是RC4还是ARCFOUR？ 使用SecretKeySpec时出现InvalidKeyException？

我尝试在我的电脑上运行我的应用程序，但我不断得到这个东西。 我有可能错过一些图书馆吗？ fabsam.crypto.CryptoException: java.security.InvalidKeyException: No installed provider supports this key: javax.crypto.spec.SecretKeySpec at fabsam.crypto.RC4Decoder.decode(RC4Decoder.java:37) ~[bin/:na] … (skipped my projects stack trace) at java.lang.Thread.run(Thread.java:662) [na:1.6.0_25] Caused by: java.security.InvalidKeyException: No installed provider supports this key: javax.crypto.spec.SecretKeySpec at javax.crypto.Cipher.a(DashoA13*..) ~[na:1.6] at javax.crypto.Cipher.init(DashoA13*..) ~[na:1.6] at javax.crypto.Cipher.init(DashoA13*..) ~[na:1.6] at fabsam.crypto.RC4Decoder.decode(RC4Decoder.java:27) ~[bin/:na] … 5 common frames omitted Caused by: java.security.InvalidKeyException: No installed […]

RC4加密java

您好我在尝试用Java实现RC4算法。 我发现这段代码是一个帮助我理解这个想法的例子： public class RC4 { private int[] S = new int[256]; private int[] T = new int[256]; private int keylen; public RC4(byte[] key) throws Exception { if (key.length 256) { throw new Exception(“key must be between 1 and 256 bytes”); } else { keylen = key.length; for (int i = 0; i < 256; […]
