Public Class Methods

OpenSSL::Provider.load(name) → provider click to toggle source

This method loads and initializes a provider

static VALUE
ossl_provider_s_load(VALUE klass, VALUE name)
{
    OSSL_PROVIDER *provider = NULL;
    VALUE obj;

    const char *provider_name_ptr = StringValueCStr(name);

    provider = OSSL_PROVIDER_load(NULL, provider_name_ptr);
    if (provider == NULL) {
        ossl_raise(eProviderError, "Failed to load %s provider", provider_name_ptr);
    }
    obj = NewProvider(klass);
    SetProvider(obj, provider);

    return obj;
}

OpenSSL::Provider.provider_names → [provider_name, ...] click to toggle source

Returns an array of currently loaded provider names.

static VALUE
ossl_provider_s_provider_names(VALUE klass)
{
    VALUE ary = rb_ary_new();
    struct ary_with_state cbdata = { ary, 0 };

    int result = OSSL_PROVIDER_do_all(NULL, &push_provider, (void*)&cbdata);
    if (result != 1 ) {
        if (cbdata.state) {
            rb_jump_tag(cbdata.state);
        } else {
            ossl_raise(eProviderError, "Failed to load provider names");
        }
    }

    return ary;
}

Public Instance Methods

inspect → string click to toggle source

Pretty prints this provider.

static VALUE
ossl_provider_inspect(VALUE self)
{
    OSSL_PROVIDER *prov;
    if (RTYPEDDATA_DATA(self) == NULL ) {
        return rb_sprintf("#<%"PRIsVALUE" unloaded provider>", rb_obj_class(self));
    }
    GetProvider(self, prov);

    return rb_sprintf("#<%"PRIsVALUE" name=\"%s\">",
                      rb_obj_class(self), OSSL_PROVIDER_get0_name(prov));
}

name → string click to toggle source

Get the name of this provider.

if this provider is already unloaded, it raises OpenSSL::Provider::ProviderError

static VALUE
ossl_provider_get_name(VALUE self)
{
    OSSL_PROVIDER *prov;
    if (RTYPEDDATA_DATA(self) == NULL) {
        ossl_raise(eProviderError, "Provider already unloaded.");
    }
    GetProvider(self, prov);

    return rb_str_new2(OSSL_PROVIDER_get0_name(prov));
}

unload → true click to toggle source

This method unloads this provider.

if provider unload fails or already unloaded, it raises OpenSSL::Provider::ProviderError

static VALUE
ossl_provider_unload(VALUE self)
{
    OSSL_PROVIDER *prov;
    if (RTYPEDDATA_DATA(self) == NULL) {
        ossl_raise(eProviderError, "Provider already unloaded.");
    }
    GetProvider(self, prov);

    int result = OSSL_PROVIDER_unload(prov);

    if (result != 1) {
        ossl_raise(eProviderError, "Failed to unload provider");
    }
    RTYPEDDATA_DATA(self) = NULL;
    return Qtrue;
