Getting certificate details from an apk
提问by Ravi Vyas
How do i go about getting the details of the certificate an apk was signed with. I have a bunch of apks signed with different certificate and I am trying to group them based on their certificate.
我如何获取与 apk 签名的证书的详细信息。我有一堆用不同证书签名的apk，我试图根据他们的证书对它们进行分组。
I can get the certificate expiry details using the jarsigner and complete my task but I was curious if I can get any more details or extract the public key ( I believe it stored in META-INF/cert.RSA but its not readable )
我可以使用 jarsigner 获取证书到期详细信息并完成我的任务，但我很好奇是否可以获得更多详细信息或提取公钥（我相信它存储在 META-INF/cert.RSA 但它不可读）

Try the following:
请尝试以下操作：
openssl pkcs7 -inform DER -in CERT.RSA -noout -print_certs -text

unzip -p Name-of-apk.apk META-INF/CERT.RSA | keytool -printcertis what I used .
unzip -p Name-of-apk.apk META-INF/CERT.RSA | keytool -printcert是我用的。
It produces information such as the owner , issuer , serial number , valid through, certificate finger prints , signature algorithms and version .
它产生诸如所有者、发行者、序列号、有效通过、证书指纹、签名算法和版本等信息。

Based on the existing answers, here's the command line for on-the-fly usage of openssl(unzip & pipe the cert instead of defining an -infileoption):
基于现有的答案，这里是即时使用的命令行openssl（解压缩和管道证书，而不是定义一个-infile选项）：
unzip -p App.apk META-INF/CERT.RSA |openssl pkcs7 -inform DER -noout -print_certs -text

without unpacking you can use ApkSigner from Android SDK and following:
无需解包，您就可以使用 Android SDK 中的 ApkSigner 和以下内容：
apksigner.jar verify --print-certs myApplication.apk
