Android-从密钥库导出单个密钥/别名 [英] Android - export single key/alias from keystore

问题描述

我有一个密钥库(JKS)，其中包含许多用于不同应用程序的密钥条目/别名.现在，一个应用程序将移至另一位开发人员，我想为他导出/提取单个密钥/别名.

I have a single keystore (JKS) with a lot of key entries / aliases for different apps in it. Now one app will be moved to another developer and I want to export / extract the single key / alias for him.

> keytool.exe -list -keystore Keystorefile

Keystore-type: JKS
Keystore-provider: SUN

Keystore contains 6 entries

Appname1, 01.07.20XX, PrivateKeyEntry,
certificate-Fingerprint (SHA1): AA:BB:CC:DD:EE:FF:GG:HH:II:JJ:KK:LL:MM:NN:OO:PP:Q

Appname2, 29.05.20XX, PrivateKeyEntry,
certificate-Fingerprint (SHA1): AA:BB:CC:DD:EE:FF:GG:HH:II:JJ:KK:LL:MM:NN:OO:PP:Q
Q:RR:SS:TT
Appname3, 30.09.20XX, PrivateKeyEntry,
certificate-Fingerprint (SHA1): AA:BB:CC:DD:EE:FF:GG:HH:II:JJ:KK:LL:MM:NN:OO:PP:Q
Q:RR:SS:TT
Appname4, 18.02.20XX, PrivateKeyEntry,
certificate-Fingerprint (SHA1): AA:BB:CC:DD:EE:FF:GG:HH:II:JJ:KK:LL:MM:NN:OO:PP:Q
Q:RR:SS:TT
Appname5, 09.08.20XX, PrivateKeyEntry,
certificate-Fingerprint (SHA1): AA:BB:CC:DD:EE:FF:GG:HH:II:JJ:KK:LL:MM:NN:OO:PP:Q
Q:RR:SS:TT
Appname6, 11.02.20XX, PrivateKeyEntry,
certificate-Fingerprint (SHA1): AA:BB:CC:DD:EE:FF:GG:HH:II:JJ:KK:LL:MM:NN:OO:PP:Q
Q:RR:SS:TT

这是我的密钥库的输出，现在我只想导出 Appname2 的密钥.可以将其导入另一个密钥库中.

This is the output of my Keystore, now I want to export only the Key for Appname2. That this can be imported in another Keystore if possible.

谢谢！

推荐答案

这比导出证书(可使用 -exportcert 导出证书)省去一些麻烦，因为您需要使用-importkeystore 并使用您要导出"的密钥创建新的密钥库，即

This is bit less strigforward than exporting certificates (which can be exported with -exportcert) as you need to use -importkeystore and create new keystore with the key you want to "export", i.e.

keytool -importkeystore -srckeystore keystore.jks -destkeystorekeystore.p12 -deststoretype PKCS12 -srcalias ALIAS -deststorepass PASS-destkeypass通过

keytool -importkeystore -srckeystore keystore.jks -destkeystore keystore.p12 -deststoretype PKCS12 -srcalias ALIAS -deststorepass PASS -destkeypass PASS

或者，您可以仅复制当前的密钥库文件，然后从其中删除所有密钥，但要导出的密钥除外.

Alternatively you can just copy your current keystore file and then remove all keys from it but the one you want to export.

您还可以检查 Keystore Explorer 工具
