L_DicomGetEncryptionAlgorithmTLS

L_LTDIC_API L_UINT32 L_DicomGetEncryptionAlgorithmTLS (hNet, cipher)

Returns the encryption mode (DES, 3DES, etc) for the 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 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.
