How could I Use AES/CBC/PKCS5Padding about encrypt

[lonely4flow]

And how to use public RSA key to decode data?
when i use public key decrypt,it shows message:
Bad state: Can't decrypt without a private key, null given.

Sorry, there is no support for PKCS5 on PointyCastle, so I can not wrap it in Encrypt.

Public keys on asymmetric cryptography, like RSA, are intended to be used only for encryption, that is why it can be public, because it won't be decrypting nothing, only encrypting.

that‘s ok,I have use flutter plugin package solve this problem.
using public key to decryp data maybe not good,but it is decided by our architect，I can do nothing but follow😁

Pkcs7 should work for a server with PKCS5 padding.

I just tested it for my server which uses PKCS5 while using Pkcs7 padding at encryption.

Pointy castle guys say they both should work the same.
