L_DicomGetEncryptionAlgorithmTLS

L_LTDIC_API L_UINT32 L_DicomGetEncryptionAlgorithmTLS (hNet, cipher)

HDICOMNET hNet;	/* handle to an existing DICOM Network */
L_CIPHERSUITE cipher;	/* the ciphersuite */

Returns the encryption mode (DES, 3DES, etc) for the cipher. 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.
cipher	Value that indicates the ciphersuite for which to get the encryption mode or algorithm.

Returns

A value that indicates the encryption mode or algorithm. Possible values are:

Value	Meaning
L_CRYPT_DES	[0x01] DES encryption.
L_CRYPT_3DES	[0x02] 3DES encryption.

Comments

There are several different cipher suites. Some of these differ only in encryption mode or algorithm.
