Egy kis elmélet:
''Internal XL passwords are about as useful for security as tissue paper. The reason is that the passwords you enter (i.e., with Tools/Protect/Protect Worksheet or /Protect Workbook) are not used directly in protection. Instead they are hashed (mathematically transformed) into a much less secure code. Effectively, any password of any length is transformed into a string of 12 characters, the first 11 of which have one of only two possible values. The remaining character can have up to 95 possible values, leading to only
2^11 * 95 = 194,560 potential passwords. This may seem like a lot, but it only takes a few seconds for a modern computer to try them all. As a comparison, a 4-character password containing just the 26 lower case alphabet characters has 456,976 combinations, and a 3-character password consisting of lower case, upper case and the digits 0-9 will have 238,328 combinations.''Soha nem késő, hogy azzá válj, aki lehettél volna.
