# Services Administration - How to: Enable SOAP Digital Signatures

Some **SOAP (Simple Object Access Protocol)** **APIs** require that you attach a SOAP digital signature to a service. A digital signature is a value computed with a cryptographic algorithm. When that value is sent as part of a request, it lets the recipient verify the security and integrity of the incoming data.

The Enable SOAP Digital Signature checkbox lets you attach a digital signature to any service that might use SOAP. For example, services using the WSSE Username Token Profile or SOAP Custom Header authentication types. When a service request comes in, the authentication processes. Then, the digital signature is added to the XML of the request body object.

> [!TIP]
> You must specify a signing, digest, and canonicalization algorithm to set up the digital signature. To learn about each algorithm, see the W3C XML Signature Syntax and Processing documentation here: [https://www.w3.org/TR/xmldsig-core1/#sec-AlgID](https://www.w3.org/TR/xmldsig-core1/#sec-AlgID). To learn more about SOAP digital signatures, see the W3C documentation here: [https://www.w3.org/TR/SOAP-dsig/](https://www.w3.org/TR/SOAP-dsig/).

The following instructions will help you add a SOAP digital signature to a service.

> [!NOTE]
> These instructions assume you already set up a service that requires a SOAP digital signature.

1. Set **Enable SOAP Digital Signature** to (**checked**).
2. In the **SOAP Digital Signature --- PFX or PKCS12 Encoded (hex) Private Key and Certificate Chain** field, copy and paste the digital signature key.
3. If required, copy and paste the passphrase into the **SOAP Digital Signature --- PFX Passphrase** field.
4. In the **SOAP Digital Signature --- Signing Algorithm** field, enter the signing algorithm.

5. In the **SOAP Digital Signature --- Digest Algorithm** field, enter the digest algorithm.

6. In the **SOAP Digital Signature --- Canonicalization Algorithm** field, enter the canonicalization algorithm.
