L_DicomSetServerCertificateTLS

#include "ltdic.h"

L_LTDIC_API L_UINT32 L_DicomSetServerCertificateTLS(hNet, pszPathToCertificateFile, nCertType, pszPathToKeyFile)

HDICOMNET hNet;

/* handle to an existing DICOM Network */

L_TCHAR *pszPathToCertificateFile;

/* path to the file that contains the certificate */

L_UINT32 nCertType;

/* certificate type */

L_TCHAR *pszPathToKeyFile;

/* path to the file containing the private key */

Sets a certificate for the server. This function is available in the Medical Suite toolkits.

Parameter

Description

hNet

Handle to an existing DICOM Network. This is the handle returned from the L_DicomCreateNet function.

pszPathToCertificate

Character string that contains the path to the file that contains the certificate.

nCertType

Flag that indicates whether the certificate is binary or text. Possible values are:

 

Value

Meaning

 

L_TLS_FILETYPE_PEM

Text certificate

 

L_TLS_FILETYPE_ASN1

Binary certificate

pszPathToKeyFile

Character string that contains the path to the file containing the private key. This parameter is used if the private key is available in raw mode.

Returns

DICOM_SUCCESS

Success.

<>DICOM_SUCCESS

An error occurred. Refer to the Return Codes.

Comments

The usual sizes for an RSA key is 512 and 1024 bits. There is a limitation for import in Europe a RSA key must be at least 768 bits long. There are no known export restrictions.

The server is authenticated always. A server may be authenticated with a chain of certificates, all in the same file.
