L_DicomGetMutualAuthKeyLengthTLS

Summary

Returns the effective length (in bits) of the mutual authentication key associated with the specified ciphersuite. This function is available in Medical Suitetoolkits.

Syntax

#include "ltdic.h"

L_LTDIC_API L_UINT32 L_DicomGetMutualAuthKeyLengthTLS(hNet, cipher)

Parameters

HDICOMNET hNet

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

L_CIPHERSUITE cipher

Value that represents the current ciphersuite for which to get the length of the mutual authentication key.

Returns

Returns the effective length of the mutual authentication key.

Comments

The usual sizes for a 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. In addition, the length of the mutual authentication key can be found only after a successful call to the L_DicomSetClientCertificateTLS or L_DicomSetServerCertificateTLS function.
