  *
- * DRBG Usage
- * ==========
- * The SP 800-90A DRBG allows the user to specify a personalization string
- * for initialization as well as an additional information string for each
- * random number request.  The following code fragments show how a caller
- * uses the API to use the full functionality of the DRBG.
- *
- * Usage without any additional data
- * ---------------------------------
- * gcry_randomize(outbuf, OUTLEN, GCRY_STRONG_RANDOM);
- *
- *
- * Usage with personalization string during initialization
- * -------------------------------------------------------
- * drbg_string_t pers;
- * char personalization[11] = "some-string";
- *
- * drbg_string_fill(&pers, personalization, strlen(personalization));
- * // The reset completely re-initializes the DRBG with the provided
- * // personalization string without changing the DRBG type
- * ret = gcry_control(GCRYCTL_DRBG_REINIT, 0, &pers);
- * gcry_randomize(outbuf, OUTLEN, GCRY_STRONG_RANDOM);
- *
- *
- * Usage with additional information string during random number request
- * ---------------------------------------------------------------------
- * drbg_string_t addtl;
- * char addtl_string[11] = "some-string";
- *
- * drbg_string_fill(&addtl, addtl_string, strlen(addtl_string));
- * // The following call is a wrapper to gcry_randomize() and returns
- * // the same error codes.
- * gcry_randomize_drbg(outbuf, OUTLEN, GCRY_STRONG_RANDOM, &addtl);
- *
- *
- * Usage with personalization and additional information strings
- * -------------------------------------------------------------
- * Just mix both scenarios above.
- *
- *
- * Switch the DRBG type to some other type
- * ---------------------------------------
- * // Switch to CTR DRBG AES-128 without prediction resistance
- * ret = gcry_control(GCRYCTL_DRBG_REINIT, DRBG_NOPR_CTRAES128, NULL);
- * gcry_randomize(outbuf, OUTLEN, GCRY_STRONG_RANDOM);
