JAVA 算法逆向。。是哪种算法 逆向。。怎么操作

Question

byte[] arrayOfByte4 = { 0, 65, 0, 3, 0, -113, -115, -38, -106, -26, -14, -81, 3, -112, -94, -22, 89, 37, 77, -6, 39, -29, 67, -82, -44, -103, 47, 21, 38, 71, -89, 72, 2, 89, -49, -19, 1, 110, 74, 68, -117, -28, 123, 107, 107, 92, 105, -5, 59, -23, 11, -107, -27, 36, -85, -22, 101, 82, -40, -108, 15, -103, 61, -39, 52, 28, 57, -28, 101, 1, 0, 1 };
int i3 = (arrayOfByte4[0] & 0xFF) << 8 | arrayOfByte4[1] & 0xFF;
int i4 = (arrayOfByte4[2] & 0xFF) << 8 | arrayOfByte4[3] & 0xFF;
byte[] arrayOfByte6 = new byte[i3];
byte[] arrayOfByte7 = new byte[i4];
System.arraycopy(arrayOfByte4, 4, arrayOfByte6, 0, i3);
System.arraycopy(arrayOfByte4, 4 + i3, arrayOfByte7, 0, i4);
Object localObject5 = new BigInteger(1, arrayOfByte6);
Object localObject6 = new BigInteger(1, arrayOfByte7);
int i6 = (((BigInteger)localObject5).bitLength() + 7) / 8;
int i7 = i6;
int i8 = i6 - 1;
int i9 = (arrayOfByte3.length + i7 - 1) / i7 * i8;
byte[] arrayOfByte5 = new byte[i9];
int i10 = 0;
int i11 = 0;
