L_DicomGetMutualAuthKeyLengthTLS
#include "ltdic.h"
L_UINT32 L_DicomGetMutualAuthKeyLengthTLS(hNet, cipher)
HDICOMNET hNet; |
/* handle to an existing DICOM Network */ |
L_CIPHERSUITE cipher; |
/* ciphersuite */ |
Returns the effective length (in bits) of the mutual authentication key associated with the specified ciphersuite. This function is available in Medical Suite toolkits.
Parameter |
Description |
hNet |
Handle to an existing DICOM Network. This is the handle returned from the L_DicomCreateNet function. |
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.
