# Class SignOperation

java.lang.Object
org.gradle.plugins.signing.SignOperation

All Implemented Interfaces:
  `SignatureSpec`

public abstract class SignOperation extends Object implements SignatureSpec
A sign operation creates digital signatures for one or more files or `publish artifacts`.

The external representation of the signature is specified by the `signature type property`, while the `signatory` property specifies who is to sign.

A sign operation manages one or more `Signature` objects. The `sign` methods are used to register things to generate signatures for. The `execute()` method generates the signatures for all of the registered items at that time.

  - ### setSignatureType

    public void setSignatureType(SignatureType signatureType)
    Description copied from interface: `SignatureSpec`
    Sets the signature representation that the signatures will be produced as.
    Specified by:
      `setSignatureType` in interface `SignatureSpec`
    Parameters:
      `signatureType` - the signature type to use

  - ### getSignatureType

    public SignatureType getSignatureType()
    Description copied from interface: `SignatureSpec`
    The signature representation that will be created.
    Specified by:
      `getSignatureType` in interface `SignatureSpec`
    Returns:
      the signature type, or `null` if none specified.

  - ### setSignatory

    public void setSignatory(Signatory signatory)
    Description copied from interface: `SignatureSpec`
    Sets the signatory that will be signing the input.
    Specified by:
      `setSignatory` in interface `SignatureSpec`
    Parameters:
      `signatory` - The signatory

  - ### getSignatory

    public Signatory getSignatory()
    Description copied from interface: `SignatureSpec`
    The signatory that will be performing the signing.
    Specified by:
      `getSignatory` in interface `SignatureSpec`
    Returns:
      the signatory, or `null` if none specified.

  - ### setRequired

    public void setRequired(boolean required)
    Description copied from interface: `SignatureSpec`
    Whether or not it is required that this signature be generated.
    Specified by:
      `setRequired` in interface `SignatureSpec`
    Parameters:
      `required` - Whether or not it is required that this signature be generated.
    See Also:
      - `SignatureSpec.isRequired()`

  - ### isRequired

    public boolean isRequired()
    Description copied from interface: `SignatureSpec`
    Whether or not it is required that this signature be generated. A signature may not be able to be generated if a signatory and/or a signature type have not been specified. If it is required and cannot be generated, an exception will be thrown. Otherwise, it will not be generated.
    Specified by:
      `isRequired` in interface `SignatureSpec`

  - ### sign

    public SignOperation sign(PublishArtifact... artifacts)
    Registers signatures for the given artifacts.
    Returns:
      this
    See Also:
      - `Signature(File, SignatureSpec, Object...)`

  - ### sign

    public SignOperation sign(File... files)
    Registers signatures for the given files.
    Returns:
      this

  - ### configure

    public SignOperation configure(Closure closure)
    Executes the given closure against this object.

  - ### execute

    public SignOperation execute()
    Generates actual signature files for all of the registered signatures.

    This method can be called multiple times, with the signatures being generated with their current configuration each time.

    Returns:
      this

    Returns the single registered signature.
    Returns:
      The signature.
    Throws:
      `IllegalStateException` - if there is not exactly one registered signature.
