Porting C code
HI Guys,
I need help on porting this code to java:
int mysql_encodePassword(char *szOut,char *szPassword,char *szSalt )
{
auto unsignedlong ulP1;
auto unsignedlong ulP2;
auto unsignedlong ulS1;
auto unsignedlong ulS2;
auto unsignedlong ulSeed1;
auto unsignedlong ulSeed2;
autoint i;
autodouble f;
autochar cExtra;
mysql_hash_password( szPassword, &ulP1, &ulP2 );
mysql_hash_password( szSalt, &ulS1, &ulS2 );
ulSeed1 = (ulP1 ^ ulS1) % 0x3FFFFFFF;
ulSeed2 = (ulP2 ^ ulS2) % 0x3FFFFFFF;
for( i=0; i<strlen(szSalt); i++ )
{
f = mysql_rand( &ulSeed1, &ulSeed2);
szOut[i] = (char)( floor(f * 31) + 64 );
}
f = mysql_rand( &ulSeed1, &ulSeed2 );
cExtra = (char)floor(f * 31);
for( i=0; i><strlen(szSalt); i++ )
{
szOut[i] = szOut[i] ^ cExtra;
}
szOut[i] ='\0';
return strlen(szOut);
}
///////////////////////////////////////
void mysql_hash_password(char *szPassword, unsignedlong *pulN1, unsignedlong *pulN2 )
{
auto unsignedlong ulN1;
auto unsignedlong ulN2;
autoint iAdd;
autochar *pIn;
auto unsignedchar c;
ulN1 = 1345345333;
ulN2 = 0x12345671;
iAdd = 7;
for( pIn=szPassword; *pIn; pIn++ )
{
c = *pIn;
if( (c ==' ') || (c =='\t') )
continue;
ulN1 = ulN1 ^ ( ( ( ulN1 & 63 ) + iAdd ) * c + (ulN1 ><< 8) );
ulN2 = ulN2 + ((ulN2 << 8) ^ ulN1);
iAdd = iAdd + c;
}
*pulN1 = ulN1 & 0x7FFFFFFF;
*pulN2 = ulN2 & 0x7FFFFFFF;
}
///////////////////////////////////////
double mysql_rand(unsignedlong *pulSeed1, unsignedlong *pulSeed2)
{

ulSeed1 = *pulSeed1;
ulSeed2 = *pulSeed2;
ulSeed1 = ( ( ulSeed1 * 3 ) + ulSeed2 ) % MYSQL_RAND_MAGIC;

*pulSeed1 = ulSeed1;
*pulSeed2 = ulSeed2;
return ((double)ulSeed1) / ((double)MYSQL_RAND_MAGIC);
}
and this is what I've done so far:
privatebyte[] encryptPassword(byte[] pPassword,byte[] pSalt)
{
long[] hashPassword;
long[] hashSalt =newlong[2];
int hashKeyTmp = 0;
String hashKey =new String();
double f;
char cExtra;
int index;
hashPassword = mysqlHashPassword(pPassword);
hashSalt = mysqlHashPassword(pSalt);
hashPassword[0] = (hashPassword[0] ^ hashSalt[0]) % 0x3FFFFFFF;
hashPassword[1] = (hashPassword[1] ^ hashSalt[1]) % 0x3FFFFFFF;
for(index=0; index < pSalt.length; index++ )
{
f = mysqlRand(hashPassword[0], hashPassword[1]);
hashKeyTmp = (char)(Math.floor(f * 31) + 64 );
hashKey += hashKeyTmp;
}
f = mysqlRand(hashPassword[0], hashPassword[1] );
cExtra = (char)Math.floor(f * 31);
for(index = 0; index < pSalt.length; index++ )
{
hashKeyTmp = (hashKeyTmp ^ cExtra);
hashKey += hashKeyTmp;
}
hashKey +='\0';
return hashKey.getBytes();
}

hashedString[1] = 0x12345671;

Unfortunately it is not working properly... I am still debugging but I was never a true C developer....
Any help is welcome,
