Select the ASN.1 specification (enter manually, upload new, or pick existing). Compile to check the syntax and to extract the data Types to be used in Decoding and Encoding.

Compiling options:

Strict syntax checking Recommended when creating a new standard.

Treat all types as PDUs Allow encoding/decoding for all types, as opposed to PDUs (top-level, unreferenced).

Generate sample valuesGenerate a dummy value for every PDU (a license is required).

Encode
Decode

Enter a Value (in the ASN.1 Value Notation format) for one of the Types defined in the Schema. Click Encode. Various encoded formats will be available as links for downloading.

Encoding options:

Auto Encode open typesPerform automatic encoding of open types (a license is required).

Select the Type. Upload a message/PDU/record file. Click Decode. The decoded data can be downloaded as a text file in the ASN.1 Value Notation format.

Decoding options:

Auto Decode open typesPerform automatic decoding of open types (a license is required).

Decode into CSV formatDecodes multiple concatenated records into a Comma-Separated-Values file (a license is required).

Decode multiple (concatenated) PDUsInput data may contain multiple (concatenated) PDUs, decode all of them (a license is required).

Relay safeDecodes with preserving unknown extensions (a license is required).
