DER ASCII is a small human-editable language to emit DER (Distinguished
|
||
|
|
Encoding Rules) or BER (Basic Encoding Rules) encodings of ASN.1 structures
|
||
|
|
and malformed variants of them.
|
||
|
|
|
||
|
|
The package provides two tools, ascii2der and der2ascii, to convert DER
|
||
|
|
ASCII to a byte string and vice versa. These tools may be used to create
|
||
|
|
test inputs by taking an existing DER or BER structure, disassembling it
|
||
|
|
with der2ascii into DER ASCII, making adjustments, and assembling back into
|
||
|
|
binary with ascii2der. This avoids having to manually fix up all the length
|
||
|
|
prefixes. As a bonus, it acts as a human-readable view for DER structures.
