If you are using Linux/Mac go to a command prompt and enter
so something like base64 -d <filename> or echo "base64texthere" | base64 -d
should work
you've already got a base64 encoder/decoder built in. If it's actually encrypted you'll need a decryption key and run it through openssl and is outside the scope of this answer.
Ez all!
I have a question how to decrypt text uses letter frequency analysis. I have code which count the letters, but what i need to do after that. Can anybody help me to write a code. VERY NEEDED! My code now:

I'm trying to replace the string %2d from a text file using sed, and I can't seem to find the right key combination. I've tried:
sed 's/%2d/-/' foo
The above doesn't work, presumably because of the %. :mad: Interestingly, I don't get any kind of error message at all. It appears to... (5 Replies)
Dear Friends,
I have an XML file that's encoded in ISO-8859-1. I have some European characters coming in from 2 fields (Name, Comments) in the XML file. Can anyone suggest if there are any functions in Unix to read those characters? Using shell programming, can I parse this xml file?
Please... (0 Replies)
Hi,
I have a non-ascii character (Ŵ), which can be represented in UTF-8 encoding as equivalent hex value (\xC5B4). Is there a function in unix to convert this hex value back to display the charcter ? (10 Replies)
Hi,
I have a couple pages of URL encoded strings that I need to unencode (they were originally in Arabic). So the first step is to unencode the strings and then to translate them to English. They are actually lists of words so the translation from Arabic to English shouldn't be too complicated.... (1 Reply)

base64
base64(n) Text encoding & decoding binary data base64(n)
__________________________________________________________________________________________________________________________________________________NAME
base64 - base64-encode/decode binary data
SYNOPSIS
package require Tcl 8
package require base64 ?2.4.2?
::base64::encode ?-maxlen maxlen? ?-wrapchar wrapchar? string
::base64::decode string
_________________________________________________________________DESCRIPTION
This package provides procedures to encode binary data into base64 and back.
::base64::encode ?-maxlen maxlen? ?-wrapchar wrapchar? string
Base64 encodes the given binary string and returns the encoded result. Inserts the character wrapchar every maxlen characters of
output. wrapchar defaults to newline. maxlen defaults to 76.
Note well: If your string is not simple ascii you should fix the string encoding before doing base64 encoding. See the examples.
The command will throw an error for negative values of maxlen, or if maxlen is not an integer number.
::base64::decode string
Base64 decodes the given string and returns the binary data. The decoder ignores whitespace in the string.
EXAMPLES
% base64::encode "Hello, world"
SGVsbG8sIHdvcmxk
% base64::encode [string repeat xyz 20]
eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6
eHl6eHl6eHl6
% base64::encode -wrapchar "" [string repeat xyz 20]
eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6
# NOTE: base64 encodes BINARY strings.
