NAME
ossl_store - Store retrieval functions
LIBRARY
libcrypto, -lcrypto
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_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);
