Free Online ASN.1 Messages Decoder

This online decoder allows decoding of ASN.1 encoded messages (PDU) which are not part of LTE, UMTS, automotive, ... domains. No ASN.1 syntaxes are required. Simply choose the ASN.1 interface you want to use and supply the data.
Available ASN.1 syntaxes are 3GPP MAP, 3GPP RRLP and Performance Measurement, ITU-T H.245 and T.38.
For other application domains please use another decoder on the right.

Supported ASN.1 encoded inputs are raw (binary) or hexadecimal format. The generated output is in XML format.
