Detailed Description

Represents TLS Supported Versions extension. Inherits from SSLExtension and adds parsing of the list of supported versions mentioned in the extension data

Member Function Documentation

getSupportedVersions()

std::vector<SSLVersion> pcpp::SSLSupportedVersionsExtension::getSupportedVersions

(

)

const

Returns

The list of supported versions mentioned in the extension data

SSLExtension() [1/2]

pcpp::SSLExtension::SSLExtension

explicit

C'tor for this class

Parameters

[in]

data

The raw data for the extension

Deprecated:

This constructor is deprecated because it uses an unbound memory span. Use the constructor with bounded span.

SSLExtension() [2/2]

pcpp::SSLExtension::SSLExtension

Constructs an SSLExtension that interprets the provided data as the raw bytes of the extension.

The memory span defined by data and dataLen can be larger than the actual extension data. If so, only the bytes corresponding to the extension header (type and length fields) + [length] bytes of extension data will be parsed. The rest of the span will be ignored.

The above behaviour allows variable length extensions to be parsed, as SSL extensions are laid out sequentially in memory on a payload.

Parameters

[in]	data	The raw data for the extension.
[in]	dataLen	The length of the data in bytes.

Exceptions

std::invalid_argument

if data is nullptr or if dataLen is smaller than the size of the extension header (type and length fields).
