GetFileEncryption Method

Retrieves the encryption mode of a file or alternate stream.

Syntax

public int getFileEncryption(String fileName);

Remarks

This method retrieves the encryption mode of the file or alternate stream specified by FileName.

The value passed for FileName must be a vault-local absolute path.

The returned encryption mode will be one of the following values:

CBFSSTORAGE_EM_NONE0x0Don't use encryption.

CBFSSTORAGE_EM_DEFAULT0x1Use default encryption (CBFSSTORAGE_EM_XTS_AES256_PBKDF2_HMAC_SHA256).

CBFSSTORAGE_EM_XTS_AES256_PBKDF2_HMAC_SHA2560x2Use AES256 encryption with PBKDF2 key derivation based on a HMAC_SHA256 key hash.

CBFSSTORAGE_EM_CUSTOM256_PBKDF2_HMAC_SHA2560x3Use event-based custom 256-bit encryption with PBKDF2 key derivation based on a HMAC_SHA256 key hash.

256-bit (32-byte) block size.

CBFSSTORAGE_EM_CUSTOM512_PBKDF2_HMAC_SHA2560x4Use event-based custom 512-bit encryption with PBKDF2 key derivation based on a HMAC_SHA256 key hash.

512-bit (64-byte) block size.

CBFSSTORAGE_EM_CUSTOM1024_PBKDF2_HMAC_SHA2560x5Use event-based custom 1024-bit encryption with PBKDF2 key derivation based on a HMAC_SHA256 key hash.

1024-bit (128-byte) block size.

CBFSSTORAGE_EM_CUSTOM256_CUSTOM_KEY_DERIVE0x23Use event-based custom 256-bit encryption with custom key derivation.

256-bit (32-byte) block size.

CBFSSTORAGE_EM_CUSTOM512_CUSTOM_KEY_DERIVE0x24Use event-based custom 512-bit encryption with custom key derivation.

512-bit (64-byte) block size.

CBFSSTORAGE_EM_CUSTOM1024_CUSTOM_KEY_DERIVE0x25Use event-based custom 1024-bit encryption with custom key derivation.

1024-bit (128-byte) block size.

CBFSSTORAGE_EM_CUSTOM256_DIRECT_KEY0x43Use event-based custom 256-bit encryption with no key derivation.

256-bit (32-byte) block size. Useful for cases where the password is an identifier for an external key and should not be used for key derivation.

CBFSSTORAGE_EM_CUSTOM512_DIRECT_KEY0x44Use event-based custom 512-bit encryption with no key derivation.

512-bit (64-byte) block size. Useful for cases where the password is an identifier for an external key and should not be used for key derivation.

CBFSSTORAGE_EM_CUSTOM1024_DIRECT_KEY0x45Use event-based custom 1024-bit encryption with no key derivation.

1024-bit (128-byte) block size. Useful for cases where the password is an identifier for an external key and should not be used for key derivation.

CBFSSTORAGE_EM_UNKNOWN0xFFUnidentified or unknown encryption.

Applications that use custom encryption must implement at least the DataDecrypt and DataEncrypt events; and certain custom encryption modes may also require that the HashCalculate or KeyDerive event be implemented as well. Please refer to the Encryption topic for more information.

Note: This method can only be called when Active is true.
