- * Initialize the local recording of the user S/MIME cipher preferences.
- * This function is called once for each cipher, the order being
- * important (first call records greatest preference, and so on).
- * When finished, it is called with a "which" of CIPHER_FAMILID_MASK.
- * If the function is called again after that, it is assumed that
- * the preferences are being reset, and the old preferences are
- * discarded.
- *
- * XXX This is for a particular user, and right now the storage is
- * XXX local, static.  The preference should be stored elsewhere to allow
- * XXX for multiple uses of one library?  How does SSL handle this;
- * XXX it has something similar?
- *
- *  - The "which" values are defined in ciferfam.h (the SMIME_* values,
- *    for example SMIME_DES_CBC_56).
- *  - If "on" is non-zero then the named cipher is enabled, otherwise
- *    it is disabled.  (It is not necessary to call the function for
- *    ciphers that are disabled, however, as that is the default.)
- *
- * If the cipher preference is successfully recorded, SECSuccess
- * is returned.  Otherwise SECFailure is returned.  The only errors
- * are due to failure allocating memory or bad parameters/calls:
- *      SEC_ERROR_XXX ("which" is not in the S/MIME cipher family)
- *      SEC_ERROR_XXX (function is being called more times than there
