# NAME

openssl-nseq - create or examine a Netscape certificate sequence

# SYNOPSIS

openssl nseq [-help] [-in filename] [-out filename] [-toseq] [-provider name] [-provider-path path] [-provparam [name:]key=value] [-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
-provparam [name:]key=value
-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
