# ldns\_verify\_rrsig\_dsa(3)

verify signature data buffers

## NAME

ldns\_verify\_rrsig\_dsa, ldns\_verify\_rrsig\_rsasha1, ldns\_verify\_rrsig\_rsamd5 - verify signature data buffers

## 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);

ldns\_status ldns\_verify\_rrsig\_rsamd5(ldns\_buffer \*sig, ldns\_buffer \*rrset, ldns\_buffer \*key);

## DESCRIPTION

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

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

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

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