关于ssl：java.security.NoSuchAlgorithmException：X509 KeyManagerFactory不可用

java.security.NoSuchAlgorithmException: X509 KeyManagerFactory not available

我想创建SSL连接。我创建了密钥库。并尝试使用x509。

1	final KeyManagerFactory kmf = KeyManagerFactory.getInstance("X509");

但是运行后我在控制台上遇到异常。

java.security.NoSuchAlgorithmException: X509 KeyManagerFactory not available
at sun.security.jca.GetInstance.getInstance(Unknown Source)
at javax.net.ssl.KeyManagerFactory.getInstance(Unknown Source) SSLContext sc = SSLContext.getInstance(connectionType);
final char[] keyPassPhrase ="changeit".toCharArray();
//String [] array = Security.getProviders();
final KeyStore ks = KeyStore.getInstance("jks");

socket.startHandshake(); //handshake as"SunX509" does not support SSL. I need to create above one. Can someone help. And also with"SunX509" i am getting java.lang.IllegalArgumentException: Cannot support TLS_RSA_WITH_AES_256_CBC_SHA with currently installed providers problem with some ciphers. please help

算法提供者无法识别您正在使用的X509参数。

如getInstance(String algorithm)所述，原因很明显。

NoSuchAlgorithmException - if no Provider supports a KeyManagerFactorySpi implementation for the specified algorithm.

这里描述了标准算法

我猜他们在KeyManagerFactory中支持PKIX, SunX509这两个算法

因此，您必须使用SunX509而不是X509。

见这里的表
