
+This control expects two arguments: C<unsigned char *sec>, C<size_t seclen>
+
+Sets the secret value of the TLS PRF to B<seclen> bytes of the buffer B<sec>.
+Any existing secret value is replaced.
+
+EVP_KDF_ctrl_str() takes two type strings for this control:
+
+=over 4
+
+=item "secret"
+
+The value string is used as is.
+
+=item "hexsecret"
+
+The value string is expected to be a hexadecimal number, which will be
+decoded before being passed on as the control value.
+
+=back
+
+=item B<EVP_KDF_CTRL_RESET_TLS_SEED>
+
+This control does not expect any arguments.
+
+Resets the context seed buffer to zero length.
+
+=item B<EVP_KDF_CTRL_ADD_TLS_SEED>
+
+This control expects two arguments: C<unsigned char *seed>, C<size_t seedlen>
+
+Sets the seed to B<seedlen> bytes of B<seed>.  If a seed is already set it is
+appended to the existing value.
+
+The total length of the context seed buffer cannot exceed 1024 bytes;
+this should be more than enough for any normal use of the TLS PRF.
+
+EVP_KDF_ctrl_str() takes two type strings for this control:
+
+=over 4
+
+=item "seed"
+
+The value string is used as is.
+
+=item "hexseed"
+
+The value string is expected to be a hexadecimal number, which will be
+decoded before being passed on as the control value.
+
+=back
+
+=back
+
+=head1 NOTES
+
+A context for the TLS PRF can be obtained by calling:
+
+ EVP_KDF_CTX *kctx = EVP_KDF_CTX_new_id(EVP_KDF_TLS1_PRF, NULL);
+
+The digest, secret value and seed must be set before a key is derived otherwise
+an error will occur.
+
+The output length of the PRF is specified by the C<keylen> parameter to the
+EVP_KDF_derive() function.
+
+=head1 EXAMPLE
+
+This example derives 10 bytes using SHA-256 with the secret key "secret"
+and seed value "seed":
+
+ EVP_KDF_CTX *kctx;
+ unsigned char out[10];
+
+ kctx = EVP_KDF_CTX_new_id(EVP_KDF_TLS1_PRF);
+ 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_TLS_SECRET,
+                  "secret", (size_t)6) <= 0) {
+     error("EVP_KDF_CTRL_SET_TLS_SECRET");
+ }
+ if (EVP_KDF_ctrl(kctx, EVP_KDF_CTRL_ADD_TLS_SEED, "seed", (size_t)4) <= 0) {
+     error("EVP_KDF_CTRL_ADD_TLS_SEED");
+ }
+ if (EVP_KDF_derive(kctx, out, sizeof(out)) <= 0) {
+     error("EVP_KDF_derive");
+ }
+ EVP_KDF_CTX_free(kctx);
