Does the highlighting library support ASN.1?

Question

On one of my answers, I provided an illustrative ASN.1 specification to accompany it.

However, I could not find the right language to use to make it "light up".

Does StackOverflow or SecuritySE apply any in-house grammars that could be used for this purpose, or is there a grammar ~comparable to ASN.1 in the library somewhere?

There's no way to add color or anything fancy on this website, but you can use some basic markup, even in formatted code, by using <pre> instead of four leading spaces. Note that you may need to use HTML entities for common symbols (such as using > instead of >). Example text showing a simple hello world program in C with the string italicized and all functions made bold:

#include <stdio.h>

int main(void)
{
    printf("Hello, world!\n");
    return 0;
}

This is done by using the following:

<pre>
#include &lt;stdio.h&gt;

int <b>main</b>(void)
{
    <b>printf</b>(<i>"Hello, world!\n"</i>);
    return 0;
}
</pre>

I've used this feature a few times, such as in this answer to provide bold, italics, and superscripts:

5.2    Parsing the message
The message and its padding must be parsed into N m-bit blocks.

5.2.1  SHA-1, SHA-224 and SHA-256
For SHA-1, SHA-224 and SHA-256, the message and its padding are parsed into N
512-bit blocks, M(1), M(2),..., M(N). Since the 512 bits of the input block may be
expressed as sixteen 32-bit words, the first 32 bits of message block i are
denoted M0(i), the next 32 bits are M1(i), and so on up to M15(i).

5.2.2  SHA-334, SHA-512, SHA-512/224 and SHA-512/256
For SHA-384, SHA-512, SHA-512/224 and SHA-512/256, the message and its padding are
parsed into N1024-bit blocks, M(1), M(2),..., M(N). Since the 1024 bits of the input
block may be expressed as sixteen 64-bit words, the first 64 bits of message block
i are denoted M0(i), the next 64 bits are M1(i), and so on up to M15(i).
