=head1 DESCRIPTION
|
|
|
|
|
|
2020-08-17 03:25:08 +08:00
|
|
|
The OpenSSL base provider supplies the encoding for OpenSSL's
|
2020-06-11 07:08:01 +08:00
|
|
|
asymmetric cryptography.

=head2 Properties
|
|
|
|
|
|
|
|
|
|
The implementations in this provider specifically have this property

|
|
|
|
defined:

|
It may be used in a property query string with fetching functions.
|
|
|
|
|
|
|
|
|
|
It isn't mandatory to query for this property, except to make sure to get
|
|
|
|
|
implementations of this provider and none other.

These may be used in a property query string with fetching functions to select
|
2020-08-17 03:25:08 +08:00
|
|
|
which data are to be encoded. Either the private key material, the public
|
2020-06-11 07:08:01 +08:00
|
|
|
key material or the domain parameters can be selected.

2020-08-17 03:25:08 +08:00
|
|
|
the encoding output format. Either the DER, PEM and plaintext are

currently permitted.

=head1 OPERATIONS AND ALGORITHMS
|
|
|
|
|
|
|
|
|
|
The OpenSSL base provider supports these operations and algorithms:

|
|
|
|
2020-08-17 03:25:08 +08:00
|
|
|
In addition to "provider=base", some of these encoders define the
|
2020-06-11 07:08:01 +08:00
|
|
|
property "fips=yes", to allow them to be used together with the FIPS
|
|
|
|
|
provider.
