For example, in SNMP context, 0xa0 is a PDU_GET object, while in X509 context, it is a container for the certificate version. The article is only about encoding of simple types - REAL, INTEGER, OBJECT IDENTIFIER, all string types, BOOLEAN, NULL, SEQUENCE and SET. IOException Decodes a BIT_STRING value from the given InputStream. org When used with the decode command, if the component corresponding to the optional specifier is not found, the corresponding tcl variable will be unset. DER is a type length value encoding, so the sequence above can be interpreted, with reference to the standard SEQUENCE, INTEGER, and IA5.
