OPENSSL-NSEQ(1SSL)                             OpenSSL                            OPENSSL-NSEQ(1SSL)



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
