+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+\&\fBX509_digest_sig()\fR calculates a digest of the given certificate \fIcert\fR
+using the same hash algorithm as in its signature, if the digest
+is an integral part of the certificate signature algorithm identifier.
+Otherwise, a fallback hash algorithm is determined as follows:
+SHA512 if the signature algorithm is ED25519,
+SHAKE256 if it is ED448, otherwise SHA256.
+The output parameters are assigned as follows.
+Unless \fImd_used\fR is NULL, the hash algorithm used is provided
+in \fI*md_used\fR and must be freed by the caller (if it is not NULL).
+Unless \fImd_is_fallback\fR is NULL,
+the \fI*md_is_fallback\fR is set to 1 if the hash algorithm used is a fallback,
+otherwise to 0.
+.PP
+\&\fBX509_pubkey_digest()\fR returns a digest of the DER representation of the public
+key in the specified X509 \fIdata\fR object.
+.PP
+All other functions described here return a digest of the DER representation
+of their entire \fIdata\fR objects.
+.PP
+The \fItype\fR parameter specifies the digest to
+be used, such as \fBEVP_sha1()\fR. The \fImd\fR is a pointer to the buffer where the
+digest will be copied and is assumed to be large enough; the constant
+\&\fBEVP_MAX_MD_SIZE\fR is suggested. The \fIlen\fR parameter, if not NULL, points
+to a place where the digest size will be stored.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBX509_digest_sig()\fR returns an ASN1_OCTET_STRING pointer on success, else NULL.
+.PP
+All other functions described here return 1 for success and 0 for failure.
