# [SYNOPSIS](#SYNOPSIS)

#include <stdint.h>  
#include <stdbool.h>

#include <ldns/ldns.h>

ldns\_rdf* ldns\_sign\_public\_dsa(ldns\_buffer \*to\_sign, DSA \*key);

ldns\_rdf* ldns\_sign\_public\_rsamd5(ldns\_buffer \*to\_sign, RSA \*key);

ldns\_rdf* ldns\_sign\_public\_rsasha1(ldns\_buffer \*to\_sign, RSA \*key);

# [DESCRIPTION](#DESCRIPTION)

*ldns\_sign\_public\_dsa*() Sign a buffer with the DSA key (hash with SHA1)

**to\_sign**: The ldns\_buffer containing raw data that is to be signed  
**key**: The DSA key structure to sign with  
Returns a ldns\_rdf for the RRSIG ldns\_rr

*ldns\_sign\_public\_rsamd5*() Sign a buffer with the RSA key (hash with MD5)  
**to\_sign**: buffer with the data  
**key**: the key to use  
Returns a ldns\_rdf with the signed data

*ldns\_sign\_public\_rsasha1*() Sign a buffer with the RSA key (hash with SHA1)  
**to\_sign**: buffer with the data  
**key**: the key to use  
Returns a ldns\_rdf with the signed data
