Issue
Can FIM be forced to create SAML assertions signed with SHA256 instead of SHA1? The SAML specs only mention SHA1 .
Resolution
FIM doesn??t have capability to select higher strength algorithms??
It supports only following algorithms depending upon the key algorithm of keystore available for signing.
DSA: ??http://www.w3.org/2000/09/xmldsig#dsa-sha1??
RSA: ??http://www.w3.org/2000/09/xmldsig#rsa-sha1??
The SAML spec :
5.4.1 Signing Formats and Algorithms
SAML processors SHOULD support the use of RSA signing and verification for public key
operations in accordance with the algorithm identified by http://www.w3.org/2000/09/xmldsig#rsa-sha1.
