NAME

       OSSL_PROVIDER-base - OpenSSL base provider

DESCRIPTION

       The OpenSSL base provider supplies the encoding for OpenSSL's asymmetric cryptography.

   Properties
       The implementations in this provider specifically have this property defined:

       "provider=base"

       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.

       "type=parameters"
       "type=private"
       "type=public"

       These may be used in a property query string with fetching functions to  select  which  data  are  to  be
       encoded.   Either  the  private  key  material,  the  public key material or the domain parameters can be
       selected.

       "format=der"
       "format=pem"
       "format=text"

       These may be used in a property query string with  fetching  functions  to  select  the  encoding  output
       format.  Either the DER, PEM and plaintext are currently permitted.

OPERATIONS AND ALGORITHMS

       The OpenSSL base provider supports these operations and algorithms:

   Random Number Generation
       SEED-SRC,  see EVP_RAND-SEED-SRC(7)
       JITTER,  see EVP_RAND-JITTER(7)

       In  addition  to  this provider, the "SEED-SRC" and "JITTER" algorithms are also available in the default
       provider.

   Asymmetric Key Encoder
       RSA
       RSA-PSS
       DH
       DHX
       DSA
       EC
       ED25519
       ED448
       X25519
       X448
       SM2

       In addition to this provider, all of  these  encoding  algorithms  are  also  available  in  the  default
       provider. Some of these algorithms may be used in combination with the FIPS provider.

   Asymmetric Key Decoder
       RSA
       RSA-PSS
       DH
       DHX
       DSA
       EC
       ED25519
       ED448
       X25519
       X448
       SM2
       DER

       In  addition  to  this  provider,  all  of  these  decoding  algorithms are also available in the default
       provider. Some of these algorithms may be used in combination with the FIPS provider.

   Stores
       file
       org.openssl.winstore, see OSSL_STORE-winstore(7)

       In addition to this provider, all of these store algorithms are also available in the default provider.
