- * This is a passphrase reader bridge with bells and whistles.
- *
- * On one hand, an API may wish to offer all sorts of passphrase callback
- * possibilities to users, or may have to do so for historical reasons.
- * On the other hand, that same API may have demands from other interfaces,
- * notably from the libcrypto <-> provider interface, which uses
- * OSSL_PASSPHRASE_CALLBACK consistently.
- *
- * The structure and functions below are the fundaments for bridging one
- * passphrase callback form to another.
- *
- * In addition, extra features are included (this may be a growing list):
- *
- * -   password caching.  This is to be used by APIs where it's likely
- *     that the same passphrase may be asked for more than once, but the
- *     user shouldn't get prompted more than once.  For example, this is
- *     useful for OSSL_DECODER, which may have to use a passphrase while
- *     trying to find out what input it has.

-/*
- * Structure to hold whatever the calling user may specify.  This structure
- * is intended to be integrated into API specific structures or to be used
- * as a local on-stack variable type.  Therefore, no functions to allocate
- * or freed it on the heap is offered.
