org.bouncycastle.jcajce.provider.asymmetric.rsa.CipherSpi$NoPadding :java.lang.ClassNotFoundException

Question

正在尝试使用.cer进行加密。它在本地系统中工作，但在我转移到生产环境时出现错误。我在Live服务器上有bcprov-jdk15on-158.jar文件。

源代码

public static byte[] encryptUsingPublicKey(byte[] data, PublicKey publicKey) throws IOException, GeneralSecurityException {
    Cipher pkCipher = Cipher.getInstance("RSA/ECB/PKCS1Padding", "BC");//Here iam Getting Error
    pkCipher.init(Cipher.ENCRYPT_MODE, publicKey);
    byte[] encSessionKey = pkCipher.doFinal(data);
    return encSessionKey;
}

当类在classpath中不可用时生成的java.lang.ClassNotFoundException。检查您的classpath是否包含预期的jar。即使它在服务器上，但可能不包含在classpth中。

没有其他原因导致java.lang.ClassNotFoundException
