Verifying consumer signing information to protect message integrity using WSS APIs


We can verify the signing information to protect message integrity for the response (client side) consumer binding. Signing information includes the signature and the signed parts for the generator side as well as signature verification and verify parts for the consumer side. To keep the integrity of the message, digital signatures are typically applied.

Verify the signature and signed parts information has been configured. The signature verification information must match what was configured on the generator side.

Integrity refers to digital signature while confidentiality refers to encryption. Integrity is provided by applying a digital signature to a SOAP message. To configure the signing information to protect message integrity, first digitally sign and then verify the signature for the SOAP messages. Integrity decreases the risk of data modification when you transmit data across a network.

Also, message integrity is provided by verifying the digitally signed body, time stamp, and WS-Addressing headers using the signature verification algorithm methods. The WSS APIs specify which algorithm is to be used to verify the certificate. The signature algorithms specify the Uniform Resource Identifiers (URI) of the signature verification method. WAS supports several pre-configured verification algorithm methods. Use the following interfaces to configure WS-Security and to protect SOAP message integrity:

Perform the following verification tasks, using the WSS APIs, to configure the signing information and to protect message integrity for the consumer binding.
