+=head1 NAME
+
+EVP_RAND-CTR-DRBG - The CTR DRBG EVP_RAND implementation
+
+=head1 DESCRIPTION
+
+Support for the counter deterministic random bit generator through the
+B<EVP_RAND> API.
+
+=head2 Identity
+
+"CTR-DRBG" is the name for this implementation; it can be used with the
+EVP_RAND_fetch() function.
+
+=head2 Supported parameters
+
+The supported parameters are:
+
+=over 4
+
+=item "state" (B<OSSL_RAND_PARAM_STATE>) <integer>
+
+=item "strength" (B<OSSL_RAND_PARAM_STRENGTH>) <unsigned integer>
+
+=item "reseed_requests" (B<OSSL_DRBG_PARAM_RESEED_REQUESTS>) <unsigned integer>
+
+=item "reseed_time_interval" (B<OSSL_DRBG_PARAM_RESEED_TIME_INTERVAL>) <integer>
+
+=item "max_request" (B<OSSL_DRBG_PARAM_MAX_REQUEST>) <unsigned integer>
+
+=item "min_entropylen" (B<OSSL_DRBG_PARAM_MIN_ENTROPYLEN>) <unsigned integer>
+
+=item "max_entropylen" (B<OSSL_DRBG_PARAM_MAX_ENTROPYLEN>) <unsigned integer>
+
+=item "min_noncelen" (B<OSSL_DRBG_PARAM_MIN_NONCELEN>) <unsigned integer>
+
+=item "max_noncelen" (B<OSSL_DRBG_PARAM_MAX_NONCELEN>) <unsigned integer>
+
+=item "max_perslen" (B<OSSL_DRBG_PARAM_MAX_PERSLEN>) <unsigned integer>
+
+=item "max_adinlen" (B<OSSL_DRBG_PARAM_MAX_ADINLEN>) <unsigned integer>
+
+=item "reseed_counter" (B<OSSL_DRBG_PARAM_RESEED_CTR>) <unsigned integer>
+
+=item "properties" (B<OSSL_DRBG_PARAM_PROPERTIES>) <UTF8 string>
+
+=item "cipher" (B<OSSL_DRBG_PARAM_CIPHER>) <UTF8 string>
+
+These parameters work as described in L<EVP_RAND(3)/PARAMETERS>.
+
+=item "use_derivation_function" (B<OSSL_DRBG_PARAM_USE_DF>) <int>
+
+This Boolean indicates if a derivation function should be used or not.
+A nonzero value (the default) uses the derivation function.  A zero value
+does not.  The FIPS provider always uses the derivation function and attempts
+to set this value result in an error.

+=head1 NOTES
+
+A context for CTR DRBG can be obtained by calling:
+
+ EVP_RAND *rand = EVP_RAND_fetch(NULL, "CTR-DRBG", NULL);
+ EVP_RAND_CTX *rctx = EVP_RAND_CTX_new(rand);
+
+=head1 EXAMPLES
+
+ EVP_RAND *rand;
+ EVP_RAND_CTX *rctx;
+ unsigned char bytes[100];
+ OSSL_PARAM params[2], *p = params;
+ unsigned int strength = 128;
+
+ rand = EVP_RAND_fetch(NULL, "CTR-DRBG", NULL);
+ rctx = EVP_RAND_CTX_new(rand, NULL);
+ EVP_RAND_free(rand);
+
+ *p++ = OSSL_PARAM_construct_utf8_string(OSSL_DRBG_PARAM_CIPHER,
+                                         SN_aes_256_ctr, 0);
+ *p = OSSL_PARAM_construct_end();
+ EVP_RAND_set_ctx_params(rctx, params);
+
+ EVP_RAND_generate(rctx, bytes, sizeof(bytes), strength, 0, NULL, 0);
+
+ EVP_RAND_CTX_free(rctx);
