Informazioni su Let's Encrypt

webatla monitora 52.655 siti web attivi che utilizzano Let's Encrypt, ovvero 0.0% di tutti i siti che indicizziamo. Scarichi l’elenco completo dei siti web che utilizzano Let's Encrypt come esportazione JSONL giornaliera. Ogni record include il dominio, oltre a DNS, WHOIS, indirizzo IP, paese di hosting e ranking globale.

Let’s Encrypt è un’autorità di certificazione (CA) gratuita, automatizzata e aperta che fornisce certificati TLS/SSL ai siti web per abilitare l’HTTPS. Lanciata nel 2016 dall’Internet Security Research Group (ISRG) e sostenuta da grandi sponsor, tra cui Mozilla, l’Electronic Frontier Foundation e Cisco, ha abbassato drasticamente la barriera all’adozione del traffico web crittografato.

Let’s Encrypt utilizza il protocollo ACME per automatizzare l’emissione e il rinnovo dei certificati, consentendo agli amministratori di server e ai fornitori di hosting di ottenere e rinnovare i certificati senza intervento manuale. Ha emesso certificati per centinaia di milioni di siti web, diventando la più grande autorità di certificazione al mondo per numero di certificati. Il servizio è fornito interamente gratuitamente come beneficio pubblico.

When using the Public Interest Registry RDAP service, please consider the following: the RDAP service is not a replacement for standard EPP commands to the SRS service. RDAP is not considered authoritative for registered domain objects. The RDAP service may be scheduled for downtime during production or OT&E maintenance periods. Queries to the RDAP services are throttled. If too many queries are received from a single IP address within a specified time, the service will begin to reject further queries for a period of time to prevent disruption of RDAP service access. Abuse of the RDAP system through data mining is mitigated by detecting and limiting bulk query access from single sources. Where applicable, the presence of a [Non-Public Data] tag indicates that such data is not made publicly available due to applicable data privacy laws or requirements. Should you wish to contact the registrant, please refer to the RDAP records available through the registrar URL listed above. Access to non-public data may be provided, upon request, where it can be reasonably confirmed that the requester holds a specific legitimate interest and a proper legal basis for accessing the withheld data. Access to this data can be requested by submitting a request to WHOISrequest@pir.org. Public Interest Registry Inc. reserves the right to modify these terms at any time. By submitting this query, you agree to abide by this policy."]},{"links":[{"rel":"glossary","href":"https://icann.org/epp","type":"application/rdap+json","value":"https://rdap.publicinterestregistry.org/rdap/domain/ijea.org"}],"title":"Status Codes","description":["For more information on domain status codes, please visit https://icann.org/epp"]},{"links":[{"rel":"help","href":"https://icann.org/wicf","type":"application/rdap+json","value":"https://rdap.publicinterestregistry.org/rdap/domain/ijea.org"}],"title":"RDDS Inaccuracy Complaint Form","description":["URL of the ICANN RDDS Inaccuracy Complaint Form: https://icann.org/wicf"]}],"entities":[{"links":[{"rel":"self","href":"https://rdap.publicinterestregistry.org/rdap/entity/69","type":"application/rdap+json","value":"https://rdap.publicinterestregistry.org/rdap/entity/69"},{"rel":"about","href":"https://opensrs.rdap.tucows.com/","type":"application/rdap+json","value":"https://opensrs.rdap.tucows.com/"}],"roles":["registrar"],"handle":"69","entities":[{"roles":["abuse"],"vcardArray":["vcard",[["version",{},"text","4.0"],["fn",{},"text",""],["tel",{"type":"voice"},"uri","tel:+1.4165350123"],["email",{},"text","domainabuse@tucows.com"]]],"objectClassName":"entity"}],"publicIds":[{"type":"IANA Registrar ID","identifier":"69"}],"vcardArray":["vcard",[["version",{},"text","4.0"],["fn",{},"text","Tucows Domains Inc."]]],"objectClassName":"entity"}],"redacted":[{"name":{"type":"Registry Domain ID"},"method":"removal","prePath":"$.handle","pathLang":"jsonpath"}],"secureDNS":{"maxSigLife":1,"delegationSigned":false},"nameservers":[{"handle":"fa056e34a15a49b8b79ad3d21a4e2096-LROR","status":["associated"],"ldhName":"ns1.gopher.arvixe.com","unicodeName":"ns1.gopher.arvixe.com","objectClassName":"nameserver"},{"handle":"c4d818fdd78b4e4c8be0a74032eccb36-LROR","status":["associated"],"ldhName":"ns2.gopher.arvixe.com","unicodeName":"ns2.gopher.arvixe.com","objectClassName":"nameserver"}],"unicodeName":"ijea.org","objectClassName":"domain","rdapConformance":["rdap_level_0","icann_rdap_response_profile_1","icann_rdap_technical_implementation_guide_1","redacted"]}}Domain is active
