0.1	First public verion. Largely untested except on sample files (Thanks to 	Jim Spring@Netscape).
0.2	Tested files against the newly release MSIE 4. Added local key id so it
	would import them. Fixed bugs that didn't print out keybags.
0.3	Since it was tricky to apply the patch it was changed to a set of 
	replacement files. Added lots of options to pkcs12 program, including
	iteration count options and allowing ciphers to be set. Also additional
	files to allow painless compilation under WIN32.
0.4	Major rewrite to allow it to be used as an external program/library
	with SSLeay 0.9.0. Now uses dynamic objects. Added support for DSA keys.
0.41	Fixed a bug that caused generated output files to be bad (missing 
	p12_nid).
0.50	Plugged lots of memory leaks: thanks to Markus Isler
	(markus@hardcastle.co.nz) for pointing out how badly it leaked. Rewrite
	of PBE system to support dynamic ciphers. Workaround for nasty object
	creation bug in SSLeay 0.9.0 (this only really hits when you actually
	start freeing things!). Allowed use of ASCII as compile time option
	instead of steenking Unicode. Added support for some broken key formats
	and added some useful macros for reading and writing PKCS#12 files. 
	Fixed broken macros that were using "bag" twice.
0.51	Fixed improper use of memset calls and added a WIN32 makefile.
0.51a	Used the proper WIN32 Makefile this time.
0.52	Added support for MS key usage attributes, got rid of p12_nid.
	Also "make errors" now works under WIN32.
0.53a	Added NO_IDEA define to pkcs12.c. DEBUG_DECRYPT flag to dump
	decrypted output to files. Made pkcs12.c a bit cleverer at working out
	which key belongs to which cert. Support for ranlib in Makefile. Changed
	prototype for PKCS8_add_key_usage (it chokes some compilers). Also
	made the attributes use an empty SET which should keep broken MSIE
	PKCS#12 happy even when no bag attributes are present: thanks to Srin
	Kumar (SrinK@interdyn.com) for suggesting this. pkcs12.c now prints out
	all attributes and does something useful even if it doesn't recognise 
	them. Added support for OpenSSL.
0.53b	Add various #define and #ifdefs so it should now compile under
	SSLeay 0.9.x, OpenSSL 0.9.1c and OpenSSL 0.9.2.
0.54	New function PKCS12_parse(): this was originally written for Celo
	Communications AB (http://www.celocom.com) who have kindly allowed me
	to include in in the main distribution. New function PKCS12_create()
	which can create a PKCS#12 structure with one call. Fix a compatability
	bug which messed up the ASN1 encoding of -keysig and -keyex. Add a
	version checker to ensure it is running under the version of OpenSSL or
	SSLeay it thinks it is. Changed the {i2d,d2i)_PKCS12_{bio,fp} macros
	into functions. This seems to be the only way to keep all the C++
	compilers quiet.
