The ANNENCRYPTOPTIONS structure is used with the functions LAnnEncrypt::SetEncryptOptions and LAnnEncrypt::GetEncryptOptions to get or set options on an annotation encrypt object. This encrypt object may be in the encryptor state or the decryptor state.

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 LAnnContainer::Save, LAnnContainer::SaveOffset, LAnnContainer::SaveMemory, LAnnContainer::SaveTag.
FALSE	Encryptor keys are saved with a value of 0 with LAnnContainer::Save, LAnnContainer::SaveOffset, LAnnContainer::SaveMemory, LAnnContainer::SaveTag.

bSaveDecryptorKey

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

Value	Meaning
TRUE	Decryptor keys are saved with LAnnContainer::Save, LAnnContainer::SaveOffset, LAnnContainer::SaveMemory, LAnnContainer::SaveTag.
FALSE	Decryptor keys are saved with a value of 0 with LAnnContainer::Save, LAnnContainer::SaveOffset, LAnnContainer::SaveMemory, LAnnContainer::SaveTag.

bClearEncryptorKey

Flag that indicates what happens to encrypt keys after calling LAnnContainer::EncryptApply

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 LAnnContainer::EncryptApply.

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.
