Talk:ASN.1

message: Why the capital letters in the article's title while lower-case is used in the first sentence?  Which is correct?  (Wikipedia articles conventionally do not capitalize words in article titles unless they would otherwise be capitalized, except that the first letter is case-insensitive and always gets rendered as a capital.)

thread_title: Captial letters

message: This recently added section is problematic as there are multiple ASN.1 encoding rules which produce textual output, such as GSER.   Additionally one doesn't need a compiler to produce encoders/decoders for binary encodings, and one may use a compiler to produce encoders/decovers for textual encodings.  I recommend this section be deleted or significantly rewritten.  Kdz 20:57, 25 February 2006 (UTC)
replies: text: Agreed. GSER is not a good example as it's primarily meant merely for inputting/representing data by/for the user, but XER entirely qualifies as a textual representation of ASN.1. -- intgr 22:01, 25 February 2006 (UTC)

:Note that all values are in hexadecimal, so we have: 1 (length of integer tag) + 1 (length of integer length) + 1 (length of integer value) + 1 (length of string tag) + 1 (length of string length) + 0e (length of string value) = 13. Rasmus (talk) 20:06, 18 June 2006 (UTC)
thread_title:  A small error in DER encoding example? 

message: Or Keep It Simple, Stupid! Example section is meant for people who completely don't understand what ASN.1 is about. And not for people who want to learn how unaligned PER is "better" than XER.  I've noticed a trend to overly complicate this section.
So be gentle and don't throw all information at once. Step by step, step by step. Simple language. One new term per paragraph :)

thread_title:  Yes! 

message: The text says "122 bits (less than 16 octets)" then shows 16 hexadecimal pairs which would be 16 full octets or 128 bits.  There is an example at the end showing 17 octets, but none has the highest bit set.  If these are septets, that's 119 bits.  I notice that the first three pairs don't change between the two examples, so if I read the second example as three octets followed by 14 septets that makes 122, but the text should lead me to a 122 bit explanation.    Randall Bart    Talk   17:53, 12 January 2013 (UTC)

message: I have compiled a (non-exhaustive) list of open-source ASN.1 implementations and their features: https://github.com/alexvoronov/geonetworking/tree/master/asn1-datatypes#other-asn1-tools.

message: The provided example for encoding using unalligned PER is:
01 05 0e 83 bb ce 2d f9 3c a0 e9 a3 2f 2c af c0
There are 13 (0x0d) octets describing the string, however the described length is 14 (0x0e). Is this correct? Is the length in terms of 7 bit characters (as in the example), or in 8 bit octets (as described earlier in the text)?
I think the example should get an additional note explaining this. I cannot add it myself, since I do not know the answer.  — Preceding unsigned comment added by 85.149.106.126 (talk) 15:08, 14 December 2020 (UTC)
