# [SYNOPSIS](#SYNOPSIS)

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

#include <ldns/ldns.h>

ldns\_status ldns\_verify\_rrsig\_dsa(ldns\_buffer \*sig, ldns\_buffer \*rrset, ldns\_buffer \*key);

ldns\_status ldns\_verify\_rrsig\_rsasha1(ldns\_buffer \*sig, ldns\_buffer \*rrset, ldns\_buffer \*key);

# [DESCRIPTION](#DESCRIPTION)

*ldns\_verify\_rrsig\_dsa*() verifies a buffer with signature data (DSA) for a buffer with rrset data with a buffer with key data.

**sig**: the signature data  
**rrset**: the rrset data, sorted and processed for verification  
**key**: the key data

*ldns\_verify\_rrsig\_rsasha1*() verifies a buffer with signature data (RSASHA1) for a buffer with rrset data with a buffer with key data.

**sig**: the signature data  
**rrset**: the rrset data, sorted and processed for verification  
**key**: the key data

*ldns\_verify\_rrsig\_rsamd5*() verifies a buffer with signature data (RSAMD5) for a buffer with rrset data with a buffer with key data.

**sig**: the signature data  
**rrset**: the rrset data, sorted and processed for verification  
**key**: the key data
