How is a CRC32 checksum calculated?
...e CRC-32 as a series of "Binary Arithmetic with No Carries", or basically "XOR and shift operations". This is technically called Polynomial Arithmetic.
CRC primer, Chapter 5
To better understand it, think of this multiplication:
(x^3 + x^2 + x^0)(x^3 + x^1 + x^0)
= (x^6 + x^4 + x^3
+ x^5 + x^3...
How to encrypt String in Java
...[] ivBytes;
Now you can initialize the Cipher for the algorithm that you select:
// wrap key data in Key/IV specs to pass to cipher
SecretKeySpec key = new SecretKeySpec(keyBytes, "DES");
IvParameterSpec ivSpec = new IvParameterSpec(ivBytes);
// create the cipher with the algorithm you choose
// ...
techniques for obscuring sensitive strings in C++
...e sure that the key is not within the printable range.
Obscuring key with XOR
For instance, you could use XOR to split the key into two byte arrays:
key = key1 XOR key2
If you create key1 with the same byte-length as key you can use (completely) random byte values and then compute key2:
key1[n...
