ASN2CSV Change Log

ASN2CSV 2.2.4 – Released 2 March 2012

Changes introduced between versions 2.2.4 and 2.1.3 include the following:

• Updated version number to be consistent with ASN1VE.
• ASN2CSV now quotes all fields as strings by default to avoid improper interpretation by common editors like Excel or OpenOffice.org Calc. Use –noquotes to disable this behavior.
• ASN2CSV no longer pads fields with redundant data; this saves a considerable amount of space in the output files. Use –-padFields to duplicate these fields.
• Logic for handling SEQUENCE OF and CHOICE items has been improved, resulting in cleaner output.
• Added an error handler that prints bad records to a file if possible (ASNVE-842).
• Fixed a logic error that caused all TBCD strings to be treated as BCD strings instead (ASNVE-657).
• Improved logic for decoding elements in a list, improving performance in some cases (notably TAP3) by an order of magnitude (ASNVE-613).

ASN2CSV 2.1.3 – Released 7 February 2011

Changes introduced between version 2.1.3 and 2.1.2 include the following:

• Added the –headerOffset command-line option to allow users to skip the first n bytes of a message. This was introduced to make it easier to read CDRs with prefixed headers.

ASN2CSV 2.1.2 – Released 5 November 2010

Changes introduced between version 2.1.2 and 2.1.1 include the following:

• Added the –bcdhandling command-line option to allow users to control the way that BCD encoding and decoding are done. This aligns ASN2CSV with ASN2XML and ASN1VE (ASNVE-541).
• Introduced the –I command-line option to allow users to import ASN.1 specifications from other directories (ASNVE-517).
• Introduced the –skip command-line option to allow decoding of IETF-formatted BER data files (ASNVE-497).
• Fixed a problem that was causing decoded CHOICE types to be inserted into the wrong CSV file.

ASN2CSV 2.1.1 - Released 16 September 2010

Changes introduced between version 2.1.1 and version 2.1.0 include the following:

• Fixed a problem that caused names with dashes to be improperly resolved by the ASN.1 parser (ASNVE-463).
• Updated naming rules for deeply nested CHOICE types (ASNVE-463).

ASN2CSV 2.1.0 - Released 30 July 2010

This is the initial release of ASN2CSV 2.1. This version incorporates the following changes from ASN1VE and ASN2XML:

• Changed the behavior of ASN2CSV's BCD string handling (ASNVE-397):
  • BCDString is now a recognized type.
  • The -bcd command-line switch forces all OCTET STRINGs to be treated as BCD strings. Byte order is right-to-left; values greater than 9 are considered terminating digits.
  • The -tbcd command-line switch forces all OCTET STRINGs to be treated as TBCD strings. Byte order is swapped (left-to-right); the 0xf byte is considered a terminating digit.
  • The -nobcd command-line switch forces all OCTET STRINGs to be literally rendered with no interpretation.
