+=head1 DESCRIPTION
+
+X509_get0_signature() sets B<*psig> to the signature of B<x> and B<*palg>
+to the signature algorithm of B<x>. The values returned are internal
+pointers which B<MUST NOT> be freed up after the call.
+
+X509_get0_tbs_sigalg() returns the signature algorithm in the signed
+portion of B<x>.
+
+X509_get_signature_nid() returns the NID corresponding to the signature
+algorithm of B<x>.
+
+X509_REQ_get0_signature(), X509_REQ_get_signature_nid()
+X509_CRL_get0_signature() and X509_CRL_get_signature_nid() perform the
+same function for certificate requests and CRLs.
+
+=head1 NOTES
+
+These functions provide lower level access to signatures in certificates
+where an application wishes to analyse or generate a signature in a form
+where X509_sign() et al is not appropriate (for example a non standard
+or unsupported format).
+
+=head1 RETURN VALUES
+
+X509_get_signature_nid(), X509_REQ_get_signature_nid() and
+X509_CRL_get_signature_nid() return a NID.
+
+X509_get0_signature(), X509_REQ_get0_signature() and
+X509_CRL_get0_signature() do not return values.

+=head1 HISTORY
+
+X509_get0_signature() and X509_get_signature_nid() were first added to
+OpenSSL 1.0.2.
+
+X509_REQ_get0_signature(), X509_REQ_get_signature_nid(),
+X509_CRL_get0_signature() and X509_CRL_get_signature_nid() were first added
+to OpenSSL 1.1.0.
