WebFeb 13, 2013 · The instruction MOV CL,BYTE PTR DS: [EDI+4021A3] picks up one character, starting at 004021A3 from Hex dump and moving to CL (‘M’). The instruction MOV BL,BYTE PTR DS: [ESI] transfers one byte to BL (our password’s first letter ‘N’). XOR BL,CL does an XOR operation with ‘M’ and ‘N’. WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
