title: 'Configuration'
---

The main configuration file for *dav* is `$HOME/.dav/config.xml` and is used for configuring repositories, proxies and encryption keys. This configuration is also used by *dav-sync*. The file is created automaticaly if it doesn't exist.

The *config.xml* file is an XML file with `<configuration>` as root element. The `<configuration>` element can have the following child elements: `<repository>`, `<http-proxy>`, `<https-proxy>`, `<key>`, `<namespace>`

## repository

This element is used to configure a repository. A repository must have a unique name to identify the repository and a url pointing to the root collection for this repository.

Required child elements: `<name>`, `<url>` \
Optional elements: `<user>`, `<password>`, `<default-key>`, `<full-encryption>`, `<content-encryption>`, `<decrypt-content>`, `<decrypt-name>`, `<cert>`, `<verification>`, `<ssl-version>`, `<authmethods>`

### name

Unique repository identifer.

Type: string \
Example: `<name>myrepo</name>`

### url

The url must point to a valid WebDAV compilant collection.

Type: url \
Example: `<url>https://example.com/webdav/repo1/</url>`

### user

User used for authentication

Type: string \
Example: `<user>alice</user>`

### password

A base64 encoded password used for authentication.

Type: base64 string \
Example: `<password>MTIzNDU2Nzg=</password>`

### default-key

Identifer of the key used by default for encryption. There must be a configured key with this name.

Type: string \
Example: `<default-key>mykey</default-key>`

### full-encryption

If this element has the value of true, content and resource name encryption/decryption is enabled. Resources are only encrypted if the repository has a default-key or a key is specified via command line option. Because encryption and decryption is disabled by default, `false` has no effect for this element. 

Type: boolean \
Default: false \
Example: `<full-encryption>true</full-encryption>`

### content-encryption

This element enables only content encryption and decryption. A value of `false` disables content encryption, but it does not disables content decryption, if this is enabled with `<decrypt-content>`.

Type: boolean \
Default: false \
Example: `<content-encryption>true</content-encryption>`

### decrypt-content

Controls only the decryption of content. If `true` content is decrypted.

Type: boolean \
Default false \
Example: `<decrypt-content>true</decrypt-content>`

### decrypt-name

Controls only the decryption of resource names. If `true` resource names are decrypted. This effects path to url resolution.

Type: boolean \
Default: false \
Example: `<decrypt-name>true</decrypt-name>`

### cert

Path to a file containing certificates to verify the TLS connection to the server.

Type: string \
Example: `<cert>/etc/certs/cabundle.pem</cert>`

Note: This element does the same as curl's `--cacert` option.

### verification

This element can disable TLS certificate verification. 

Type: boolean \
Default: true \
Example: `<verification>false</verification>`

### ssl-version

Specifies the SSL version to attempt to use. The value must be one of this strings: TLSv1, TLSv1.0, TLSv1.1, TLSv1.2, SSLv2, SSLv3

Type: ssl version enum \
Example: `<ssl-version>TLSv1.2</ssl-version>`

### authmethods

Controls which http authentication methods are used. Multiple methods can be used. The value must be one or more authentication methods separated by space. Valid authentication methods are: basic, digest, negotiate, ntlm, any, none

Type: list of authmethod

Default: basic \
Example: `<authmethods>basic digest</authmethods>`

## key

The `<key>` element configures a key used for encryption. A key must have a unique name, which is stored in the properties of encrypted resources. To decrypt resources, dav looks for configured keys with this name, therefore the name of the key should never changed and must be the same on all hosts accessing the same repository.

Required child elements: `<name>`, `<file>` \
Optional elements: `<type>`

### name

Unique key identifer.

Type: string \
Example: `<name>key1</name>`

### file

Path to the content of the key. The file should contain 32 (aes256) or 16 (aes128) bytes. If value is not an absolut path, it must be relative to the dav config directory *$HOME/.dav/*.

Type: string \
Example: `<path>keys/key1.bin</path>`

### type

Specifies the key type. Valid values are `aes128` or `aes256`.

Type: aes type enum \
Default: aes256 \
Example: `<type>aes128</type>`

## http-proxy / https-proxy

Configuration for http and https proxies is the same. Both use the same elements, but https-proxy expects an https url.

Required child elements: `<url>` \
Optional elements: `<user>`, `<password>`, `<no>`

### url

Specifies the proxy url.

Type: url \
Example: `<url>http://myproxy/</url>`

### user

User used for authentication with the proxy.

Type: string \
Example: `<user>alice</user>`

### password

A base64 encoded password used for authentication.

Type: base64 string \
Example: `<password>MTIzNDU2Nzg=</password>`

### no

A comma separated list of all hosts that should not be accessed through the proxy.

Type: string \
Example: `<no>host1, host2, host3</no>`

## namespace

Configures an XML-namespace with prefix and uri. The prefix can be used with commands like `get-property`. The element must have the `prefix` and the `uri` attribute.

Type: no value
Example: `<namespace prefix="e" uri="http://example.com/" />`

## Example 1: minimal repository configuration

A minimal configuration for a repository. If no user and/or password are configured, dav prompts for authentication informations if required.
	
	<configuration>
		<repository>
			<name>myrepo</name>
			<url>https://example.com/path/to/repo/</url>
		</repository>
	</configuration>

## Example 2: repository with authentication informations

A typical configuration for easy accessing a repository without authentication prompt.

	<configuration>
		<repository>
			<name>myrepo</name>
			<url>https://example.com/path/to/repo/</url>
			<user>alice</user>
			<password>MTIzNDU2Nzg=</password>
		</repository>
	</configuration>

## Example 3: repository with full encryption

A configuration for a full encrypted repository. Additionally to the repository a key must be configured.

	<configuration>
		<repository>
			<name>myrepo</name>
			<url>https://example.com/path/to/repo/</url>
			<user>alice</user>
			<password>MTIzNDU2Nzg=</password>
			<full-encryption>true</full-encryption>
			<default-key>mykey1</default-key>
		</repository>
		
		<key>
			<name>mykey1</name>
			<file>keys/mykey1</file>
			<type>aes256</type>
		</key>
	</configuration>
