libtasn1 3.0

Item posted by Nikos Mavrogiannopoulos <nmav> on Mon 29 Oct 2012 06:48:26 PM UTC.

GNU Libtasn1 is a standalone library written in C for manipulating ASN.1 objects including DER/BER encoding/decoding.  GNU Libtasn1 is used by GnuTLS to handle X.509 structures and by GNU Shishi to handle Kerberos V5 structures.

This release includes several optimizations which provide a significant performance boost in the library.

  • Noteworthy changes in release 3.0 (2012-10-28) [stable]

- Added tool in tests/ to benchmark X.509 structure decoding.
- Added asn1_read_node_value() to obtain a node's value.
- Optimizations in internal tree allocation.
- Optimizations in tree search.
- libtasn1.h no longer exports internal structures.
- Types were renamed for consistency:
  ASN1_DATA_NODE -> asn1_data_node_st
  ASN1_ARRAY_TYPE -> asn1_static_node
  ASN1_TYPE -> asn1_node
  static_struct_asn -> asn1_static_node_st
  node_asn_struct -> asn1_node_st
  node_asn -> asn1_node_st
  (the old types are still available as definitions)
