=head1 NAME

EVP_set_default_properties
- Set default properties for future algorithm fetches

=head1 SYNOPSIS

 #include <openssl/evp.h>

 int EVP_set_default_properties(OPENSSL_CTX *libctx, const char *propq);

=head1 DESCRIPTION

EVP_set_default_properties() sets the default properties for all
future EVP algorithm fetches, implicit as well as explicit.

=for comment TODO(3.0) We should consider having an EVP document in
section 7 that details everything about implicit vs explicit fetches
and how they relate to properties.

EVP_set_default_properties stores the properties given with the string
I<propq> among the EVP data that's been stored in the library context
given with I<libctx> (NULL signifies the default library context).

Any previous default property for the specified library context will
be dropped.

=head1 RETURN VALUES

EVP_set_default_properties() returns 1 on success, or 0 on failure.
The latter adds an error on the error stack.
