java实现的RC4加密解密算法示例

 public static String HloveyRC4(String aInput,String aKey) { int[] iS = new int[256]; byte[] iK = new byte[256]; for (int i=0;i<256;i++) iS[i]=i; int j = 1; for (short i= 0;i<256;i++) { iK[i]=(byte)aKey.charAt((i % aKey.length())); } j=0; for (int i=0;i<255;i++) { j=(j+iS[i]+iK[i]) % 256; int temp = iS[i]; iS[i]=iS[j]; iS[j]=temp; } int i=0; j=0; char[] iInputChar = aInput.toCharArray(); char[] iOutputChar = new char[iInputChar.length]; for(short x = 0;x

 public static void main(String[] args) { String inputStr = "做个好男人"; String key = "abcdefg"; String str = HloveyRC4(inputStr,key); //打印加密后的字符串 System.out.println(str); //打印解密后的字符串 System.out.println(HloveyRC4(str,key)); }
