| NAnt  Help  Task Reference  <delay-sign> | v0.85 | 
Signs delay-signed .NET Assemblies, or re-signs existing assemblies.
 The delay-signing mechanism takes a fileset (named targets) and either a keyfile attribute for a file containing the public and private keys, or keycontainer to name a key container. 
| Attribute | Type | Description | Required | 
|---|---|---|---|
| keycontainer | string | Specifies the key container. | False | 
| keyfile | file | Specifies the filesystem path to the signing key. | False | 
| failonerror | bool | Determines if task failure stops the build, or is just reported. The default is true. | False | 
| if | bool | If true then the task will be executed; otherwise, skipped. The default is true. | False | 
| timeout | int | The maximum amount of time the application is allowed to execute, expressed in milliseconds. Defaults to no time-out. | False | 
| unless | bool | Opposite of if. If false then the task will be executed; otherwise, skipped. The default is false. | False | 
| verbose | bool | Determines whether the task should report detailed build log messages. The default is false. | False | 
| Attribute | Type | Description | Required | 
|---|---|---|---|
| exename | string | The name of the executable that should be used to launch the external program. | False | 
| useruntimeengine | bool | Specifies whether the external program should be executed using a runtime engine, if configured. The default is false. | False | 
Represents a command-line argument.
| Attribute | Type | Description | Required | 
|---|---|---|---|
| dir | directory | The value for a directory-based command-line argument; will be replaced with the absolute path of the directory. | False | 
| file | file | The name of a file as a single command-line argument; will be replaced with the absolute filename of the file. | False | 
| if | bool | Indicates if the argument should be passed to the external program. If true then the argument will be passed; otherwise, skipped. The default is true. | False | 
| line | string | List of command-line arguments; will be passed to the executable as is. | False | 
| path | <path> | The value for a PATH-like command-line argument; you can use :or;as path separators and NAnt will convert it to the platform's local conventions, while resolving references to environment variables. | False | 
| unless | bool | Indicates if the argument should not be passed to the external program. If false then the argument will be passed; otherwise, skipped. The default is false. | False | 
| value | string | A single command-line argument; can contain space characters. | False | 
A single command-line argument containing a space character.
<arg value="-l -a" />
    Two separate command-line arguments.
<arg line="-l -a" />
     A single command-line argument with the value \dir;\dir2;\dir3 on DOS-based systems and /dir:/dir2:/dir3 on Unix-like systems. 
<arg path="/dir;/dir2:\dir3" />
    Sign partially-signed foo.dll with bar.snk.
<delay-sign keyfile="bar.snk" verbose="false">
    <targets>
        <include name="foo.dll" />
    </targets>
