+Dapr provides cross-platform and cross-language support for encryption and decryption support via the 
+cryptography building block. Besides the [language specific SDKs]({{<ref sdks>}}), a developer can invoke these capabilities using
+the HTTP API endpoints below.
+
+## Encrypt Payload
+
+This endpoint lets you encrypt a value provided as a byte array using a specified key and crypto component.
+
+### HTTP Request
+
+```
+PUT http://localhost:<daprPort>/v1.0/crypto/<crypto-store-name>/encrypt
+```
+
+#### URL Parameters
+ | Parameter         | Description                                                 |

+
+> Note, all URL parameters are case-sensitive.
+
+#### Headers
+Additional encryption parameters are configured by setting headers with the appropriate
+values. The following table details the required and optional headers to set with every
+encryption request.
