Member Function Documentation

fromDER() [1/2]

static std::unique_ptr<X509Certificate> pcpp::X509Certificate::fromDER ( const std::string &  derData )

static

Creates an X509Certificate from a hex string containing DER-encoded data

Parameters

[in]

derData

Hex string containing DER-encoded certificate data

Returns

A unique pointer to the created X509Certificate

Exceptions

An	exception if the data is not a valid ASN.1 record

fromDER() [2/2]

static std::unique_ptr<X509Certificate> pcpp::X509Certificate::fromDER ( uint8_t *  derData, size_t  derDataLen, bool  ownDerData = false  )

static

Creates an X509Certificate from DER-encoded data

Parameters

[in]	derData	Pointer to the DER-encoded certificate data
[in]	derDataLen	Length of the DER-encoded data
[in]	ownDerData	If true, the certificate will take ownership of the data and free it when the certificate class is destructed

Returns

A unique pointer to the created X509Certificate

Exceptions

An	exception if the data is not a valid ASN.1 record
