I'm creating a login back-end, and I need some kind of hashing algorithm for the passwords!
Is md5 or SHA-1 converted to pawn?

[VEN]

/* Calculates the md5 keysum of a string */
native md5(const szString[], md5buffer[34]);
 
/* Calculates the md5 keysum of a file */
native md5_file(const file[], md5buffer[34]);

?

Here's a good hashing algorithm if you need it as an int:

// parameter macros
#define HASH_ALG_PARAMS const str[], len
#define HASH_STR str[]
#define HASH_STR_LEN len

// 'hash' value based macros
#define HASH_VAL hash
#define INITIALIZE_HASH_ALG(%1) new HASH_VAL = %1
#define SET_HASH_VAL(%1) HASH_VAL = (%1)

// loop based macros
#define HASH_LOOP_VAR loop_var
#define HASH_LOOP_CHAR str[HASH_LOOP_VAR]
#define HASH_ALG_LOOP() static HASH_LOOP_VAR; for( HASH_LOOP_VAR = 0; HASH_LOOP_VAR < HASH_STR_LEN ; HASH_LOOP_VAR ++)

// returns a positive value, suitable for a hash algorithm.
#define RETURN_HASHED_VALUE() return ( HASH_VAL & 0x7FFFFFFF)

// Simple and proven algorithms
#define HASHTABLE_SIMPALG_ADD RSHash
#define HASHTABLE_SIMPALG_ROT JSHash

// General purpose algorithms used by reputable companies
// probably for 16-bit; don't work so well on 32-bit
#define HASHTABLE_GENALG_BELL PJWHash
#define HASHTABLE_GENALG_UNIX ELFHash

// Specific purpose algorithms, designed for a certain use.
#define HASHTABLE_SPALG_SEED BKDRHash
#define HASHTABLE_SPALG_SORT DEKHash

// These algorithms do very well in their areas of expertise.
#define HASHTABLE_EXALG_VARIANCE SDBMHash
#define HASHTABLE_EXALG_SPEED DJBHash
#define HASHTABLE_EXALG_RELIABLE APHash

// Simplest addative hashing algorithm
// Speed: 129 || 1288
// Collisions: 2 || 462
// Renders very few collisions, the second lowest, and has a consistant speed of hashing, if a bit higher than normal.
// General purpose
RSHash(HASH_ALG_PARAMS)
{
    INITIALIZE_HASH_ALG(0);

    new b = 378551;
    new a = 63689;

    HASH_ALG_LOOP()    
    {
        SET_HASH_VAL( HASH_VAL * a + HASH_LOOP_CHAR );
        a = a * b;
    }

    RETURN_HASHED_VALUE();
}

That won't be as strong as using md5(), but it'll certainly be faster.

Thanks!
Btw does old amx modules still work on amxx (thinking of the multi threading module)?
