+
+Java Vault Connector is a connector library for [Vault](https://www.vaultproject.io) by [Hashicorp](https://www.hashicorp.com) written in Java. The connector allows simple usage of Vault's secret store in own applications.
+
+## Features:
+
+* HTTP(S) backend connector
+    * Ability to provide or enforce custom CA certificate
+    * Optional initialization from environment variables
+* Authorization methods
+    * Token
+    * Username/Password
+    * AppID (register and authenticate) [_deprecated_]
+    * AppRole (register and authenticate)
+* Tokens
+    * Creation and lookup of tokens
+    * TokenBuilder for speaking creation of complex configuraitons
+* Secrets
+    * Read secrets
+    * Write secrets
+    * List secrets
+    * Delete secrets
+    * Renew/revoke leases
+    * Raw secret content or JSON decoding

+## Maven Artifact
+```xml
+<dependency>
+    <groupId>de.stklcode.jvault</groupId>
+    <artifactId>connector</artifactId>
+    <version>0.7.1</version>
+</dependency>
+```
+
+## Usage Examples
+
+### Initialization
+
+```java
+// Instantiate using builder pattern style factory (TLS enabled by default)
+VaultConnector vault = VaultConnectorFactory.httpFactory()
+ .withHost("127.0.0.1")
+ .withPort(8200)
+ .withTLS()
+ .build();
+
+// Instantiate with custom SSL context
+VaultConnector vault = VaultConnectorFactory.httpFactory()
+ .withHost("example.com")
+ .withPort(8200)
+ .withTrustedCA(Paths.get("/path/to/CA.pem"))
+ .build();
+
+// Initialization from environment variables 
+VaultConnector vault = VaultConnectorFactory.httpFactory()
+ .fromEnv()
+ .build();
+```
+
+### Authentication
+
+```java
+// Authenticate with token.
+vault.authToken("01234567-89ab-cdef-0123-456789abcdef");
+
+// Authenticate with username and password.
+vault.authUserPass("username", "p4ssw0rd");
+
+// Authenticate with AppRole (secret - 2nd argument - is optional).
+vault.authAppId("01234567-89ab-cdef-0123-456789abcdef", "fedcba98-7654-3210-fedc-ba9876543210");
+```
+
+### Secret read & write
+
+```java
+// Retrieve secret (prefix "secret/" assumed, use read() to read arbitrary paths)
+String secret = vault.readSecret("some/secret/key").getValue();
+
+// Complex secret.
+Map<String, Object> secretData = vault.readSecret("another/secret/key").getData();
+
+// Write simple secret.
+vault.writeSecret("new/secret/key", "secret value");
+
+// Write complex data to arbitraty path.
+Map<String, Object> map = [...]
+vault.write("any/path/to/write", map);
+
+// Delete secret.
+vault.delete("any/path/to/write");
+```
+
+### Token and role creation
+
+```java
+// Create token using TokenBuilder
+Token token = new TokenBuilder().withId("token id")
+                                .withDisplayName("new test token")
+                                .withPolicies("pol1", "pol2")
+                                .build();
+vault.createToken(token);
+
+// Create AppRole credentials
+vault.createAppRole("testrole", policyList);
+AppRoleSecretResponse secret = vault.createAppRoleSecret("testrole");
+```
