To convert file with decimal to another file with Hexadecimal

I have a text file of alphanumeric values listed one by one. I have to convert them to hexadecimal equivalents for each character seperated by ":" in Unix bash shell script. For example, 12345678 has to be converted to 31:32:33:34:35:36:37:38

what is the logic for the below ?

12345678 has to be converted to 31:32:33:34:35:36:37:38

for 1 the hexadecimal is 1 only.. how come it will come as 31 ?

This should do it..

Code:
 
echo "1234" | perl -F// -lane 'BEGIN{$\=":"} print "", unpack("H*",$_) for @F'


This is the output I've got

Code:
 
31:32:33:34:

Its not an assignment.

I went to the link u suggested above. It talks about ascii chart and extended ascii chart (which i already have), hence not useful for me.

There is another link talks about file. It refers to some order.txt but that order.txt is not available.
