BouncyCastleProvider do not get PrivateKey and certificate chain from PKCS#12 file

Question

I have file cert.pfx exported on Windows. This file contains my certificate. On Ubuntu i can open it with password and I see the certificate. But when I loaded this file:

BouncyCastleProvider provider = new BouncyCastleProvider();
Security.addProvider(provider);
KeyStore ks = ks = KeyStore.getInstance("pkcs12", provider.getName());
ks.load(new FileInputStream("/home/test/.cert.pfx", "xxxxxx".toCharArray());
String alias = ks.aliases().nextElement();
PrivateKey pk = (PrivateKey) ks.getKey(alias, pts.getRandom());
Certificate[] chain = ks.getCertificateChain(alias);

After this operations I have null in pk and chain.
Also I have registered BC provider in java.security

Answer 1

I changed BouncyCastleProvider to SunJSSE. Now my correctly code is:

String providerName = "SunJSSE";
KeyStore ks = ks = KeyStore.getInstance("pkcs12", providerName);
ks.load(new FileInputStream("/home/test/.cert.pfx", "xxxxxx".toCharArray());
String alias = ks.aliases().nextElement();
PrivateKey pk = (PrivateKey) ks.getKey(alias, pts.getRandom());
Certificate[] chain = ks.getCertificateChain(alias);

Now in pk is my privarte key, and in chain is certificate chain.
I don't know why in BC doesn't work. I have other certificate and BC provider work correctly.
