Writing Encrypted Arrays

To write to an encrypted array, you simply need to open it for writing using the encryption key you used to create it.

C

// ... create context ctx

// Open encrypted array for writing
const char key[] = "0123456789abcdeF0123456789abcdeF";
tiledb_config_t* config;
tiledb_config_alloc(&config, &error);
tiledb_config_set(config, "sm.encryption_type", "AES_256_GCM", &error);
tiledb_config_set(config, "sm.encryption_key", key, &error);

tiledb_array_t* array;
tiledb_array_alloc(ctx, "<array-uri>", &array);
tiledb_array_set_config(ctx, array, config);
tiledb_array_open(ctx, array, TILEDB_WRITE);

C++

// ... create context ctx

// Open encrypted array for writing
const char key[] = "0123456789abcdeF0123456789abcdeF";
Array array(ctx,
    "<array-uri>",
    TILEDB_WRITE,
    // Load all fragments available
    TemporalPolicy(0, std::numeric_limits<uint64_t>::max()),
    EncryptionAlgorithm(AESGCM, key));

Python

key = "0123456789abcdeF0123456789abcdeF"
tiledb.SparseArray.create(array_name, schema, key=key)
with tiledb.SparseArray(array_name, 'w', key=key) as A:
    # A[] = ...

with tiledb.open(array_name, key=key) as A:
    # read A[...]

R

ctx <- tiledb_ctx()
arrptr <- tiledb:::libtiledb_array_open_with_key(ctx@ptr, uridensewkey, 
                                                 "WRITE", encryption_key)

Java

// ... create context ctx

// Open encrypted array for writing
String key = "0123456789abcdeF0123456789abcdeF";
Array array(ctx, "<array-uri>", TILEDB_WRITE, TILEDB_AES_256_GCM, key..getBytes(StandardCharsets.UTF_8));

Go

// ... create context ctx

// The 256-bit encryption key, stored as a string for convenience.
var encryption_key = "0123456789abcdeF0123456789abcdeF"

// Open encrypted array for writing
array, _ := tiledb.NewArray(ctx, "<array-uri>")
array.CreateWithKey(schema, tiledb.TILEDB_AES_256_GCM, encryption_key)
