V\u00fdbor IETF (Internet Engineering Task Force), ktor\u00fd sa zaober\u00e1 rozvojom protokolov a architekt\u00fary internetu, zverejnil RFC 8996, ktor\u00fd ofici\u00e1lne zara\u010fuje protokoly TLS 1.0 a 1.1 medzi zastaran\u00e9 technol\u00f3gie. <\/p>\n
\u0160pecifik\u00e1cia TLS 1.0 bola publikovan\u00e1 v janu\u00e1ri 1999.
