如何使用某人的pkcs7签名数据加密邮件？

Question

我需要将XML数据发送给检查数据完整性的应用程序。

demodata.pem（http://privatepaste.com/376402542e）

ca.pem（http://privatepaste.com/85fff7bfe3）

D:\stest\wz\apptest\dist\q\realq>openssl smime -verify -inform pem -in demodata.pem -CAfile ca.pem -out out.xml
Verification successful

D:\stest\wz\apptest\dist\q\realq>

所以我在下面的链接中提到了一条新消息。

D:\stest\wz\apptest\dist\q\realq>openssl pkcs7 -in demodata.pem -inform pem -print_certs -out smime.pem

[smime.pem]

但正如您所见，验证失败。

那么如何从某人的数据中制作签名数据呢？有可能吗？
