RSA Encryption
Here is my goal:1. Take a string2. Encrypt it 3. Pass it as a parameter in the QueryString4. Decrypt it The value starts as a string, then is converted to a byte[] and then encrypted.  The resulting byte[] is converted to a string and send as a parameter.  The recieving page decrypts the string (creates a byte[], decrypts to a new byte[], and the value is finally parsed for its values) I am using http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemsecuritycryptographyrsacryptoserviceproviderclasstopic.asp with a small modification t...

Am I correct in thinking that the only way to get ord() to return a value over 256 is to send the character as a Unicode string instead of a byte string?
In other words, is there any character that will make ord() return over = 256 when passed in as a byte string? For example, note the differences in output between a unicode string and = a byte string regarding character 257, as a unicode string it is 257, as = a byte string it is 196. $ perl -C6 -le 'print "Character 257 info:";print "\tunicode \\x{} = notation: " . sprintf(q{\x{%x}}, 257);print "\tOutput as Unicode string = \x{101}";print "\tunicode string \\x{} notation ord(): " . = ord("\x{101}");print "\tbyte string gr...

To Encode String or to Not Encode String... Answer?
I am importing a CSV file from a Unix server as a string, and then saving the string into a new file for later processing.  However, this process does not always work.  As this CSV file is VERY, VERY large, I am unable to immediately tell if the fault lies with my code, or the CSV file provider (very possible).  The only time I can tell that this happened is when the data is not populated the next morning.  The fault appears to lie in there being extra or missing commas, as when I try to run the data import manually, STRINGs are attempted to be inserted into INT...

How do I convert string to a byte array?
[see also http://forums.sybase.com/cgi-bin/webnews.cgi?cmd=item-232695&group=sybase.public.powerbuilder.general] Working with an old OLE object for TCP comm, and the unicode vs ANSI charset change at PB 10 seems to be causing issues. BUT! the old object avoids "'wide' to ANSI" conversion and just sends what it's handed if it's handed a BYTE Array. However, getting there from a string seems to involve conversion to and parsing from a Blob, something that I'm fumbling. Some help on this conversion process would be appreciated.
