About Parse ASN.1 hex string
Abstract Syntax Notation One (ASN.1) is a standard and notation that describes rules and structures for representing, encoding, transmitting, and decoding data in telecommunications and computer networking. This operation parses arbitrary ASN.1 data (encoded as an hex string: use the 'To Hex' operation if necessary) and presents the resulting tree.
Input: text. Output: text.
Format reference: Parse ASN.1 hex string background and specification
Example
Use “Try example” to load this public sample and its settings, then run it.
Settings used in this example
| Parameter | Example value | Input and choices |
|---|---|---|
| Starting index | 0 | Number |
| Truncate octet strings longer than | 32 | Number |
Input
3006020101020102
Result
The example demonstrates the configured operation. Generated values, timestamps or formatting may vary between runs.
Parameters
| Parameter | Default value | Input and choices |
|---|---|---|
| Starting index | 0 | Number |
| Truncate octet strings longer than | 32 | Number |
Before interpreting the result
Choose a decoder for an encoded payload, an encoder for transport, or a converter for structured data. Hex and Base64 represent bytes; converting formats does not encrypt or authenticate them.
How to use this page
- Paste your input or open a local file.
- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
