LDicomNet::GetEncryptKeyLengthTLS

#include "ltdic.h"

L_UINT32 LDicomNet::GetEncryptKeyLengthTLS(cipher)

ciphersuite

Returns the effective length (in bits) of the encryption key associated with the specified ciphersuite (56 for DES etc). This function is available in the PACS Imaging toolkits.

Parameter	Description
cipher	Value that indicates the ciphersuite for which to get the length of the encryption key.

Returns

Returns the effective length of the encryption key associated with the specified ciphersuite.

Comments

There are differences between the size of the key and the effective length. The security of a key is given by the effective length, not by the size (a DES key has 8 bytes, just like a DES40 key, but the first has 56 bits effective, and the second only 40.)
