ANNENCRYPTOPTIONS

Summary

The ANNENCRYPTOPTIONS structure provides options on an annotation encrypt object. This encrypt object may be in the encryptor state or the decryptor state.

Syntax

typedef struct tagANNENCRYPTOPTIONS 
{ 
   L_UINT uStructSize; 
   L_UINT uFlags; 
   L_BOOL bEncryptor; 
   L_UINT32 uKey; 
   L_BOOL bNeverEncrypted; 
   pBITMAPHANDLE pEncryptBitmap; 
   L_BOOL bSaveEncryptorKey; 
   L_BOOL bSaveDecryptorKey; 
   L_BOOL bClearEncryptorKey; 
   L_BOOL bClearDecryptorKey; 
   L_UINT uBitmapStructSize; 
   L_INT32 nReserved; 
} ANNENCRYPTOPTIONS, *pANNENCRYPTOPTIONS;

Members

uStructSize

Size of this structure. Use sizeof(ANNENCRYPTOPTIONS)

uFlags

Flags that identify which files to set or get. Possible values are one or more of the following constants "or"ed together:

Value	Meaning
ANNENCRYPT_TYPE	[0x001] Get or set the bEncryptor field.
ANNENCRYPT_KEY	[0x002] Get or set the uKey field.
ANNENCRYPT_RESERVED1	[0x004] Reserved for future use.
ANNENCRYPT_NEVER_ENCRYPTED	[0x008] Get or set the bNeverEncrypted field.
ANNENCRYPT_ENCRYPT_BITMAP	[0x010] Get or set the pEncryptBitmap field.
ANNENCRYPT_SAVE_ENCRYPTOR_KEY	[0x020] Get or set the bSaveEncryptorKey field.
ANNENCRYPT_SAVE_DECRYPTOR_KEY	[0x040] Get or set the bSaveDecryptorKey field.
ANNENCRYPT_CLEAR_ENCRYPTOR_KEY	[0x080] Get or set the bClearEncryptorKey field.
ANNENCRYPT_CLEAR_DECRYPTOR_KEY	[0x100] Get or set the bClearDecryptorKey field.
ANNENCRYPT_VIEWPERSPECTIVE	[0x200] Reserved for internal use.
ANNENCRYPT_ALL	[0x3FF] Get or set all fields.

bEncryptor

Flag that indicates whether the object is an encryptor or decryptor. Possible values are:

Value	Meaning
TRUE	The object is an encryptor.
FALSE	The object is a decryptor.

uKey

Key that is used for the encryption/decryption. This is an unsigned integer with a minimum value of 0 and a maximum value of 4294967295 (0xffffffff). When used in automation using the Encrypt dialog (right-clicking an encryptor), the maximum value is 999999999. When decrypting, use the same key that was used when the encryptor was applied.

bNeverEncrypted

Flag that indicates whether you can change the key and location of the decryptor. This field is only relevant for decryptors (bEncryptor is FALSE). Possible values are:

Value	Meaning
TRUE	The decryptor has never been encrypted. This means that in automation, the key and location of the decryptor can be changed.
FALSE	The decryptor was originally an encryptor that was applied. You cannot change the key or location of this kind of decryptor.

pEncryptBitmap

Pointer to the bitmap that is being encrypted or decrypted.

bSaveEncryptorKey

Flag that indicates if encryptor keys are saved. Possible values are:

Value	Meaning
TRUE	Encryptor keys are saved with L_AnnSave, L_AnnSaveOffset, L_AnnSaveMemory, L_AnnSaveTag.
FALSE	Encryptor keys are saved with a value of 0 with L_AnnSave, L_AnnSaveOffset, L_AnnSaveMemory, L_AnnSaveTag.

bSaveDecryptorKey

Flag that indicates if decryptor keys are saved. Possible values are:

Value	Meaning
TRUE	Decryptor keys are saved with L_AnnSave, L_AnnSaveOffset, L_AnnSaveMemory, L_AnnSaveTag.
FALSE	Decryptor keys are saved with a value of 0 with L_AnnSave, L_AnnSaveOffset, L_AnnSaveMemory, L_AnnSaveTag.

bClearEncryptorKey

Flag that indicates what happens to encrypt keys after calling L_AnnEncryptApply. Possible values are:

Value	Meaning
TRUE	All encrypt objects whose state has become ‘encryptor’ have the key set to 0.
FALSE	All encrypt objects whose state has become ‘encryptor’ have the key unchanged.

bClearDecryptorKey

Flag that indicates what happens to encrypt keys after calling L_AnnEncryptApply. Possible values are:

Value	Meaning
TRUE	All encrypt objects whose state has become ‘decryptor’ have the key set to 0.
FALSE	All encrypt objects whose state has become ‘decryptor’ have the key unchanged.
