SecurityHandler Constructor (Int32, Int32)

public SecurityHandler(
	int key_len,
	int enc_code
)

Public Sub New ( 
	key_len As Integer,
	enc_code As Integer
)

public:
SecurityHandler(
	[InAttribute] int key_len, 
	[InAttribute] int enc_code
)

pdftron.SDF.SecurityHandler = function(key_len, enc_code);

Parameters

key_len

Type: SystemInt32
The bit length of the encryption key (40 or 128 bit).

enc_code

Type: SystemInt32
The encryption algorithm identifier. The number corresponds to the V entry in encryption dictionary. Currently allowed values are(see Table 3.18 in PDF Reference Manual v1.6 for more details):

1. Encryption using 40-bit RC4 algorithm.
2. Encryption using 128-bit RC4 algorithm. Available in PDF 1.4 and above.
3. This algorithm was deprecated by PDF standard and is not supported.
4. Encryption using Crypt filters and 128-bit AES(Advanced Encryption Standard) algorithm. Available in PDF 1.6 and above.
