+.Sh DESCRIPTION
+.Fn X509_signature_dump
+writes the data bytes contained in the
+.Fa signature
+to
+.Fa bio
+in hexadecimal format with colons between bytes,
+18 bytes per output line, each line indented with
+.Fa indent
+space characters.
+.Pp
+.Fn X509_signature_print
+writes the name of the signature
+.Fa algorithm ,
+or, if no name for it is known, its object identifier (OID) to
+.Fa bio
+using
+.Xr i2a_ASN1_OBJECT 3 .
+After that, if a method object for the algorithm can be retrieved with
+.Xr EVP_PKEY_asn1_find 3
+and if that object defines a printing method, that printing method is
+used to print the
+.Fa signature .
+Otherwise, unless the
+.Fa signature
+is
+.Dv NULL ,
+it is printed using
+.Fn X509_signature_dump .
+.Sh RETURN VALUES
+These functions return 1 on success or 0 on failure.
+They fail and return as soon as any write operation fails.
