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.
