See <a href="../man7/ossl_store-file.html">ossl_store-file(7)</a> for more information.</p> <h2 id="UI_METHOD-and-pass-phrases">UI_METHOD and pass phrases</h2> <p>The <b>OSS_STORE</b> API does nothing to enforce any specific format or encoding on the pass phrase that the <b>UI_METHOD</b> provides. However, the pass phrase is expected to be UTF-8 encoded. The result of any other encoding is undefined.</p> <h1 id="EXAMPLES">EXAMPLES</h1> <h2 id="A-generic-call">A generic call</h2> <pre><code> 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);</code></pre> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/OSSL_STORE_INFO.html">OSSL_STORE_INFO(3)</a>, <a href="../man3/OSSL_STORE_LOADER.html">OSSL_STORE_LOADER(3)</a>, <a href="../man3/OSSL_STORE_open.html">OSSL_STORE_open(3)</a>, <a href="../man3/OSSL_STORE_expect.html">OSSL_STORE_expect(3)</a>, <a href="../man3/OSSL_STORE_SEARCH.html">OSSL_STORE_SEARCH(3)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2016-2021 The OpenSSL Project Authors.
