PI33760: SHA-2 SIGNATURE ALGORITHM CANNOT BE SPECIFIED FOR SAML TOKEN IN SAMLISSUERCONFIG.PROPERTIES OR WS-SECURITY BINDINGS

Fixes are available

APAR status

Closed as new function.

Error description

Allow signing of a self-issued SAML token using the SHA-2
signature algorithm.

Although this is arelady supported, its use is only externalized
through APIs.

This option should be available through the
SAMLIssuerConfig.properties file and WS-Security policy
bindings.

****************************************************************
There is currently support to sign a SAML token using the
SHA-2 signature algorithm,
http://www.w3.org/2001/04/xmldsig-more#rsa-sha256.  However,
you can only do this using the WSS APIs.  There needs to be a
way to do this using the SAMLIsseuerConfig.properties file or
the WS-Security policy bindings.

Problem conclusion

The WS-Security runtime is updated so that you can specify in
the SAMLIssuerConfig.properties file or WS-Security policy
bindings to use the SHA-2 signature algorithm when signing a
SAML token.

The following property is added to SAMLIssuerConfig.properties
file:

UseSha2ForSignature

The following property is added to the WS-Security policy
bindings and should be set in the SAML token generator
callback handler.  This property can only be used on WebSphere
Application Server v8 and later.

com.ibm.wsspi.wssecurity.saml.config.issuer.UseSha2ForSignature

The values for these properties are true and false.  They
default to false.

The fix for this APAR is currently targeted for inclusion in
fix packs 7.0.0.39, 8.0.0.11 and 8.5.5.6.  Please refer to the
