+A DSA key can be used for signing only. It is important to

Generating a key for the DSA algorithm is a two-step process. First,
you have to generate parameters from which to generate the key:
these options allow the algorithm used to encrypt the private key and
certificates to be selected. Any PKCS#5 v1.5 or PKCS#12 PBE algorithm name

(as output by the B<list-cipher-algorithms> command is specified then it
is used with PKCS#5 v2.0. For interoperability reasons it is advisable to only
use PKCS#12 algorithms.

Create a private key and then generate a certificate request from it:
- openssl genrsa -out key.pem 1024
+ openssl genrsa -out key.pem 2048
openssl req -new -key key.pem -out req.pem
The same but just using req:
- openssl req -newkey rsa:1024 -keyout key.pem -out req.pem
+ openssl req -newkey rsa:2048 -keyout key.pem -out req.pem
Generate a self signed root certificate:
- openssl req -x509 -newkey rsa:1024 -keyout key.pem -out req.pem
+ openssl req -x509 -newkey rsa:2048 -keyout key.pem -out req.pem

Here we'll assume an application has been configured by its user or admin
to want to use the "ACME" ENGINE if it is available in the version of
OpenSSL the application was compiled with. If it is available, it should be
-used by default for all RSA, DSA, and symmetric cipher operation, otherwise
+used by default for all RSA, DSA, and symmetric cipher operations, otherwise
OpenSSL should use its builtin software as per usual. The following code
illustrates how to approach this;
Here we'll assume we want to load and register all ENGINE implementations
bundled with OpenSSL, such that for any cryptographic algorithm required by
-OpenSSL - if there is an ENGINE that implements it and can be initialise,
+OpenSSL - if there is an ENGINE that implements it and can be initialised,
it should be used. The following code illustrates how this can work;
