|
|
:: | |_newcerts -> priecinok s podpisanymi certifikatmi, ich nazov sa rovna ich seriovemu cislu
|

|
|
:: | |_private -> priecinok pre privatne kluce (mal by mat obmedzeny pristup)
|

|
|
:: | |_index/index.txt -> databaza podpisanych certifikatov, ktora obsahuje detaily o podpisanych certifikatoch
|

|
:: | |_serial -> pocitadlo podpisanych certifikatov
|

|
|
:: | |_crlnumber -> pocitadlo zneplatnenych certifikatov
|

:: kazdy certifikat je mozne identifikovat pomocou serioveho cisla - zaznam sa nachadza v subore index.txt

:: zneplatnenie moze nastat ak doslo k prezradeniu privatneho kluca, ide o podvodny certifikat alebo sa zmenili informacie ziadatela certifikatu
|

|
:: @ index.txt - subory pouzity ako databaza vsetkych podpisanych certifikatov
