OSSL_STORE(7SSL)                             OpenSSL                             OSSL_STORE(7SSL)

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 filename 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_CERT:
                /* 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);
