 ## Server
+
+### Set Data
+Just make a POST request to any path:
+
+**POST** `/hi`
+```
+Hello World!
+```
+
+#### TTL
+By default, the data is kept for 5 minutes. This TTL can be changed via the `ttl`-parameter.
+
+**POST** `/hi?ttl=1m30s`
+```
+Hello World!
+```
+
+#### Encryption
+By default, the data is not encrypted. 
+**It is not recommended to encrypt the data on server side. The data should always be encrypted on the client side.**
+
+However, if this is not possible, the `secret`-parameter can be used to specify a password with which the data should be encrypted.
+
+**POST** `/hi?secret=s3cr3tp455w0rd`
+```
+Hello World!
+```
+**Produces:**
+```
+gwttKS3Q2l0+YR+jQF/02u3fNVmMIcVOTNSGD5vWfrYTtH8adt8r
+```
+
+### Get Data
+**GET** `/hi`
+```
+Hello World!
+```
+
+#### Encryption
+If the data has been encrypted and should be decrypted on the server side (**which is not recommended**), the "password" can be passed via the `secret`-parameter.
+**GET** `/hi`
+```
+gwttKS3Q2l0+YR+jQF/02u3fNVmMIcVOTNSGD5vWfrYTtH8adt8r
+```
+
+**GET** `/hi?secret=s3cr3tp455w0rd`
