我已经在java卡中生成了密钥对并返回公钥。我在 android 应用程序中再次生成公钥，然后在 android 中生成 CSR

 private byte[] CertReqGeneration()  throws Exception
 {
    if(publickeyobj==null)
        return null;

    String info = "CN=cn, OU=ou, O=o, C=cn, ST=city";
    X500Principal x500 = new X500Principal(info);

    X500Name x500name;
    x500name= X500Name.getInstance(x500.getEncoded());

    CertificationRequestInfo csrInfo = new CertificationRequestInfo(x500name, publickeyobj, new DERSet());

    ASN1EncodableVector v = new ASN1EncodableVector();
    v.add(csrInfo);
    ASN1ObjectIdentifier oid = new ASN1ObjectIdentifier("0.0");
    v.add(new DERSequence(oid));
    v.add(new DERBitString(new byte[] {}));
    byte[] encoded = new DERSequence(v).getEncoded();
    byte[] PKCS10= DataSignGeneration(encoded);

       byte[] encoded = Base64.encode(PKCS10);
      String base64=new String(encoded);
    return  base64;

}

但是当我想在 ca 中发布它时，我收到错误 asn1 bad …
