.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "OSSL_STORE 7" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
ossl_store - Store retrieval functions Header "SYNOPSIS" #include <openssl/store.h> Header "DESCRIPTION" 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

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".

The retrieved objects are returned as a wrapper type \s-1OSSL_STORE_INFO\s0, from which an OpenSSL type can be retrieved.

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.

Support for the 'file' scheme is built into \*(C`libcrypto\*(C'. See ossl_store-file\|(7) for more information.

Subsection "UI_METHOD and pass phrases" The \s-1OSS_STORE\s0 \s-1API\s0 does nothing to enforce any specific format or encoding on the pass phrase that the \s-1UI_METHOD\s0 provides. However, the pass phrase is expected to be \s-1UTF-8\s0 encoded. The result of any other encoding is undefined.
