Getting EOFException while trying to read from SSLSocket
- by Isac
Hi, I am developing a SSL client that will do a simple request to a SSL server and wait for the response. The SSL handshake and the writing goes OK but I can't READ data from the socket. I turned on the debug of java.net.ssl and got the following:
[..]
main, READ: TLSv1 Change Cipher Spec, length = 1
[Raw read]: length = 5
0000: 16 03 01 00 20 ....
[Raw read]: length = 32
[..]
main, READ: TLSv1 Handshake, length = 32
Padded plaintext after DECRYPTION: len = 32
[..]
* Finished
verify_data: { 29, 1, 139, 226, 25, 1, 96, 254, 176, 51, 206, 35 }
%% Didn't cache non-resumable client session: [Session-1, SSL_RSA_WITH_RC4_128_MD5]

main, SEND TLSv1 ALERT: warning, description = close_notify

main, WRITE: TLSv1 Alert, length = 18
[Raw write]: length = 23
[..]
main, called close()
main, called closeInternal(true)
main, called close()
main, called closeInternal(true)
The [..] are the certificate chain.
Here is a code snippet:
try {
System.setProperty("javax.net.debug","all");
/*
* Set up a key manager for client authentication
* if asked by the server. Use the implementation's
* default TrustStore and secureRandom routines.
*/
SSLSocketFactory factory = null;
try {
SSLContext ctx;
KeyManagerFactory kmf;
KeyStore ks;
char[] passphrase = "importkey".toCharArray();
ctx = SSLContext.getInstance("TLS");
kmf = KeyManagerFactory.getInstance("SunX509");
ks = KeyStore.getInstance("JKS");
ks.load(new FileInputStream("keystore.jks"), passphrase);
kmf.init(ks, passphrase);
ctx.init(kmf.getKeyManagers(), null, null);
factory = ctx.getSocketFactory();
} catch (Exception e) {
throw new IOException(e.getMessage());
}
SSLSocket socket = (SSLSocket)factory.createSocket("server ip", 9999);
/*
* send http request
*
* See SSLSocketClient.java for more information about why
* there is a forced handshake here when using PrintWriters.
*/
SSLSession session = socket.getSession();
[build query]
byte[] buff = query.toWire();
out.write(buff);
out.flush();
InputStream input = socket.getInputStream();
int readBytes = -1;
int randomLength = 1024;
byte[] buffer = new byte[randomLength];
while((readBytes = input.read(buffer, 0, randomLength)) != -1) {
LOG.debug("Read: " + new String(buffer));
}
input.close();
socket.close();
} catch (Exception e) {
e.printStackTrace();
}
I can write multiple times and I don't get any error but the EOFException happens on the first read.
Am I doing something wrong with the socket or with the SSL authentication?
Thank you.
