NAME

       openssl-nseq - create or examine a Netscape certificate sequence

SYNOPSIS

       openssl nseq [-help] [-in filename] [-out filename] [-toseq] [-provider name]
       [-provider-path path] [-propquery propq]

DESCRIPTION

       This 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.

       A Netscape certificate sequence is an old Netscape-specific format that can be sometimes
       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 was
       also used by Netscape certificate server.

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.

       -provider name
       -provider-path path
       -propquery propq
           See "Provider Options" in openssl(1), provider(7), and property(7).

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
