SSL サーバーに対して単純な要求を行い、応答を待機する SSL クライアントを開発しています。SSL ハンドシェイクと書き込みは正常に行われますが、ソケットからデータを読み取ることができません。java.net.ssl のデバッグをオンにすると、次のようになりました。
[..]
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
[..]

[..] は証明書チェーンです。
コード スニペットを次に示します。
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();
}
複数回書き込むことができ、エラーは発生しませんが、最初の読み取りで EOFException が発生します。
ソケットまたは SSL 認証に問題がありますか?
ありがとうございました。
