### _validate_rrsig(rrset, rrsig, keys, origin=None, now=None) | source code
Validate an RRset against a single signature rdata The owner name of the rrsig is assumed to be the same as the owner name of the rrset. Parameters: `rrset` (dns.rrset.RRset or (dns.name.Name, dns.rdataset.Rdataset) tuple) - The RRset to validate `rrsig` (dns.rrset.Rdata) - The signature rdata `keys` (a dictionary keyed by dns.name.Name with node or rdataset values) - The key dictionary. `origin` (dns.name.Name or None) - The origin to use for relative names `now` (int) - The time to use when validating the signatures. The default is the current time.

### _validate(rrset, rrsigset, keys, origin=None, now=None) | source code
Validate an RRset Parameters: `rrset` (dns.rrset.RRset or (dns.name.Name, dns.rdataset.Rdataset) tuple) - The RRset to validate `rrsigset` (dns.rrset.RRset or (dns.name.Name, dns.rdataset.Rdataset) tuple) - The signature RRset `keys` (a dictionary keyed by dns.name.Name with node or rdataset values) - The key dictionary. `origin` (dns.name.Name or None) - The origin to use for relative names `now` (int) - The time to use when validating the signatures. The default is the current time.

### validate(rrset, rrsigset, keys, origin=None, now=None) | source code
Validate an RRset Parameters: `rrset` (dns.rrset.RRset or (dns.name.Name, dns.rdataset.Rdataset) tuple) - The RRset to validate `rrsigset` (dns.rrset.RRset or (dns.name.Name, dns.rdataset.Rdataset) tuple) - The signature RRset `keys` (a dictionary keyed by dns.name.Name with node or rdataset values) - The key dictionary. `origin` (dns.name.Name or None) - The origin to use for relative names `now` (int) - The time to use when validating the signatures. The default is the current time.

### validate_rrsig(rrset, rrsig, keys, origin=None, now=None) | source code
Validate an RRset against a single signature rdata The owner name of the rrsig is assumed to be the same as the owner name of the rrset. Parameters: `rrset` (dns.rrset.RRset or (dns.name.Name, dns.rdataset.Rdataset) tuple) - The RRset to validate `rrsig` (dns.rrset.Rdata) - The signature rdata `keys` (a dictionary keyed by dns.name.Name with node or rdataset values) - The key dictionary. `origin` (dns.name.Name or None) - The origin to use for relative names `now` (int) - The time to use when validating the signatures. The default is the current time.
