New CLI commands have been added to import/export certificates and private keys into/from the client security database. The CLI can also be used to generate the file needed by Python client library for client certificate authentication. -- Endi S. Dewata

From 6b60698a2c35cb530a379a2970f7fc11af7e5798 Mon Sep 17 00:00:00 2001 From: "Endi S. Dewata" <edewata(a)redhat.com&gt; Date: Mon, 6 Oct 2014 12:20:42 -0400 Subject: [PATCH] Added CLI to import/export certificates with private keys. New CLI commands have been added to import/export certificates and private keys into/from the client security database. The CLI can also be used to generate the file needed by Python client library for client certificate authentication. --- .../src/com/netscape/certsrv/client/PKIClient.java | 6 + base/java-tools/man/man1/pki-client.1 | 44 +++- .../src/com/netscape/cmstools/cli/MainCLI.java | 4 +- .../com/netscape/cmstools/client/ClientCLI.java | 2 + .../cmstools/client/ClientCertImportCLI.java | 172 +++++++++++--- .../cmstools/client/ClientCertModifyCLI.java | 126 ++++++++++ .../cmstools/client/ClientCertShowCLI.java | 256 +++++++++++++++++++++ 7 files changed, 578 insertions(+), 32 deletions(-) create mode 100644 base/java-tools/src/com/netscape/cmstools/client/ClientCertModifyCLI.java create mode 100644 base/java-tools/src/com/netscape/cmstools/client/ClientCertShowCLI.java diff --git a/base/common/src/com/netscape/certsrv/client/PKIClient.java b/base/common/src/com/netscape/certsrv/client/PKIClient.java index c23e8b600b125d0a2da14dcec1880fb05598f42a..e06b4db54569d5ed46fdd138af3ded93e6fd1878 100644 --- a/base/common/src/com/netscape/certsrv/client/PKIClient.java +++ b/base/common/src/com/netscape/certsrv/client/PKIClient.java @@ -104,6 +104,12 @@ public class PKIClient { this.verbose = verbose; } + public X509Certificate getCert(String nickname) + throws NotInitializedException, ObjectNotFoundException, TokenException { + CryptoManager manager = CryptoManager.getInstance(); + return manager.findCertByNickname(nickname); + } + public X509Certificate[] getCerts() throws NotInitializedException { CryptoManager manager = CryptoManager.getInstance(); return manager.getPermCerts(); diff --git a/base/java-tools/man/man1/pki-client.1 b/base/java-tools/man/man1/pki-client.1 index 0364f84efb97a7263194799bf44ce625519311e1..87da255ff0fd5e385aec845f9364ad977d9f7aad 100644 --- a/base/java-tools/man/man1/pki-client.1 +++ b/base/java-tools/man/man1/pki-client.1 @@ -22,7 +22,9 @@ pki-client \- Command-Line Interface for managing the security database on Certi \fBpki\fR [CLI options] \fBclient-init\fR [command options] \fBpki\fR [CLI options] \fBclient-cert-find\fR [command options] \fBpki\fR [CLI options] \fBclient-cert-request\fR <subject DN> [command options] -\fBpki\fR [CLI options] \fBclient-cert-import\fR <nickname> [command options] +\fBpki\fR [CLI options] \fBclient-cert-import\fR [nickname] [command options] +\fBpki\fR [CLI options] \fBclient-cert-mod\fR <nickname> [command options] +\fBpki\fR [CLI options] \fBclient-cert-show\fR <nickname> [command options] \fBpki\fR [CLI options] \fBclient-cert-del\fR <nickname> [command options] .fi @@ -50,7 +52,17 @@ This command is to list certificates in the client security database.
