.IX Header "SYNOPSIS"
#include <openssl/store.h>
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
.SS "General"
.IX Subsection "General"
A \s-1STORE\s0 is a layer of functionality to retrieve a number of supported
objects from a repository of any kind, addressable as a filename or
as a \s-1URI.\s0
.PP
The functionality supports the pattern \*(L"open a channel to the
repository\*(R", \*(L"loop and retrieve one object at a time\*(R", and \*(L"finish up
by closing the channel\*(R".
.PP
The retrieved objects are returned as a wrapper type \fB\s-1OSSL_STORE_INFO\s0\fR,
from which an OpenSSL type can be retrieved.
.SS "\s-1URI\s0 schemes and loaders"
.IX Subsection "URI schemes and loaders"
Support for a \s-1URI\s0 scheme is called a \s-1STORE\s0 \*(L"loader\*(R", and can be added
dynamically from the calling application or from a loadable engine.
.PP
Support for the 'file' scheme is built into \f(CW\*(C`libcrypto\*(C'\fR.
See \fBossl_store\-file\fR\|(7) for more information.
.SS "\s-1UI_METHOD\s0 and pass phrases"
.IX Subsection "UI_METHOD and pass phrases"
The \fB\s-1OSS_STORE\s0\fR \s-1API\s0 does nothing to enforce any specific format or
encoding on the pass phrase that the \fB\s-1UI_METHOD\s0\fR provides.  However,
the pass phrase is expected to be \s-1UTF\-8\s0 encoded.  The result of any
other encoding is undefined.
