I think you're right, there's an issue with AKID/SKID in x509 - signkey. (I'm sending this on to [EMAIL PROTECTED], to open a ticket for it.)
Repeat the mantra: "Only the Certifier has AKID == SKID. Certificates have AKID == CA's SKID." Now, forget the mantra, cuz the only exception is self-signed certificates. (which is all a CA's certificate really is, if it's a trust anchor.) Since x509 -signkey is supposed to create self-signed certificates, it's supposed to set AKID == SKID. Now. I'm on OpenSSL 0.9.8e 23 Feb 2007, and I just did the following sequence: mkdir phase1 mkdir phase2 CA.pl -newca (generate demoCA/cacert.pem and demoCA/private/ cakey.pem) (SKID A8:2E, AKID A8:2E) CA.pl -newcert (generate newcert.pem and newkey.pem) (SKID D8:75, AKID D8:75) mv *.pem phase1 CA.pl -newreq (generate newreq.pem and newkey.pem) CA.pl -sign (generate newcert.pem) (SKID FB:9E, AKID A8:2E) mv *.pem phase2 cd phase2 openssl x509 -in newcert.pem -out intermediary.pem -signkey newkey.pem intermediary.pem reports SKID FB:9E, AKID A8:2E. It should set AKID = SKID for -signkey, and so the AKID should be FB:9E. -Kyle H On Oct 24, 2007, at 11:01 PM, Simon McMahon wrote: > Hi, > > cross ref on support list: "Re: refresh validity dates on a > certificate". > > While trying to refresh validity on certs I noticed that "openssl > x509 ... > -signkey filename" modifies the issuer name.
