Hi: I'd like to control what public keys and/or certs are used or usable for verifying data. In particular, I'd like to require that the public key be validated by a cert (i.e., that <sig:KeyValue> supplied unvalidated keys not be usable,and, I'd like to impose certain contraints on any cert used (e.g., validating Issuer, Subject, Usage, etc.). While I could search for a KeyValue node before calling validation, it seems like there may be a better way to accomplish this (below). Additionally, it looks like I could store a new verifyX509 (xmlSecX509VerifyCallback) pointer in the xmlSecKeysMngr struct and intercept the cert verification. Still, since I'm very new to all of this, I'm wondering if there's not simpler/better/more direct ways to accomplish these types of checks. Any suggestions or pointers would be greatly appreciated! It looks like setting the allowedOrigins flag of the xmlSecKeysMngr structure to xmlSecKeyOriginX509 may solve my first problem and ensure that only keys found in a X509 cert will be usable. Correct? I don't see any such short-cut for validating the X509 cert contents other than the verifyX509 override I mentioned earlier. Any other way / better option? Finally, it looks like xmlSecSimpleKeysMngrLoadPemCert() method can be used to load a trusted root certificate for X509 validation from a file. I'd rather not have a seperate file storing this information. Is there any way to load a trusted cert from a memory blob or perhaps from a second XML document/tree? Thanks! Ferrell
