LDicomNet::GetEncryptionAlgorithmTLS

#include "ltdic.h"

L_UINT32 LDicomNet::GetEncryptionAlgorithmTLS(cipher)

L_CIPHERSUITE 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.
