Can anyone provide guidance on building an ASN.1 decoder and encoder
in Python? This does not have to be a general purpose implementation,
drivenf from an ASN.1 template. It can be dedicated hard coded to a
particular template.

I looked at pyasn1. Unfortunately, it is not useful and provides a C
interface. Thanks, anyhow.
I figure that I will have to write my own, but am unsure of the best
approach. Nested lists and distionaries might be useful and I am
looking to the feasibility of those mechanisms.

There might be some useful code in www.trevp.com/tlslite .

What makes you say that? It appears to me (looking at the code in
CVS) to be written entirely in Python, and the home page,
<http://pyasn1.sourcefo rge.net/shows examples clearly with a Python
interface.
I've no idea whether or not it's useful in any other sense.

pyasn1 is a pure-python implementation. C interface is not supported.
I figure that I will have to write my own, but am unsure of the best
approach. Nested lists and distionaries might be useful and I am
looking to the feasibility of those mechanisms.
Try looking at the pyasn1 homepage http://pyasn1.sf.net where some
design ideas were discussed.

Thanks Paul. This is exactly the type andlevel of implementation that
I was looking for.
I will look at the other implementation again.

I'm having trouble understanding the MIME::Decoder usage.
Within the context of a MIME email handling program I have an array, @data,
and I want to uuencode it. I thought I could instantiate a MIME::Decoder
with an encoding of 'x-uuencode' and then call the encode method as,
my $decoder = new MIME::Decoder('x-uuencode');
$decoder->encode(@data, @uudata);
However, the encode method only accepts STREAMs as arguments. Obviously I

Hi,
I needed a basic binary to ascii encoder, so I wrote this piece of
code:
/*
Encoding algo: suppose 11111010 is the byte to be encoded.
It is first broken up into two 4-bit parts (1111 and 1010)
This 4-bit quantity is then padded between a 01 and a 10, ie,
01xxxx10 will be written out to the output file.

Basically my friend's parents used to log his AIM and email so we made a barbaric version of an encoder that we could type in what we wanted and get random letters out. The only problem is that I did it in Truebasic, and I am new to VB. I have the interface layed out with an Encode button and a Decode button with an Input and an output/log. Eventually I want to have it just with universal hotkeys to where you can highlight a text and it...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
