+# AESContext
+
+**Inherits:** [RefCounted](class_refcounted.md) **<** [Object](class_object.md)
+
+Provides access to AES encryption/decryption of raw data.
+
+<!-- classref-introduction-group -->
+
+## Description
+
+This class holds the context information required for encryption and decryption operations with AES (Advanced Encryption Standard). Both AES-ECB and AES-CBC modes are supported.
+
+

+
+```gdscript

+
+    var aes = AESContext.new()
+
+    func _ready():
+        var key = "My secret key!!!" # Key must be either 16 or 32 bytes.
+        var data = "My secret text!!" # Data size must be multiple of 16 bytes, apply padding if needed.
+        # Encrypt ECB
+        aes.start(AESContext.MODE_ECB_ENCRYPT, key.to_utf8_buffer())

+
+`void` **finish**\ (\ ) [🔗](#class_AESContext_method_finish)
+
+Close this AES context so it can be started again. See [start()](class_aescontext.md#class_AESContext_method_start).
+
+<hr class="classref-item-separator">
+
+<a id="class_AESContext_method_get_iv_state"></a>

+
+[PackedByteArray](class_packedbytearray.md) **get_iv_state**\ (\ ) [🔗](#class_AESContext_method_get_iv_state)
+
+Get the current IV state for this context (IV gets updated when calling [update()](class_aescontext.md#class_AESContext_method_update)). You normally don't need this function.
+
+\ **Note:** This function only makes sense when the context is started with [MODE_CBC_ENCRYPT](class_aescontext.md#class_AESContext_constant_MODE_CBC_ENCRYPT) or [MODE_CBC_DECRYPT](class_aescontext.md#class_AESContext_constant_MODE_CBC_DECRYPT).

+
+Start the AES context in the given `mode`. A `key` of either 16 or 32 bytes must always be provided, while an `iv` (initialization vector) of exactly 16 bytes, is only needed when `mode` is either [MODE_CBC_ENCRYPT](class_aescontext.md#class_AESContext_constant_MODE_CBC_ENCRYPT) or [MODE_CBC_DECRYPT](class_aescontext.md#class_AESContext_constant_MODE_CBC_DECRYPT).

+
+[PackedByteArray](class_packedbytearray.md) **update**\ (\ src\: [PackedByteArray](class_packedbytearray.md)\ ) [🔗](#class_AESContext_method_update)
+
+Run the desired operation for this AES context. Will return a [PackedByteArray](class_packedbytearray.md) containing the result of encrypting (or decrypting) the given `src`. See [start()](class_aescontext.md#class_AESContext_method_start) for mode of operation.
+
+\ **Note:** The size of `src` must be a multiple of 16. Apply some padding if needed.
