RC4 is pretty good too. This function will do it for you:
void RC4(Char* sIn, UInt32 iInLen, Char* sKey, UInt32 iKeyLen) {
UInt8* inp = (UInt8*)sIn;
UInt8* key = (UInt8*)sKey;
UInt8 s[256];
UInt8 k[256];
UInt32 i;
UInt32 j;
UInt8 temp;
UInt32 t;
UInt32 x;
for (i = 0; i < 256; i++) {
s[i] = (UInt8) i;
}
j = 0;
for (i = 0; i < 256; i++) {
k[i] = key[j++];
j %= iKeyLen;
}
j = 0;
for (i = 0; i < 256; i++) {
j = (j + s[i] + k[i]) % 256;
temp = s[i];
s[i] = s[j];
s[j] = temp;
}
i = 0;
j = 0;
for (x = 0; x < iInLen; x++) {
i = (i + 1) % 256;
j = (j + s[i]) % 256;
temp = s[i];
s[i] = s[j];
s[j] = temp;
t = (s[i] + s[j]) % 256;
inp[x] ^= s[t];
}
}
