NAME

       ossl_store - Store retrieval functions

SYNOPSIS

       #include <openssl/store.h>

DESCRIPTION

   General
       A STORE is a layer of functionality to retrieve a number of supported objects from a repository of any kind, addressable as a file name or
       as a URI.

       The functionality supports the pattern "open a channel to the repository", "loop and retrieve one object at a time", and "finish up by
       closing the channel".

       The retrieved objects are returned as a wrapper type OSSL_STORE_INFO, from which an OpenSSL type can be retrieved.

   URI schemes and loaders
       Support for a URI scheme is called a STORE "loader", and can be added dynamically from the calling application or from a loadable engine.

       Support for the 'file' scheme is built into "libcrypto".  See ossl_store-file(7) for more information.

   UI_METHOD and pass phrases
       The OSS_STORE API does nothing to enforce any specific format or encoding on the pass phrase that the UI_METHOD provides.  However, the
       pass phrase is expected to be UTF-8 encoded.  The result of any other encoding is undefined.

EXAMPLES

   A generic call
	OSSL_STORE_CTX *ctx = OSSL_STORE_open("file:/foo/bar/data.pem");

	/*
	 * OSSL_STORE_eof() simulates file semantics for any repository to signal
	 * that no more data can be expected
	 */
	while (!OSSL_STORE_eof(ctx)) {
	    OSSL_STORE_INFO *info = OSSL_STORE_load(ctx);

	    /*
	     * Do whatever is necessary with the OSSL_STORE_INFO,
	     * here just one example
	     */
	    switch (OSSL_STORE_INFO_get_type(info)) {
	    case OSSL_STORE_INFO_X509:
		/* Print the X.509 certificate text */
		X509_print_fp(stdout, OSSL_STORE_INFO_get0_CERT(info));
		/* Print the X.509 certificate PEM output */
		PEM_write_X509(stdout, OSSL_STORE_INFO_get0_CERT(info));
		break;
	    }
	}

	OSSL_STORE_close(ctx);
