6 nseq - create or examine a Netscape certificate sequence
18 The B<nseq> command takes a file containing a Netscape certificate
19 sequence and prints out the certificates contained in it or takes a
20 file of certificates and converts it into a Netscape certificate
29 Print out a usage message.
33 This specifies the input filename to read or standard input if this
34 option is not specified.
36 =item B<-out filename>
38 Specifies the output filename or standard output by default.
42 Normally a Netscape certificate sequence will be input and the output
43 is the certificates contained in it. With the B<-toseq> option the
44 situation is reversed: a Netscape certificate sequence is created from
45 a file of certificates.
51 Output the certificates in a Netscape certificate sequence
53 openssl nseq -in nseq.pem -out certs.pem
55 Create a Netscape certificate sequence
57 openssl nseq -in certs.pem -toseq -out nseq.pem
61 The B<PEM> encoded form uses the same headers and footers as a certificate:
63 -----BEGIN CERTIFICATE-----
64 -----END CERTIFICATE-----
66 A Netscape certificate sequence is a Netscape specific format that can be sent
67 to browsers as an alternative to the standard PKCS#7 format when several
68 certificates are sent to the browser: for example during certificate enrollment.
69 It is used by Netscape certificate server for example.
73 This program needs a few more options: like allowing DER or PEM input and
74 output files and allowing multiple certificate files to be used.
