|
|---|
| 5 | OSSL_PROVIDER-base - OpenSSL base provider
|
|---|
| 6 |
|
|---|
| 7 | =head1 DESCRIPTION
|
|---|
| 8 |
|
|---|
| 9 | The OpenSSL base provider supplies the encoding for OpenSSL's
|
|---|
| 10 | asymmetric cryptography.
|
|---|
| 11 |
|
|---|
| 12 | =head2 Properties
|
|---|
| 13 |
|
|---|
| 14 | The implementations in this provider specifically have this property
|
|---|
| 15 | defined:
|
|---|
| 16 |
|
|---|
| 17 | =over 4
|
|---|
| 18 |
|
|---|
| 19 | =item "provider=base"
|
|---|
| 20 |
|
|---|
| 21 | =back
|
|---|
| 22 |
|
|---|
| 23 | It may be used in a property query string with fetching functions.
|
|---|
| 24 |
|
|---|
| 25 | It isn't mandatory to query for this property, except to make sure to get
|
|---|
| 26 | implementations of this provider and none other.
|
|---|
| 27 |
|
|---|
| 28 | =over 4
|
|---|
| 29 |
|
|---|
| 30 | =item "type=parameters"
|
|---|
| 31 |
|
|---|
| 32 | =item "type=private"
|
|---|
| 33 |
|
|---|
| 34 | =item "type=public"
|
|---|
| 35 |
|
|---|
| 36 | =back
|
|---|
| 37 |
|
|---|
| 38 | These may be used in a property query string with fetching functions to select
|
|---|
| 39 | which data are to be encoded. Either the private key material, the public
|
|---|
| 40 | key material or the domain parameters can be selected.
|
|---|
| 41 |
|
|---|
| 42 | =over 4
|
|---|
| 43 |
|
|---|
| 44 | =item "format=der"
|
|---|
| 45 |
|
|---|
| 46 | =item "format=pem"
|
|---|
| 47 |
|
|---|
| 48 | =item "format=text"
|
|---|
| 49 |
|
|---|
| 50 | =back
|
|---|
| 51 |
|
|---|
| 52 | These may be used in a property query string with fetching functions to select
|
|---|
| 53 | the encoding output format. Either the DER, PEM and plaintext are
|
|---|
| 54 | currently permitted.
|
|---|
| 55 |
|
|---|
| 56 | =head1 OPERATIONS AND ALGORITHMS
|
|---|
| 57 |
|
|---|
| 58 | The OpenSSL base provider supports these operations and algorithms:
|
|---|
| 59 |
|
|---|
| 60 | =head2 Asymmetric Key Encoder
|
|---|
| 61 |
|
|---|
| 62 | In addition to "provider=base", some of these encoders define the
|
|---|
| 63 | property "fips=yes", to allow them to be used together with the FIPS
|
|---|
| 64 | provider.
