## Description of problem:
Using `certtool --sec-param high` per recommendation from certtool generates a smaller key than expected.

## Version of gnutls used:
3.7.3

## Distributor of gnutls (e.g., Ubuntu, Fedora, RHEL)
Ubuntu

## How reproducible:
```
certtool --generate-privkey --bits=4096 --outfile some.key
** Note: You may use '--sec-param High' instead of '--bits 4096'
Generating a 4096 bit RSA private key...
```

OK, lets use `--sec-param high` instead of `--bits=4096`.

## Actual results:
```
certtool --generate-privkey --sec-param high --outfile some.key
Generating a 3072 bit RSA private key...
```


## Expected results:
```
certtool --generate-privkey --sec-param high --outfile some.key
Generating a 4096 bit RSA private key...
```
