C#怎么实现java中PKCS7加密，下面是java的加密方法

[m0_71976881]

public static String sign(byte[] byte_msg, String sender_pri_file_pwd, String sender_pri_file_nm, String sender_cer_file_nm) {
    try {
        char[] keyPassword = (new String(sender_pri_file_pwd)).toCharArray();
        byte[] base64EncodedPrivatekey = FileUtil.read4file(sender_pri_file_nm);
        PrivateKey signerPrivatekey = CryptUtil.decryptPrivateKey(Base64.decode(base64EncodedPrivatekey), keyPassword);
        byte[] base64EncodedCert = FileUtil.read4file(sender_cer_file_nm);
        X509Certificate signerCertificate = CryptUtil.generateX509Certificate(Base64.decode(base64EncodedCert));
        byte[] signature = PKCS7Signature.sign(byte_msg, signerPrivatekey, signerCertificate, (X509Certificate[])null, false);
        String b64StrSignature = new String(Base64.encode(signature));
        return b64StrSignature;
    } catch (Exception var11) {
        var11.printStackTrace();
        return null;
    }
}
