Newbie pgp question

Hi guys, I've got a question - may be it is FAQ, the please point me. I need - well, it sounds funny - to crack PGP-encrypted text ;) I have secring.pgp but not the keyphrase - does it make things easier or not? I also have pgpcrack99.zip (DOS-version, zip means that I unzipped it for the 1st time :) But I guess it will take megahours with big dictionary - and it will cover only single words, not sentences. Please, can somebody introduce me a little? TIA PS. I also know few words in that file, may be even phrases. -- ******************************************* Mike Blazer blazer@mail.nevalink.ru *******************************************
