NAME

       openssl-nseq, nseq - create or examine a Netscape certificate sequence

SYNOPSIS

       openssl nseq [-help] [-in filename] [-out filename] [-toseq]

DESCRIPTION

       The nseq command takes a file containing a Netscape certificate sequence and prints out the certificates
       contained in it or takes a file of certificates and converts it into a Netscape certificate sequence.

OPTIONS

       -help
           Print out a usage message.

       -in filename
           This specifies the input filename to read or standard input if this option is not specified.

       -out filename
           Specifies the output filename or standard output by default.

       -toseq
           Normally  a  Netscape certificate sequence will be input and the output is the certificates contained
           in it. With the -toseq option the situation is reversed: a Netscape certificate sequence  is  created
           from a file of certificates.

EXAMPLES

       Output the certificates in a Netscape certificate sequence

        openssl nseq -in nseq.pem -out certs.pem

       Create a Netscape certificate sequence

        openssl nseq -in certs.pem -toseq -out nseq.pem

NOTES

       The PEM encoded form uses the same headers and footers as a certificate:

        -----BEGIN CERTIFICATE-----

        -----END CERTIFICATE-----
       A  Netscape  certificate  sequence  is  a  Netscape  specific  format  that can be sent to browsers as an
       alternative to the standard PKCS#7 format when several certificates are sent to the browser: for  example
       during certificate enrollment.  It is used by Netscape certificate server for example.

BUGS

       This  program  needs  a  few  more  options: like allowing DER or PEM input and output files and allowing
       multiple certificate files to be used.
