* new database per call if the caller wants to get meaningful information
|
|
* about the new database.
|
|
*
|
|
* moduleSpec is the same data that you would pass to softoken at
|
|
* initialization time under the 'tokens' options. For example, if you were
|
|
* to specify tokens=<0x4=[configdir='./mybackup' tokenDescription='Backup']>
|
|
* You would specify "configdir='./mybackup' tokenDescription='Backup'" as your
|
|
* module spec here. The slot ID will be calculated for you by
|
|
* SECMOD_OpenUserDB().
|
|
*
|
|
* Typical parameters here are configdir, tokenDescription and flags.
|
|
*
|
|
* a Full list is below:
|
|
*
|
|
*
|
|
* configDir - The location of the databases for this token. If configDir is
|
|
* not specified, and noCertDB and noKeyDB is not specified, the load
|
|
* will fail.
|
|
* certPrefix - Cert prefix for this token.
|
|
* keyPrefix - Prefix for the key database for this token. (if not specified,
|
|
* certPrefix will be used).
|
|
* tokenDescription - The label value for this token returned in the
|
|
* CK_TOKEN_INFO structure with an internationalize string (UTF8).
|
|
* This value will be truncated at 32 bytes (no NULL, partial UTF8
|
|
* characters dropped). You should specify a user friendly name here
|
|
* as this is the value the token will be refered to in most
|
|
* application UI's. You should make sure tokenDescription is unique.
|
|
* slotDescription - The slotDescription value for this token returned
|
|
* in the CK_SLOT_INFO structure with an internationalize string
|
|
* (UTF8). This value will be truncated at 64 bytes (no NULL, partial
|
|
* UTF8 characters dropped). This name will not change after the
|
|
* database is closed. It should have some number to make this unique.
|
|
* minPWLen - minimum password length for this token.
|
|
* flags - comma separated list of flag values, parsed case-insensitive.
|
|
* Valid flags are:
|
|
* readOnly - Databases should be opened read only.
|
|
* noCertDB - Don't try to open a certificate database.
|
|
* noKeyDB - Don't try to open a key database.
|
|
* forceOpen - Don't fail to initialize the token if the
|
|
* databases could not be opened.
|
|
* passwordRequired - zero length passwords are not acceptable
|
|
* (valid only if there is a keyDB).
|
|
* optimizeSpace - allocate smaller hash tables and lock tables.
|
|
* When this flag is not specified, Softoken will allocate
|
|
* large tables to prevent lock contention.
