Can I encrypt, decrypt, sign or verify data using PKCS#7 without Bouncy Castle?

Question

I want to encrypt, decrypt, sign and verify data using PKCS#7 Cryptographic Message Syntax. I saw sample code for this with Bouncy Castle. I want to know can I do this without using the Bouncy Castle libraries?

Answer 1

There is no support for PKCS7 messages in the standard Java libraries. There is no reason not to use an existing implementation like Bouncycastle. It has such a liberal license you can probably just grab it and say you wrote it.

Answer 2

使用JCE和PKCS5应该具有完全兼容的结果。
