Deimhnithe SSL/TLS a Thuiscint
Is prótacail slándála iad SSL (Sraith Soicéad Slán) agus a chomharba TLS (Slándáil Sraith Iompair) a úsáidtear chun nasc criptithe a bhunú idir freastalaí gréasáin agus brabhsálaí.
Ceisteanna Coitianta SSL
Cad a tharlóidh má théann mo dheimhniú in éag?
Feicfidh úsáideoirí rabhaidh slándála ina mbrabhsálaí, agus d'fhéadfadh rochtain ar do shuíomh a bheith bactha. Mar thoradh air seo cailltear muinín agus titim i rangú rátálacha SEO.
Cén cineál deimhnithe SSL atá uaim?
Don chuid is mó de shuíomhanna gréasáin, is leor deimhniú caighdeánach DV (Bailíochtaithe Fearainn). Soláthraíonn deimhnithe OV nó EV muinín níos airde do shuíomhanna corparáideacha.
An SSL Certificate Checker is an online tool that verifies the validity, expiration date, issuer, and configuration of SSL/TLS certificates installed on web servers. It helps identify security vulnerabilities and certificate misconfigurations.

What happens when an SSL certificate expires?
Browsers display security warnings, your site may become inaccessible, SEO rankings drop, and customer trust is lost.
What is the difference between SSL and TLS?
TLS is the successor to SSL. Modern websites use TLS 1.2 or 1.3. TLS offers stronger security and better performance.
