Was the file malformed? I have a hard time imagining any non-empty set of well-formed certs in that file causing the problem you describe. Did the file contain any PEM X.509 certificates? Does: $ cafile=<your former CAfile> $ openssl crl2pkcs7 -nocrl -certfile "$cafile" | openssl pkcs7 -print_certs -noout | grep -c '^issuer=' report any errors to stderr? How many issuers were reported by grep? -- Viktor.
