5 nseq - create or examine a netscape certificate sequence
17 The B<nseq> command takes a file containing a Netscape certificate
18 sequence and prints out the certificates contained in it or takes a
19 file of certificates and converts it into a Netscape certificate
22 =head1 COMMAND OPTIONS
28 Print out a usage message.
32 This specifies the input filename to read or standard input if this
33 option is not specified.
35 =item B<-out filename>
37 specifies the output filename or standard output by default.
41 normally a Netscape certificate sequence will be input and the output
42 is the certificates contained in it. With the B<-toseq> option the
43 situation is reversed: a Netscape certificate sequence is created from
44 a file of certificates.
50 Output the certificates in a Netscape certificate sequence
52 openssl nseq -in nseq.pem -out certs.pem
54 Create a Netscape certificate sequence
56 openssl nseq -in certs.pem -toseq -out nseq.pem
60 The B<PEM> encoded form uses the same headers and footers as a certificate:
62 -----BEGIN CERTIFICATE-----
63 -----END CERTIFICATE-----
65 A Netscape certificate sequence is a Netscape specific form that can be sent
66 to browsers as an alternative to the standard PKCS#7 format when several
67 certificates are sent to the browser: for example during certificate enrollment.
68 It is used by Netscape certificate server for example.
72 This program needs a few more options: like allowing DER or PEM input and
73 output files and allowing multiple certificate files to be used.
