java - keytool 在单个文件中导入多个证书

Question

如何使用 keytool [to cert store] 在单个文件中导入多个证书？

keytool -importcert 只导入第一个。

Answer 1

一个 bash 脚本，它将从 PEM 文件中导入所有证书：

#!/bin/bash
PEM_FILE=$1
PASSWORD=$2
KEYSTORE=$3
# number of certs in the PEM file
CERTS=$(grep 'END CERTIFICATE' $PEM_FILE| wc -l)

# For every cert in the PEM file, extract it and import into the JKS keystore
# awk command: step 1, if line is in the desired cert, print the line
#              step 2, increment counter when last line of cert is found
for N in $(seq 0 $(($CERTS - 1))); do
  ALIAS="${PEM_FILE%.*}-$N"
  cat $PEM_FILE |
    awk "n==$N { print }; /END CERTIFICATE/ { n++ }" |
    keytool -noprompt -import -trustcacerts \
            -alias $ALIAS -keystore $KEYSTORE -storepass $PASSWORD
done

例如：

./jks_import_pem TrustedCAs.PEM changeit truststore.jks

Answer 2

如果要包含 CA 证书，则应添加该-trustcacerts选项。

如果您在一个 PEM 文件中有多个证书链，则必须拆分该文件。

Answer 3

您可以简单地使用免费且易于使用的 GUI Tool Keystore Explorer 来导入和管理多个证书。

Answer 4

我想做同样的事情，但显然只有在您导入密钥时才有可能：

有两种类型的条目 - 密钥条目和受信任的证书条目，只有密钥条目可以包含附加到它的证书“链”。受信任的证书条目都是单个证书条目。

我什至尝试先转换为 PKCS#7 格式，但由于上述原因或我的 keytool 版本太旧，它没有奏效。

所以必须首先将文件拆分为单独的证书：

cat certchain.pem | awk 'split_after==1{n++;split_after=0} /-----END CERTIFICATE-----/ {split_after=1} {print > ("cert" n ".pem")}'

( https://serverfault.com/q/391396/58568 )

然后分别导入每一个。

Answer 5

您可以使用 p11-kit 工具快速完成此操作。唯一的限制是它从 /etc/pki/ca-trust/source/ 读取证书

/usr/bin/p11-kit extract --format=java-cacerts --filter=ca-anchors \
                --overwrite --purpose server-auth $DEST/java/cacerts

Answer 6

给出的答案并不是真正的 Ansible 解决方案，更像是替代方案。

我在下面写的内容适用于第一个证书，但它不是循环的。有任何想法吗？

    java_install_keystore_cert: true
    java_keystore_certs: "{{ apps.jira.keystore_certs }}"
    java_keystore_cert_alias: test

apps:
  jira:
    keystore_certs:
      - certName: xyz.xxx.com
        certFileName: xyz.xxx.com.pem
      - certName: xxx.com
        certFileName: xxx.com.pem

- name: Copy SSL certificate to remote server
  copy:
    src: "{{ java_keystore_certs[0].certFileName }}"
    #src: "{{ java_keystore_cert_file }}"
    dest: /tmp/
  when: java_install_keystore_cert|default(false)

- name: Determine Java cacerts keystore location
  find:
    paths: "{{ java_home }}/"
    patterns: 'cacerts'
    recurse: yes
  register: cacerts_file
  when: java_install_keystore_cert|default(false)

- name: Import SSL certificate to Java cacerts keystore
  java_cert:
    cert_alias: "{{ java_keystore_cert_alias }}"
    #cert_path: "/tmp/{{ java_keystore_cert_file }}"
    cert_path: "/tmp/{{ java_keystore_certs[0].certFileName }}"
    keystore_path: "{{ cacerts_file.files[0].path }}"
    keystore_pass: changeit
    executable: "{{ java_home }}/bin/keytool"
    state: present
  when: java_install_keystore_cert|default(false) and cacerts_file is defined

Answer 7

我还切换到了一个不仅仅是 Ansible 解决方案......

  copy:
    src: "{{ java_keystore_cert_file }}"
    dest: /tmp/
  when: java_install_keystore_cert|default(false)

- name: Determine Java keystore (cacerts) location
  find:
    paths: "{{ java_home }}/"
    patterns: 'cacerts'
    recurse: yes
  register: cacerts_file
  when: java_install_keystore_cert|default(false)

# Not using the java_cert module (anymore) since that imports the first certificate only

# Always use .pem (simply rename .crt or .cert to .pem if needed)
# The .pem file should contain one or more public certificates, no private key(s) or chain
- name: Transfer the import certificate script
  copy:
    src: files/scripts/importcert.sh
    dest: /tmp/importcert.sh
    mode: 0700
  when: java_install_keystore_cert|default(false) and cacerts_file is defined

- name: Import certificate to Java keystore
  command: sh /tmp/importcert.sh "/tmp/{{ java_keystore_cert_file }}" "{{ java_home }}/bin/keytool" changeit "{{ cacerts_file.files[0].path }}"
  when: java_install_keystore_cert|default(false) and cacerts_file is defined

#!/bin/bash
PEM_FILE=$1
KEYTOOL=$2
PASSWORD=$3
KEYSTORE=$4
# number of certs in the PEM file
CERTS=$(grep 'END CERTIFICATE' $PEM_FILE| wc -l)

# For every cert in the PEM file, extract it and import into the JKS keystore
# awk command: step 1, if line is in the desired cert, print the line
#              step 2, increment counter when last line of cert is found
for N in $(seq 0 $(($CERTS - 1))); do
  ALIAS="${PEM_FILE%.*}-$N"
  cat $PEM_FILE |
    awk "n==$N { print }; /END CERTIFICATE/ { n++ }" |
    $KEYTOOL -noprompt -import -trustcacerts \
            -alias $ALIAS -keystore $KEYSTORE -storepass $PASSWORD
done
