i emailed ipad .p12 certificate , installed in settings under settings->profiles->configuration profiles. i tried using following code array of certificates on ipad: secrecord myquery = new secrecord(seckind.identity); secstatuscode resultcode; secrecord[] arrayrecords = seckeychain.queryasrecord(myquery, 10, out resultcode); the resultcode set itemnotfound when returning queryasrecord(). tried creating myquery as: secrecord myquery = new secrecord(seckind.certificate); but caused resultcode set itemnotfound. how use seckeychain.queryasrecord() list of installed certificates? the keychain not useful think is. keychain gives access certificates manually added, wont give access system ones. or @ least, have never found way of doing , googling few months ago turned out no answers problem.
