前提:要有android廠家提供的platform.x509.pem和platform.pk8
工具:openssl和keytool,請確保在path中

openssl pkcs8 -inform DER -nocrypt -in "platform.pk8" -out "key.tmp"

openssl pkcs12 -export -in "platform.x509.pem" -inkey "key.tmp" -out "p12.tmp" -password pass:"這裡提供密碼" -name "wipc"

keytool -importkeystore -deststorepass "這裡提供密碼" -destkeystore "輸出.keystore" -srckeystore "p12.tmp" -srcstoretype PKCS12 -srcstorepass "這裡提供密碼"

然後在build.gradle中
    signingConfigs {
        jjy {
            keyAlias 'wipc'
            keyPassword '這裡提供密碼'
            storeFile file('D:/bear/tool/monitor/sign/輸出.keystore')
            storePassword '這裡提供密碼'
        }
    }
