First of all thank you very much for the critique,it is very well welcomed from my part.
I will use it to improve the program.
1)why do you think the current method of opening the files does not yield correct results ?
(I compared my results of SHA1s against sha1sum unix utilitary and they came out ok,that's
why I'm asking).
2)you are right,I will do this
3)ok I understand,where could I read more about this ?
4)As I read the documentation and thinking that a number in base 10 should always present more
digits than its representation in base 16 I dont understand how it could be shorter in base 10.
I don't get why they say I will get a shorter string in a lower base.


Also they talk about using a single sha1 object and reusing it because of the reset() method that
can clear out the old data from it.
Do you think this will speed up things ?

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
