# CMSSignerStatus

The constants that indicate the status of the signature and signer information in a signed message.

```
enum CMSSignerStatus
```

## Overview

These are obtained using the [`CMSDecoderCopySignerStatus(_:_:_:_:_:_:_:)`](/documentation/Security/CMSDecoderCopySignerStatus(_:_:_:_:_:_:_:)) function.

## Topics

### Constants

[`CMSSignerStatus.unsigned`](/documentation/Security/CMSSignerStatus/unsigned)

The message was not signed.

[`CMSSignerStatus.valid`](/documentation/Security/CMSSignerStatus/valid)

The message was signed and both the signature and the signer certificate have been verified.

[`CMSSignerStatus.needsDetachedContent`](/documentation/Security/CMSSignerStatus/needsDetachedContent)

The message was signed but has detached content. You must call the [`CMSDecoderSetDetachedContent(_:_:)`](/documentation/Security/CMSDecoderSetDetachedContent(_:_:)) function before ascertaining the signature status.

[`CMSSignerStatus.invalidSignature`](/documentation/Security/CMSSignerStatus/invalidSignature)

The message was signed but the signature is invalid.

[`CMSSignerStatus.invalidCert`](/documentation/Security/CMSSignerStatus/invalidCert)

The message was signed but the signer’s certificate could not be verified.

[`CMSSignerStatus.invalidIndex`](/documentation/Security/CMSSignerStatus/invalidIndex)

The specified value for the signer index (`signerIndex` parameter) is greater than the number of signers of the message minus one (`signerIndex > (numSigners – 1)`).
