FTP hesla - dekodovani Mam maly problem - ve Far manageru mam definovano asi 20 hesel ale zadny z pluginu ani ostatnich softwaru mi neprecte vsechna hesla. Proste nektere FTP se mi ve vypisech vubec neobjevi (a samotne ftp pripojeni funguje). Poradite nekdo? Nasel jsem jeste toto: Let's assume our password is: abcdef 1. XOR first character 'a' with second character 'b' 2. Perform logical AND operation with the first character and byte 50h: 'a' AND 0x50 (note that 'a' is not anymore 'a' here after the first step) 3. In a loop, starting from the first byte, 'c', we XOR all remaining bytes with the first character. Nevite jestli je to jeste platne nebo se hesla kryptuji jinak? odpovědět

   2. Perform logical AND operation with the first character and byte 50h:
      'a' AND 0x50
      (note that 'a' is not anymore 'a' here after the first step)

Nevite jestli je to jeste platne nebo se hesla kryptuji jinak?

Re: FTP hesla - dekodovani Ja jsem v svn repozitari FTP pluginu nasel nasledujici text: 1.[HKEY_CURRENT_USER\Software\Far\plugins\FTP\ShowPassword] LogType: BOOL RegType: DWORD Name: ShowPassword Default: FALSE Meaning: Do not replace password text with "HIDDEN" a v ftp_Crypt.inc byla funkce: void DecryptPassword( BYTE Src[FTP_PWD_LEN],char _Dest) { BYTE XorMask = (Src[0]^Src[1]) \| 80; int n; char Dest = _Dest; //Log(( "DecryptPassword: %02X %02X %02X %02X %02X %02X",Src[0],Src[1],Src[2],Src[3],Src[4],Src[5] )); if ( Src[0] && Src[1] && Src[2] ) for( n = 2; n < FTP_PWD_LEN; n++,Dest++ ) { Dest = Src[n] ^ XorMask; if ( Dest == 0 \|\| &nb sp; Dest == XorMask ) break; } Dest = 0; //Log(( "DecryptPassword: [%s]",_Dest )); } odpovědět

Re: FTP hesla - dekodovani
Ja jsem v svn repozitari FTP pluginu nasel nasledujici text:

1.[HKEY_CURRENT_USER\Software\Far\plugins\FTP\ShowPassword]
   LogType: BOOL
   RegType: DWORD
      Name: ShowPassword
   Default: FALSE
   Meaning: Do not replace password text with "*HIDDEN*"

a v ftp_Crypt.inc byla funkce:

void DecryptPassword( BYTE Src[FTP_PWD_LEN],char *_Dest)
{ BYTE XorMask = (Src[0]^Src[1]) | 80;
     int n;
     char *Dest = _Dest;

     //Log(( "DecryptPassword: %02X %02X %02X %02X %02X %02X",Src[0],Src[1],Src[2],Src[3],Src[4],Src[5] ));

     if ( Src[0] && Src[1] && Src[2] )
       for( n = 2; n < FTP_PWD_LEN; n++,Dest++ ) {
         *Dest = Src[n] ^ XorMask;
         if ( *Dest == 0 ||
            &nb sp; *Dest == XorMask )
           break;
       }
     *Dest = 0;

     //Log(( "DecryptPassword: [%s]",_Dest ));
}

Re: FTP hesla - dekodovani to vypada zajimave... jen mi to uplne nefunguje - mohl bych poprosit jeste o zdroj pro kryptovaci funkci? slibuji ze pak uz prestanu otravovat :-) odpovědět
