Documentation

Definition

The XML Security Standard defines following 3 signature methods:

• DSA (required)
• RSA (recommended)
• HMAC (required)

Use

The first two methods are based on X509 keys (certificates), the last (HMAC) method is based on an own secret.

Dependencies

DSA and RSA depend on the settings in the STRUST application. All methods depend on a trust of the other secrets. In case of RSA/DSA you have to add the partner public key in your PSE. In the case of HMAC you have to share the secret with your partner.

Example

RSA:     http://www.w3.org/2000/09/xmldsig#rsa-sha1

DSA: http://www.w3.org/2000/09/xmldsig#dsa-sha1

HMAC: http://www.w3.org/2000/09/xmldsig#hmac-sha1
