+.SH "NAME"
+EVP_KDF\-SS \- The Single Step / One Step EVP_KDF implementation
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The \s-1EVP_KDF\-SS\s0 algorithm implements the Single Step key derivation function (\s-1SSKDF\s0).
+\&\s-1SSKDF\s0 derives a key using input such as a shared secret key (that was generated
+during the execution of a key establishment scheme) and fixedinfo.
+\&\s-1SSKDF\s0 is also informally referred to as 'Concat \s-1KDF\s0'.
+.SS "Auxiliary function"
+.IX Subsection "Auxiliary function"
+The implementation uses a selectable auxiliary function H, which can be one of:
+.IP "\fBH(x) = hash(x, digest=md)\fR" 4
+.IX Item "H(x) = hash(x, digest=md)"
+.PD 0
+.IP "\fBH(x) = HMAC_hash(x, key=salt, digest=md)\fR" 4
+.IX Item "H(x) = HMAC_hash(x, key=salt, digest=md)"
+.ie n .IP "\fBH(x) = KMACxxx(x, key=salt, custom=""\s-1KDF"",\s0 outlen=mac_size)\fR" 4
+.el .IP "\fBH(x) = KMACxxx(x, key=salt, custom=``\s-1KDF'',\s0 outlen=mac_size)\fR" 4
+.IX Item "H(x) = KMACxxx(x, key=salt, custom=KDF, outlen=mac_size)"
+.PD
+.PP
+Both the \s-1HMAC\s0 and \s-1KMAC\s0 implementations set the key using the 'salt' value.
+The hash and \s-1HMAC\s0 also require the digest to be set.
+.SS "Identity"
+.IX Subsection "Identity"
+\&\*(L"\s-1SSKDF\*(R"\s0 is the name for this implementation; it
+can be used with the \fBEVP_KDF_fetch()\fR function.
