Hash API is defined in  GSCryptBase.h (see GSHashObject class)

        example:
          NSString* hashedPassword=nil;
          NSData* md5Sum=nil;
          md5Sum=[GSMD5 digestOfString:password
                        usingEncoding:NSASCIIStringEncoding];
          hashedPassword=DataToHexString(md5Sum);

RC4 example: 
        GSRC4* myRC4=[GSRC4 rc4WithKey:myKey]; // myKey is a NSData
        NSData* encrypteddata=[myRC4 crypt:myData]; //myData is a NSData

        ti decrypt:
        GSRC4* myRC4=[GSRC4 rc4WithKey:myKey]; // myKey is a NSData
        NSData* data=[myRC4 decrypt:encryptedData]; //encryptedData is a NSData
