+.SH NAME
+EVP_KDF\-TLS1_PRF \- The TLS1 PRF EVP_KDF implementation
+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+Support for computing the \fBTLS1\fR PRF through the \fBEVP_KDF\fR API.
+.PP
+The EVP_KDF\-TLS1_PRF algorithm implements the PRF used by TLS versions up to
+and including TLS 1.2.
+.SS Identity
+.IX Subsection "Identity"
+"TLS1\-PRF" is the name for this implementation; it
+can be used with the \fBEVP_KDF_fetch()\fR function.
+.SS "Supported parameters"
+.IX Subsection "Supported parameters"
+The supported parameters are:
+.IP """properties"" (\fBOSSL_KDF_PARAM_PROPERTIES\fR) <UTF8 string>" 4
+.IX Item """properties"" (OSSL_KDF_PARAM_PROPERTIES) <UTF8 string>"
+.PD 0
+.IP """digest"" (\fBOSSL_KDF_PARAM_DIGEST\fR) <UTF8 string>" 4
+.IX Item """digest"" (OSSL_KDF_PARAM_DIGEST) <UTF8 string>"
+.PD
+These parameters work as described in "PARAMETERS" in \fBEVP_KDF\fR\|(3).
+.Sp
+The \fBOSSL_KDF_PARAM_DIGEST\fR parameter is used to set the message digest
+associated with the TLS PRF.
+\&\fBEVP_md5_sha1()\fR is treated as a special case which uses the
+PRF algorithm using both \fBMD5\fR and \fBSHA1\fR as used in TLS 1.0 and 1.1.
+.IP """secret"" (\fBOSSL_KDF_PARAM_SECRET\fR) <octet string>" 4
+.IX Item """secret"" (OSSL_KDF_PARAM_SECRET) <octet string>"
+This parameter sets the secret value of the TLS PRF.
+Any existing secret value is replaced.
+.IP """seed"" (\fBOSSL_KDF_PARAM_SEED\fR) <octet string>" 4
+.IX Item """seed"" (OSSL_KDF_PARAM_SEED) <octet string>"
+This parameter sets the context seed.
+The length of the context seed cannot exceed 1024 bytes;
+this should be more than enough for any normal use of the TLS PRF.
+.SH NOTES
+.IX Header "NOTES"
+A context for the TLS PRF can be obtained by calling:
+.PP
+.Vb 2
+\& EVP_KDF *kdf = EVP_KDF_fetch(NULL, "TLS1\-PRF", NULL);
+\& EVP_KDF_CTX *kctx = EVP_KDF_CTX_new(kdf);
+.Ve
+.PP
+The digest, secret value and seed must be set before a key is derived otherwise
+an error will occur.
+.PP
+The output length of the PRF is specified by the \fIkeylen\fR parameter to the
+\&\fBEVP_KDF_derive()\fR function.
+.SH EXAMPLES
+.IX Header "EXAMPLES"
+This example derives 10 bytes using SHA\-256 with the secret key "secret"
+and seed value "seed":
+.PP
+.Vb 4
+\& EVP_KDF *kdf;
+\& EVP_KDF_CTX *kctx;
+\& unsigned char out[10];
+\& OSSL_PARAM params[4], *p = params;
+\&
+\& kdf = EVP_KDF_fetch(NULL, "TLS1\-PRF", NULL);
+\& kctx = EVP_KDF_CTX_new(kdf);
+\& EVP_KDF_free(kdf);
+\&
+\& *p++ = OSSL_PARAM_construct_utf8_string(OSSL_KDF_PARAM_DIGEST,
+\&                                         SN_sha256, strlen(SN_sha256));
+\& *p++ = OSSL_PARAM_construct_octet_string(OSSL_KDF_PARAM_SECRET,
+\&                                          "secret", (size_t)6);
+\& *p++ = OSSL_PARAM_construct_octet_string(OSSL_KDF_PARAM_SEED,
+\&                                          "seed", (size_t)4);
+\& *p = OSSL_PARAM_construct_end();
+\& if (EVP_KDF_derive(kctx, out, sizeof(out), params) <= 0) {
+\&     error("EVP_KDF_derive");
