this is my first post so i hope i'm doing this right well, i'm trying to read from a file and encrypt and decrypt it, it seens to encrypt fine but upon decrypting it returns garbled text. i'm useing IO::File to do filehanding and use Crypt::Rijndael_PP ':all' for encryption on win2k pro.
sub encrypt { print "enter key: "; $key=<>; $file->open("+>log.log") or die "$!"; $data = $file; $c_txt = rijndael_encrypt($key, MODE_CBC, $data, 256, 128); $file->print($c_txt);}
lets say i put 'blah' in log.log with a key of 'mo' i get: ð@R`óÎÞèDÓ³83WPõgç×¥^DPÄ“°CCô" which seems fine but when i decrypt it:
sub decrypt { print "enter key: "; $key=<>; $file->open("+>log.log") or die "$!"; $c_txt = $file; $p_txt = rijndael_decrypt($key, MODE_CBC, $c_txt, 256, 128); $file->print($p_txt);}
i get: Ü¥¢Ãs´÷µ|˜+Ûûˆ<g what i'm thinking is that it's the dos line feeds but i don't know how to get rid of them i tried:
$file =~ s/\r$//; and $file =~ s/\n$//;
but that doesn't work, so basically what i'm asking is how to get it to read and write correctly. any ideas? thanks.
