LDicomNet::GetEncryptionAlgorithmTLS

#include "ltdic.h"

L_UINT32 LDicomNet::GetEncryptionAlgorithmTLS(cipher)

/* the ciphersuite */

Returns the encryption mode (DES, 3DES, etc) for the cipher. This function is available in the PACS Imaging toolkits.

Parameter	Description
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_NONE	[0x00] No encryption. Returned if no secure connection is established.
L_CRYPT_DES	[0x01] DES encryption.
L_CRYPT_3DES	[0x02] 3DES encryption.
L_CRYPT_RC4	[0x03] RC4 encryption.
L_CRYPT_RC2	[0x04] RC2 encryption.
L_CRYPT_IDEA	[0x05] International Data Encryption Algorithm.
L_CRYPT_FORTEZZA	[0x06] Fortezza encryption.

Comments

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