/* The format used to protect the private key components is a standard
   cryptlib envelope, however for various reasons the required enveloping
   functionality (which in practice is just minimal code to process a
   PasswordRecipientInfo at the start of the data) is duplicated here
   because:

	1. It's somewhat inelegant to use the heavyweight enveloping routines to
	   wrap up 100 bytes of data.

	2. The enveloping code is enormous and complex, especially when extra
	   sections like zlib and PGP and S/MIME support are factored in.  This
	   makes it difficult to compile a stripped-down version of cryptlib,
	   since private key storage will require all of the enveloping code to 
	   be included.

	3. Since the enveloping code is general-purpose, it doesn't allow very
	   precise control over the data being processed.  Specifically, it's
	   necessary to write the private key components to a buffer in plaintext
	   form, which isn't permitted by the cryptlib kernel.

   For these reasons the PKCS #15 modules include the code to process minimal
   (password-encrypted data) envelopes */

/* Alongside per-key protection, PKCS #15 also allows for an entire keyset 
   to be integrity-protected, but the key management makes this more or less 
   impossible to deploy using a general-purpose API.  If only a single key 
   is present in the file then it's partly feasible, except that once a 
   keyset is cast in stone no further updates can be made without requiring 
   passwords at odd times.  For example a certificate update would require a 
   (private-key) password in order to recalculate the integrity-check value 
   once the certificate has been added.  In addition the password would need 
   to be supplied at file open, when the whole file is parsed, and then 
   again when the private key is read, which leads to a rather puzzling API 
   for anyone not in the know.

   In the presence of multiple keys this becomes even more awkward since the 
   per-key password isn't necessarily the same as the per-file password, so 
   you'd need to provide a password to open the file and then possibly 
   another one to get the key, unless it was the same as the per-file 
   password.  If there was one per-file password and multiple per-key 
   passwords then you would't know which key or keys used the per-file 
   password unless you opportunistically tried on each per-key access, and 
   the chances of that successfully making it up into any UI that people 
   create seem slim.  In addition updates are even more problematic than for 
   the one file, one key case because whoever last added a key would end up 
   with their per-key password authenticating the whole file */
