尝试使用 .cer 加密。它在本地系统中工作，但当我转向生产时出现错误。 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;
}
错误堆栈跟踪

最佳答案
java.lang.ClassNotFoundException 当类在您的 classpath 中不可用时生成。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。
java.lang.ClassNotFoundException 没有其他原因
