The DICOMOPENSSLVERSION structure contains information about the availability and version of the OpenSSL libraries.

Member Description
uStructSize Size of this structure in bytes, for versioning. Use the sizeof() operator to calculate this value.
uFlags Reserved for future use. Must be 0.
szRequiredVersion A character string to be updated with the version of the OpenSSL libraries that is required to enable secure DICOM communication support, including:
DICOM Digital Signatures
DICOM Communication using the TLS Security Profile
szInstalledVersion A character string to be updated with the currently installed version of OpenSSL libraries, if the value of bIsAvailable is TRUE.
bIsAvailable Flag that indicates the availability of OpenSSL libraries. Possible values are:
Value Meaning
TRUE _OpenSSL_ libraries are present and the version of the OpenSSL libraries is the value of szRequiredVersion.
FALSE _OpenSSL_ libraries are present.
szDownloadMessage A character string to be updated with instructions for downloading OpenSSL binaries and source code, if the value of bIsAvailable is FALSE.



LEADTOOLS uses OpenSSL for secure DICOM communication. LEAD does not ship the required OpenSSL binaries. You must obtain these DLLs yourself, before you can use secure DICOM communication features.
