\subsection{ASN.1 Flexi Decoder}
The ASN.1 \textit{flexi} decoder allows the developer to decode arbitrary ASN.1 DER packets (provided they use data types LibTomCrypt supports) without first knowing
the structure of the data. Where der\_decode \_sequence() requires the developer to specify the data types to decode in advance the flexi decoder is entirely

The flexi decoder uses the same \textit{ltc\_asn1\_list} but instead of being stored in an array it uses the linked list pointers \textit{prev}, \textit{next}, \textit{parent}
